So, I I think the the first 50 00:02:42,879 --> 00:02:45,519 thing on our agenda is just um reviewing 51 00:02:45,519 --> 00:02:48,160 our um 52 00:02:48,160 --> 00:02:52,000 our meeting summary. And so, if you 53 00:02:52,000 --> 00:02:54,480 remember, we had a meeting in in May, I 54 00:02:54,480 --> 00:02:56,959 think May 27th, um which is our normal 55 00:02:56,959 --> 00:02:59,360 meeting, went through our normal agenda, 56 00:02:59,360 --> 00:03:00,720 and one of the things that came out of 57 00:03:00,720 --> 00:03:03,360 there were um some recommendations that 58 00:03:03,360 --> 00:03:05,280 we should consider modifications to the 59 00:03:05,280 --> 00:03:09,680 BM. Um then we met again in June um for 60 00:03:09,680 --> 00:03:12,159 an hour and out of that came a 61 00:03:12,159 --> 00:03:13,840 recommendation 62 00:03:13,840 --> 00:03:16,640 um to the to division of water quality 63 00:03:16,640 --> 00:03:18,720 and forestry fire and state lands to 64 00:03:18,720 --> 00:03:21,440 look into actually modifying the burn. 65 00:03:21,440 --> 00:03:25,360 Um, and so the summary I sent out this 66 00:03:25,360 --> 00:03:27,360 time was just for the um, the June 67 00:03:27,360 --> 00:03:29,200 meeting and wanted to just see if 68 00:03:29,200 --> 00:03:33,519 anybody had any comments um, 69 00:03:33,519 --> 00:03:38,117 that any they'd like to change or 70 00:03:38,117 --> 00:03:39,920 [clears throat] any gaps in it. And I 71 00:03:39,920 --> 00:03:42,239 guess if not take a entertain a motion 72 00:03:42,239 --> 00:03:47,830 to approve that summary. 73 00:03:47,840 --> 00:03:50,000 » So move 74 00:03:50,000 --> 00:03:50,959 Thomas. 75 00:03:50,959 --> 00:03:52,159 We have a second. 76 00:03:52,159 --> 00:03:54,480 >> Second, 77 00:03:54,480 --> 00:03:55,760 >> thank you, Joe. 78 00:03:55,760 --> 00:03:58,080 >> All right. All those in favor approving 79 00:03:58,080 --> 00:04:00,480 the summary say I. 80 00:04:00,480 --> 00:04:01,280 >> I. 81 00:04:01,280 --> 00:04:03,680 >> Any opposed? 82 00:04:03,680 --> 00:04:06,159 All right. It carries unanimously. Thank 83 00:04:06,159 --> 00:04:10,000 you. Um All right. Well, the next thing 84 00:04:10,000 --> 00:04:12,400 on our agenda is just an update on the 85 00:04:12,400 --> 00:04:14,239 lake. 86 00:04:14,239 --> 00:04:15,280 I don't know if Ryan 87 00:04:15,280 --> 00:04:16,639 >> Yeah, I'm sorry. You got to put it with 88 00:04:16,639 --> 00:04:19,919 me again. Um I think I start this off. 89 00:04:19,919 --> 00:04:23,312 Um Christine's reading the slides. 90 00:04:23,312 --> 00:04:30,070 [snorts] 91 00:04:30,080 --> 00:04:32,639 » Okay, we're gonna jump in. Go ahead. 92 00:04:32,639 --> 00:04:33,680 We'll just jump right in. 93 00:04:33,680 --> 00:04:35,520 >> Great. 94 00:04:35,520 --> 00:04:38,080 >> There's our disclaimer. Um this is 95 00:04:38,080 --> 00:04:39,600 important. There's a lot of provisional 96 00:04:39,600 --> 00:04:41,360 data. There's a lot of assumptions that 97 00:04:41,360 --> 00:04:44,639 we uh are open with. So, um keep that in 98 00:04:44,639 --> 00:04:47,680 mind. Here's our official disclaimer. 99 00:04:47,680 --> 00:04:48,960 All right. Let's just start off with 100 00:04:48,960 --> 00:04:50,639 what you guys already all know. I'm 101 00:04:50,639 --> 00:04:52,000 hoping you guys are always looking at 102 00:04:52,000 --> 00:04:54,080 the great salt lake hydro mapper or 103 00:04:54,080 --> 00:04:56,160 looking at our data through the national 104 00:04:56,160 --> 00:04:58,479 water dashboard etc. South arm great 105 00:04:58,479 --> 00:05:00,240 salt lake elevations [clears throat] I'm 106 00:05:00,240 --> 00:05:03,040 showing data from October 1st 2021 in 107 00:05:03,040 --> 00:05:05,280 the current period. Uh the period of 108 00:05:05,280 --> 00:05:10,639 record low is 4188.5 set in uh 2022. 109 00:05:10,639 --> 00:05:13,199 Um the most recent data here at the end 110 00:05:13,199 --> 00:05:15,919 of the plot, the daily value on August 111 00:05:15,919 --> 00:05:19,039 5th came in at 4190.6. 112 00:05:19,039 --> 00:05:21,120 That's down 1.7 feet [clears throat] 113 00:05:21,120 --> 00:05:23,919 since the seasonal high that was not 114 00:05:23,919 --> 00:05:26,400 influenced by the sesh. That little blue 115 00:05:26,400 --> 00:05:29,919 peak right there is a was a sesh event. 116 00:05:29,919 --> 00:05:33,680 Okay, I'm not counting that. So we're [clears throat] we're saying the 117 00:05:33,680 --> 00:05:37,680 seasonal high was um about 310 of a feet 118 00:05:37,680 --> 00:05:40,320 lower. Um, and so the bottom line is 119 00:05:40,320 --> 00:05:41,840 since that seasonal peak, the lake is 120 00:05:41,840 --> 00:05:46,400 down about 1.7 ft. All right. Um, this 121 00:05:46,400 --> 00:05:49,440 puts us 2.1 ft above the period of 122 00:05:49,440 --> 00:05:55,280 record low. All right. So, something to keep in mind going forward as we 123 00:05:55,280 --> 00:05:57,634 anticipate, you know, snowpack, 124 00:05:57,634 --> 00:05:59,360 [clears throat] you know, next season's 125 00:05:59,360 --> 00:06:02,320 evaporation, etc. All right. Similarly, 126 00:06:02,320 --> 00:06:04,479 for the north arm, the daily value 127 00:06:04,479 --> 00:06:06,479 computed for August 4th came in at 128 00:06:06,479 --> 00:06:08,240 4190.2. 129 00:06:08,240 --> 00:06:11,280 That's down about 1.4 ft since the 130 00:06:11,280 --> 00:06:13,360 seasonal peak, 131 00:06:13,360 --> 00:06:16,720 this guy back here. Um, and that's 1.7 132 00:06:16,720 --> 00:06:18,720 ft above the period of record low, which 133 00:06:18,720 --> 00:06:21,440 is also 4188.5. 134 00:06:21,440 --> 00:06:23,120 Both the north and south have the same 135 00:06:23,120 --> 00:06:26,080 period of record low. Okay, so that's 136 00:06:26,080 --> 00:06:28,240 the lake elevation data. Now, let's get 137 00:06:28,240 --> 00:06:30,800 into major surface water inflow at our 138 00:06:30,800 --> 00:06:32,349 on our stream gauges. 139 00:06:32,349 --> 00:06:32,800 >> [clears throat] 140 00:06:32,800 --> 00:06:34,720 >> First I just want to remark that these 141 00:06:34,720 --> 00:06:37,520 cumulative flow hydrographs are coming 142 00:06:37,520 --> 00:06:40,160 from a relatively new USGS software 143 00:06:40,160 --> 00:06:42,720 package called high swap. That's the 144 00:06:42,720 --> 00:06:44,319 hydraologic surface water analysis 145 00:06:44,319 --> 00:06:46,319 package. [clears throat] This is a a 146 00:06:46,319 --> 00:06:48,560 package of Python code that helps you 147 00:06:48,560 --> 00:06:52,080 visualize USGS data publicly available. 148 00:06:52,080 --> 00:06:54,160 Just Google it and you'll find it. 149 00:06:54,160 --> 00:06:55,440 That's what was used to make these 150 00:06:55,440 --> 00:06:56,960 plots. So here we have a plot of 151 00:06:56,960 --> 00:06:59,204 cumulative discharge in acre feet. 152 00:06:59,204 --> 00:07:00,080 [clears throat] 153 00:07:00,080 --> 00:07:03,520 Y axis is or the excuse me the Y axis is 154 00:07:03,520 --> 00:07:05,099 in acre feet. It's a linear 155 00:07:05,099 --> 00:07:07,840 [clears throat] axis and the X axis is a 156 00:07:07,840 --> 00:07:09,520 water year. The bold black line is the 157 00:07:09,520 --> 00:07:12,560 current water year. Uh this top dash 158 00:07:12,560 --> 00:07:14,240 line is the highest ever measured 159 00:07:14,240 --> 00:07:16,560 cumulative flow for this site. That was 160 00:07:16,560 --> 00:07:18,560 in 1984. 161 00:07:18,560 --> 00:07:20,560 Uh small dash line at the bottom. Lowest 162 00:07:20,560 --> 00:07:23,680 measured cumulative flow 1992. And then 163 00:07:23,680 --> 00:07:26,080 the green shaded zone is the 25th to 164 00:07:26,080 --> 00:07:29,759 75th percentile range. And so the the 165 00:07:29,759 --> 00:07:31,280 middle of that green zone would be the 166 00:07:31,280 --> 00:07:34,580 right the 50th percentile. Um, as 167 00:07:34,580 --> 00:07:36,319 [clears throat] of August a couple of 168 00:07:36,319 --> 00:07:38,240 days ago, the total volume of water 169 00:07:38,240 --> 00:07:41,599 passing this gauge was at 541,000 acre 170 00:07:41,599 --> 00:07:44,800 feet plus or minus a little bit. Next 171 00:07:44,800 --> 00:07:48,400 slide or hit the next button. Exact same 172 00:07:48,400 --> 00:07:50,319 format plot. This is for the Weaver 173 00:07:50,319 --> 00:07:53,440 River near Plane City. Um, and first of 174 00:07:53,440 --> 00:07:56,080 all note where the black line is 175 00:07:56,080 --> 00:07:58,639 relative to those benchmarks. So at this 176 00:07:58,639 --> 00:08:01,120 site we're we're hugging the the lowest 177 00:08:01,120 --> 00:08:03,440 uh measured cumulative flow. Currently 178 00:08:03,440 --> 00:08:06,720 we're at 54,000 acre feet of the Weber 179 00:08:06,720 --> 00:08:09,280 River near Plane City. All right, next 180 00:08:09,280 --> 00:08:13,280 slide or next plot. Dog and drain. I 181 00:08:13,280 --> 00:08:16,479 made a huge error on this guy last time 182 00:08:16,479 --> 00:08:19,440 we met. I had added a zero to this total 183 00:08:19,440 --> 00:08:21,120 here. You might remember some very 184 00:08:21,120 --> 00:08:23,360 surprised faces in there. You guys knew 185 00:08:23,360 --> 00:08:25,120 I was wrong. you were just being nice to 186 00:08:25,120 --> 00:08:27,440 me for not saying, "Hey, you're there's 187 00:08:27,440 --> 00:08:29,680 something really wrong." Yes, I made a 188 00:08:29,680 --> 00:08:32,719 mistake. I apologize. Um anyway, as of 189 00:08:32,719 --> 00:08:34,080 early August, the total volume of water 190 00:08:34,080 --> 00:08:38,800 passing this gauge is 46, uh 882 191 00:08:38,800 --> 00:08:41,680 um acre feet and you know, we're we're 192 00:08:41,680 --> 00:08:44,080 just below the the 25th percentile. And 193 00:08:44,080 --> 00:08:46,480 then the Farmington Bay outflow gauge, 194 00:08:46,480 --> 00:08:48,160 same [clears throat] format plot 195 00:08:48,160 --> 00:08:51,040 currently, or at least as of July 29th. 196 00:08:51,040 --> 00:08:53,120 There's some more recent data um that 197 00:08:53,120 --> 00:08:55,680 are incomplete, some rating things we're 198 00:08:55,680 --> 00:08:57,600 trying to tweak. So we we only have 199 00:08:57,600 --> 00:08:59,680 daily values up to July 29 to compute 200 00:08:59,680 --> 00:09:01,760 that bold black line, but close enough 201 00:09:01,760 --> 00:09:03,519 to the current period, it's about 202 00:09:03,519 --> 00:09:07,750 195,000 aces 203 00:09:07,760 --> 00:09:10,080 within this 25th to 75th percentile 204 00:09:10,080 --> 00:09:12,399 range. Um, if you add [clears throat] 205 00:09:12,399 --> 00:09:14,880 all these numbers up, 206 00:09:14,880 --> 00:09:17,279 uh, and also to put this in perspective 207 00:09:17,279 --> 00:09:19,519 with the historic data, um, I have this 208 00:09:19,519 --> 00:09:22,480 bar chart. So, here's the current water 209 00:09:22,480 --> 00:09:24,720 year, 2026. If you add up those 210 00:09:24,720 --> 00:09:26,080 cumulative flows for all those gauges, 211 00:09:26,080 --> 00:09:28,800 we're at about 837,000 212 00:09:28,800 --> 00:09:30,800 acre feet. 213 00:09:30,800 --> 00:09:33,040 But I have the previous water years here 214 00:09:33,040 --> 00:09:36,399 going back to 2014 on this bar chart. 215 00:09:36,399 --> 00:09:39,760 All right. So last water year 2025 we 216 00:09:39,760 --> 00:09:42,399 had uh 1,161,000 217 00:09:42,399 --> 00:09:44,800 acre feet. I'm rounding as you can tell. 218 00:09:44,800 --> 00:09:46,720 Uh 2024 219 00:09:46,720 --> 00:09:51,360 2,100,000 acre feet. 2025 2.3 million 220 00:09:51,360 --> 00:09:54,480 acre feet and so on. But you can see 221 00:09:54,480 --> 00:09:58,959 currently um we are above 2021 or 2022 222 00:09:58,959 --> 00:10:01,279 um which were really really bad years. 223 00:10:01,279 --> 00:10:03,279 Um, but anyway, this plot gives you a 224 00:10:03,279 --> 00:10:05,920 nice perspective on what the total line 225 00:10:05,920 --> 00:10:08,399 of flows look like at these gauges back 226 00:10:08,399 --> 00:10:11,839 to 2014. Are there any questions? 227 00:10:11,839 --> 00:10:13,040 >> Very cool. 228 00:10:13,040 --> 00:10:17,920 >> Yeah. Um, okay. And then, um, we'll wrap 229 00:10:17,920 --> 00:10:19,839 up my little segment here before we do a 230 00:10:19,839 --> 00:10:20,800 little more a little later in the 231 00:10:20,800 --> 00:10:22,079 meeting, but just recent discharge 232 00:10:22,079 --> 00:10:23,600 measurements at the Great Salt Lake 233 00:10:23,600 --> 00:10:25,200 Bridge at Lakeside. So, this is the Far 234 00:10:25,200 --> 00:10:28,320 West. This is not the new breach. Uh 235 00:10:28,320 --> 00:10:30,480 basically we've had zero flows at this 236 00:10:30,480 --> 00:10:33,360 site since uh April. Um and that's 237 00:10:33,360 --> 00:10:35,600 indicated with this flat line here at 238 00:10:35,600 --> 00:10:38,320 the zero mark on uh the cubic foot per 239 00:10:38,320 --> 00:10:40,399 second scale on the y axis there. This 240 00:10:40,399 --> 00:10:42,800 is showing data from October 1st to the 241 00:10:42,800 --> 00:10:44,560 current period. So basically we're high 242 00:10:44,560 --> 00:10:46,720 and dry at the site right now. And we'll 243 00:10:46,720 --> 00:10:50,320 have more as proof of the agenda. 244 00:10:50,320 --> 00:10:53,360 >> Okay. Quick update on salinities. We 245 00:10:53,360 --> 00:10:56,399 actually the last set of samples we got 246 00:10:56,399 --> 00:10:58,480 was in view. So, I'm going to show those 247 00:10:58,480 --> 00:10:59,920 real fast and then I'll show you some 248 00:10:59,920 --> 00:11:02,000 updated salinities from other locations. 249 00:11:02,000 --> 00:11:05,279 But from our um Southarm monitoring 250 00:11:05,279 --> 00:11:08,480 network, as of June 22nd, 2026, the 251 00:11:08,480 --> 00:11:12,560 salinities ranged from 122 to 124 grams 252 00:11:12,560 --> 00:11:14,800 per liter. Um that's up about four or 253 00:11:14,800 --> 00:11:18,160 five since our seasonal low in April. 254 00:11:18,160 --> 00:11:20,480 And uh the water column is pretty well 255 00:11:20,480 --> 00:11:23,200 mixed at this point. Our more recent 256 00:11:23,200 --> 00:11:25,279 salinities we have uh from the new 257 00:11:25,279 --> 00:11:27,440 breach. We measured salinity yesterday 258 00:11:27,440 --> 00:11:29,839 and we're getting 131 gram per liter. So 259 00:11:29,839 --> 00:11:32,079 that's kind of what we're seeing uh at 260 00:11:32,079 --> 00:11:34,160 the brereech north to south flow which 261 00:11:34,160 --> 00:11:36,959 we are seeing now is 273 grams per 262 00:11:36,959 --> 00:11:38,959 liter. And then we also got a 263 00:11:38,959 --> 00:11:41,040 measurement from saltier our where the 264 00:11:41,040 --> 00:11:42,800 lake elevation gauge is for the south 265 00:11:42,800 --> 00:11:45,600 arm that was also 131 gram per liter. of 266 00:11:45,600 --> 00:11:47,519 that based on those if we assume those 267 00:11:47,519 --> 00:11:49,200 are representative of the south arm 268 00:11:49,200 --> 00:11:50,800 which this time of year is pretty good 269 00:11:50,800 --> 00:11:53,200 assumption um we're up 13 grams per 270 00:11:53,200 --> 00:11:56,480 liter since April and actually I'll use 271 00:11:56,480 --> 00:11:59,839 those August measurements for the fall 272 00:11:59,839 --> 00:12:02,079 and uh spring predictions just because 273 00:12:02,079 --> 00:12:04,800 it's I would rather rely on our more 274 00:12:04,800 --> 00:12:06,399 recent measurement rather than trying to 275 00:12:06,399 --> 00:12:09,519 estimate from June forward. So just just 276 00:12:09,519 --> 00:12:12,639 to give you a little info on that um the 277 00:12:12,639 --> 00:12:14,720 volume weighted methodology requires 278 00:12:14,720 --> 00:12:17,600 measurements from our four sites from 279 00:12:17,600 --> 00:12:20,399 where GU collects samples. So um the 280 00:12:20,399 --> 00:12:21,920 most recent volume weighted salinity 281 00:12:21,920 --> 00:12:24,639 estimate we have is from June 22nd and 282 00:12:24,639 --> 00:12:27,839 that is 123 grams per liter for the 283 00:12:27,839 --> 00:12:29,519 upper bion layer volume weighted and the 284 00:12:29,519 --> 00:12:31,600 full depth. But Gle did go out 285 00:12:31,600 --> 00:12:33,600 yesterday. So we have a new fresh set of 286 00:12:33,600 --> 00:12:35,360 samples and we're working on getting 287 00:12:35,360 --> 00:12:37,680 those salinities uh measured right away. 288 00:12:37,680 --> 00:12:40,639 So I can send out an updated volume 289 00:12:40,639 --> 00:12:42,720 weighted salinity probably later today 290 00:12:42,720 --> 00:12:46,870 or tomorrow for everybody. 291 00:12:46,880 --> 00:12:48,959 Looking at our salt south arm salt mass 292 00:12:48,959 --> 00:12:51,519 trend. So this is from 2022 to the 293 00:12:51,519 --> 00:12:54,480 present. Southarm salt mass is in 294 00:12:54,480 --> 00:12:57,839 millions of tons on the y- axis. And our 295 00:12:57,839 --> 00:13:00,639 most recent again measurement which we 296 00:13:00,639 --> 00:13:04,959 uh I used the um the G slept sample set 297 00:13:04,959 --> 00:13:08,959 from June 2nd was 856 million tons as of 298 00:13:08,959 --> 00:13:11,920 June 22nd. You can see you can see we're 299 00:13:11,920 --> 00:13:14,399 kind of still following that that same 300 00:13:14,399 --> 00:13:18,240 trend of uh decreasing 27 million tons 301 00:13:18,240 --> 00:13:21,360 per year roughly. If we look at uh those 302 00:13:21,360 --> 00:13:24,560 values in the context of elevation and 303 00:13:24,560 --> 00:13:26,399 mass, you can kind of see where we fit 304 00:13:26,399 --> 00:13:30,720 as of June 22nd 123 856 million tons and 305 00:13:30,720 --> 00:13:33,360 we were sitting at 4191.4 at that point 306 00:13:33,360 --> 00:13:35,920 kind of clustered right around um this 307 00:13:35,920 --> 00:13:38,880 black dot cluster. If I just put on our 308 00:13:38,880 --> 00:13:41,360 August 4th measurement from those two 309 00:13:41,360 --> 00:13:44,399 locations again salinities are 131 gram 310 00:13:44,399 --> 00:13:47,519 per liter 864 million tons. If I 311 00:13:47,519 --> 00:13:49,279 extrapolate that concentration across 312 00:13:49,279 --> 00:13:51,040 the volume of the south arm at that 313 00:13:51,040 --> 00:13:54,480 time, which the lake was at 4190.6. 314 00:13:54,480 --> 00:13:56,639 So I think that's our best estimate of 315 00:13:56,639 --> 00:13:58,639 what current conditions are right about 316 00:13:58,639 --> 00:14:02,959 now. I'm sitting at 131 grams per liter. 317 00:14:02,959 --> 00:14:05,199 >> Okay. And I think that's our first 318 00:14:05,199 --> 00:14:07,680 segment, the end of our first segment. 319 00:14:07,680 --> 00:14:08,320 Great. 320 00:14:08,320 --> 00:14:09,680 >> Thank you. 321 00:14:09,680 --> 00:14:14,310 >> Unless there's any questions. 322 00:14:14,320 --> 00:14:17,440 » Well, great. Well, Ben, could you you're 323 00:14:17,440 --> 00:14:19,519 next on the agenda. Just an update on 324 00:14:19,519 --> 00:14:21,760 the Burm that's been going on there. 325 00:14:21,760 --> 00:14:24,240 >> Well, we lowered the recommendation of 326 00:14:24,240 --> 00:14:27,040 the committee. I want to give a shout 327 00:14:27,040 --> 00:14:29,279 out to water resources for helping uh 328 00:14:29,279 --> 00:14:32,240 with construction 329 00:14:32,240 --> 00:14:35,199 uh oversight. So, Eric and BJ did a 330 00:14:35,199 --> 00:14:38,160 great job making that happen. And then 331 00:14:38,160 --> 00:14:40,639 also to Union Pacific, they also 332 00:14:40,639 --> 00:14:42,480 volunteered their time and labor and 333 00:14:42,480 --> 00:14:44,320 everything to the gym. So that was 334 00:14:44,320 --> 00:14:45,839 awesome. We were able to get that done 335 00:14:45,839 --> 00:14:49,440 within days of asking them. So [cough] 336 00:14:49,440 --> 00:14:50,160 everything [clears throat] went as 337 00:14:50,160 --> 00:14:52,160 planned. I think they got it down to the 338 00:14:52,160 --> 00:14:56,079 elevation 4183 as uniform as possible 339 00:14:56,079 --> 00:14:57,839 for Craig's request. I guess we'll have 340 00:14:57,839 --> 00:15:02,560 to see if uh surveys represent that, but 341 00:15:02,560 --> 00:15:03,920 we tried to get it down to a nice 342 00:15:03,920 --> 00:15:07,199 uniform elevation. And right now it's 343 00:15:07,199 --> 00:15:08,720 Yeah, it's open. We're looking forward 344 00:15:08,720 --> 00:15:10,240 to understanding, you know, what type of 345 00:15:10,240 --> 00:15:11,920 flows we're seeing through that and 346 00:15:11,920 --> 00:15:14,000 reconvening as we get more information, 347 00:15:14,000 --> 00:15:17,040 but we did work with USGS to increase 348 00:15:17,040 --> 00:15:18,880 monitoring. So, I think that's also well 349 00:15:18,880 --> 00:15:21,440 underway so we can keep tabs under the 350 00:15:21,440 --> 00:15:25,519 on this. That's all I have anybody has 351 00:15:25,519 --> 00:15:28,800 questions about it. So, building the BM 352 00:15:28,800 --> 00:15:31,199 seemed pretty easy for the railroad. 353 00:15:31,199 --> 00:15:33,040 This seemed like it would be more 354 00:15:33,040 --> 00:15:35,040 difficult. Did they say anything about 355 00:15:35,040 --> 00:15:35,519 how 356 00:15:35,519 --> 00:15:37,600 >> I think they were pretty good. I mean, 357 00:15:37,600 --> 00:15:39,600 um, they got it done in like two days, 358 00:15:39,600 --> 00:15:41,839 so I think it was pretty simple for 359 00:15:41,839 --> 00:15:44,399 them. So, I expected it might be a 360 00:15:44,399 --> 00:15:46,160 little more challenging to to get down, 361 00:15:46,160 --> 00:15:48,560 but they 362 00:15:48,560 --> 00:15:48,959 >> awesome. 363 00:15:48,959 --> 00:15:53,440 >> We do have one slight issue, which is uh 364 00:15:53,440 --> 00:15:55,680 there's a there was a cation order of 365 00:15:55,680 --> 00:15:58,639 their quarry based on some requirements 366 00:15:58,639 --> 00:16:02,560 that need to be met. So, if we end up 367 00:16:02,560 --> 00:16:04,240 needing to raise the B again, we're 368 00:16:04,240 --> 00:16:05,600 going to have to probably source some 369 00:16:05,600 --> 00:16:08,160 rock. figure that out. But we're trying 370 00:16:08,160 --> 00:16:09,759 to work through that and [clears throat] 371 00:16:09,759 --> 00:16:11,759 figure out what can be done or how we 372 00:16:11,759 --> 00:16:13,120 can help on that. But 373 00:16:13,120 --> 00:16:15,279 >> strong 374 00:16:15,279 --> 00:16:16,639 pit 375 00:16:16,639 --> 00:16:19,279 >> uh [clears throat] 376 00:16:19,279 --> 00:16:22,399 strong is is just about a mile away from 377 00:16:22,399 --> 00:16:26,949 Lakewood. 378 00:16:26,959 --> 00:16:28,399 » Nice. Yeah, I don't think it's 379 00:16:28,399 --> 00:16:30,480 insurmountable. I think just ends up not 380 00:16:30,480 --> 00:16:31,839 being free, which we've been pretty 381 00:16:31,839 --> 00:16:33,519 accustomed to lately and that's pretty 382 00:16:33,519 --> 00:16:34,320 nice. 383 00:16:34,320 --> 00:16:36,959 allows us to invest into other 384 00:16:36,959 --> 00:16:39,839 activities. So 385 00:16:39,839 --> 00:16:41,839 anyway, that's all I have for 386 00:16:41,839 --> 00:16:43,759 >> Okay, any questions? 387 00:16:43,759 --> 00:16:46,160 >> Maybe you can give them some cookies. 388 00:16:46,160 --> 00:16:48,079 >> I didn't like that. I think the first 389 00:16:48,079 --> 00:16:52,000 time we took them to to cook dinner. So, 390 00:16:52,000 --> 00:16:54,000 >> I was amazed when like, oh my goodness, 391 00:16:54,000 --> 00:16:55,440 you got it. It's done. 392 00:16:55,440 --> 00:16:57,600 >> Yeah, that included everything. The 393 00:16:57,600 --> 00:16:59,519 making sure everybody needed to know 394 00:16:59,519 --> 00:17:02,160 knew and all of the other pieces. So 395 00:17:02,160 --> 00:17:04,000 there's a lot of work in between a lot 396 00:17:04,000 --> 00:17:08,361 of help from water resources and 397 00:17:08,361 --> 00:17:09,199 [snorts] 398 00:17:09,199 --> 00:17:12,559 >> what you said you said the the sesh 399 00:17:12,559 --> 00:17:13,280 thing 400 00:17:13,280 --> 00:17:16,160 >> would you kind of help me understand 401 00:17:16,160 --> 00:17:19,520 um uni Pacific is concerned about that 402 00:17:19,520 --> 00:17:22,480 at a certain level help me 403 00:17:22,480 --> 00:17:25,039 >> well I mean as I don't know what 404 00:17:25,039 --> 00:17:26,480 conversation you're referring to but I 405 00:17:26,480 --> 00:17:28,559 think in general these sessions have 406 00:17:28,559 --> 00:17:30,559 been known to take out rail cars if they 407 00:17:30,559 --> 00:17:32,880 don't protect the costway proply so 408 00:17:32,880 --> 00:17:35,039 they're constantly like rebuilding rock 409 00:17:35,039 --> 00:17:37,120 walls or stabilizing them and keeping 410 00:17:37,120 --> 00:17:38,720 the railroad from sinking. 411 00:17:38,720 --> 00:17:42,160 >> But in our case the you know I think we 412 00:17:42,160 --> 00:17:44,559 all agree that a session is what took 413 00:17:44,559 --> 00:17:46,799 out the burm the first time it lowered 414 00:17:46,799 --> 00:17:48,640 and made its own v notch and then 415 00:17:48,640 --> 00:17:50,160 subsequent lowering of that has been 416 00:17:50,160 --> 00:17:52,080 through just erosion based on like 417 00:17:52,080 --> 00:17:54,400 didn't have all the protective rod would 418 00:17:54,400 --> 00:17:56,880 have been in there. So now uh you know 419 00:17:56,880 --> 00:17:58,080 one of the things that we're considering 420 00:17:58,080 --> 00:18:00,640 and discussing is you know one through 421 00:18:00,640 --> 00:18:02,320 the Jacob's proposal when we asked about 422 00:18:02,320 --> 00:18:04,480 like a more intelligent structure that 423 00:18:04,480 --> 00:18:06,480 could you know go up and down from the 424 00:18:06,480 --> 00:18:08,080 bottom and all the things and we realize 425 00:18:08,080 --> 00:18:09,520 that's going to be really expensive. But 426 00:18:09,520 --> 00:18:11,280 one thing that did come with that is the 427 00:18:11,280 --> 00:18:13,200 geotech was the big question mark on 428 00:18:13,200 --> 00:18:15,600 that. But we could probably learn a lot 429 00:18:15,600 --> 00:18:17,919 about what's necessary for the 430 00:18:17,919 --> 00:18:20,400 geotechnical um you know stabilization 431 00:18:20,400 --> 00:18:22,720 of that and what what support structure 432 00:18:22,720 --> 00:18:25,200 um just by simply uh starting that 433 00:18:25,200 --> 00:18:26,640 project by doing a component of putting 434 00:18:26,640 --> 00:18:29,919 in like jetties uh in front of the burm 435 00:18:29,919 --> 00:18:31,520 and I think that even if we stuck with a 436 00:18:31,520 --> 00:18:34,320 rockill structure uh those jetties would 437 00:18:34,320 --> 00:18:36,400 protect from siches and make it so we're 438 00:18:36,400 --> 00:18:40,080 more um I guess diligent or intentional 439 00:18:40,080 --> 00:18:41,919 about lowering the burm and not just 440 00:18:41,919 --> 00:18:44,240 letting session should, you know, catch 441 00:18:44,240 --> 00:18:46,880 us on, you know, flat fling 442 00:18:46,880 --> 00:18:48,640 it by accident. This time it worked out 443 00:18:48,640 --> 00:18:51,360 great. We've got a great lucky track 444 00:18:51,360 --> 00:18:53,679 record on the B, but we want to be more 445 00:18:53,679 --> 00:18:55,440 intentional for the future. 446 00:18:55,440 --> 00:18:56,080 >> Thank you. 447 00:18:56,080 --> 00:18:58,960 >> Yeah. 448 00:18:58,960 --> 00:19:00,640 >> Great. And then do you have any other 449 00:19:00,640 --> 00:19:01,360 updates? 450 00:19:01,360 --> 00:19:03,440 >> Um, no, nothing too crazy. I think just 451 00:19:03,440 --> 00:19:06,640 maybe an update on the CMP. We're going 452 00:19:06,640 --> 00:19:08,320 to incorporate, you know, salinity 453 00:19:08,320 --> 00:19:10,160 management that we've discussed here as 454 00:19:10,160 --> 00:19:12,160 a group into that. But one of the things 455 00:19:12,160 --> 00:19:14,559 that we're doing in our CMP and 456 00:19:14,559 --> 00:19:16,160 hopefully everybody's heard this like a 457 00:19:16,160 --> 00:19:17,200 hundred times is we're kind of 458 00:19:17,200 --> 00:19:19,120 segregating out these, you know, 459 00:19:19,120 --> 00:19:21,360 management activities from the CMP. So 460 00:19:21,360 --> 00:19:23,679 the CMP is really how we make decisions 461 00:19:23,679 --> 00:19:25,200 when someone's asking to use sovereign 462 00:19:25,200 --> 00:19:26,720 lands. And then because we don't want 463 00:19:26,720 --> 00:19:28,320 these things to get, you know, dried up 464 00:19:28,320 --> 00:19:30,080 and dusted sitting on a shelf over 10 465 00:19:30,080 --> 00:19:32,480 years, we're taking the like day-to-day 466 00:19:32,480 --> 00:19:35,039 management, the information, the kind of 467 00:19:35,039 --> 00:19:37,520 book report aspect of our old CMPS and 468 00:19:37,520 --> 00:19:39,840 putting that on our website um and 469 00:19:39,840 --> 00:19:41,840 making an interactive, you know, here's 470 00:19:41,840 --> 00:19:44,000 the lake level, here's the salinity, 471 00:19:44,000 --> 00:19:45,200 here are the things that we're doing 472 00:19:45,200 --> 00:19:49,919 today. It doesn't really makeision. 473 00:19:49,919 --> 00:19:51,360 It's just more about transparency for 474 00:19:51,360 --> 00:19:52,720 the public so people can see like what 475 00:19:52,720 --> 00:19:54,080 we're doing and then as we learn new 476 00:19:54,080 --> 00:19:56,320 information or like you know develop 477 00:19:56,320 --> 00:19:57,919 protocols for like the firm or 478 00:19:57,919 --> 00:20:00,000 management of that we don't have to wait 479 00:20:00,000 --> 00:20:01,919 10 years before we can tell people how 480 00:20:01,919 --> 00:20:03,120 we're doing that we can update the 481 00:20:03,120 --> 00:20:05,360 website immediately and show people how 482 00:20:05,360 --> 00:20:07,039 that works. So we're really excited 483 00:20:07,039 --> 00:20:08,799 about that. I think it'll have a there 484 00:20:08,799 --> 00:20:10,640 will be a lot of the work that we've 485 00:20:10,640 --> 00:20:12,480 done as a committee that shows up you 486 00:20:12,480 --> 00:20:14,000 know there there will also be a lot of 487 00:20:14,000 --> 00:20:15,919 other agency partner information. We'll 488 00:20:15,919 --> 00:20:17,840 try to filter people to the appropriate 489 00:20:17,840 --> 00:20:19,360 places so they can go to the right spot 490 00:20:19,360 --> 00:20:21,039 to get the information so we're not 491 00:20:21,039 --> 00:20:23,120 having to retell any of your stories and 492 00:20:23,120 --> 00:20:24,799 we can direct people to the the right 493 00:20:24,799 --> 00:20:27,360 spots. So that's probably the the 494 00:20:27,360 --> 00:20:30,240 biggest thing there and I don't think we 495 00:20:30,240 --> 00:20:32,000 have much else to update. 496 00:20:32,000 --> 00:20:34,080 >> You know anybody has specific questions? 497 00:20:34,080 --> 00:20:38,240 >> One of the u the ideas that Envision 498 00:20:38,240 --> 00:20:40,880 Utah is incorporating in the VIP is for 499 00:20:40,880 --> 00:20:43,679 these various scenarios an if then 500 00:20:43,679 --> 00:20:45,600 >> kind of thing. And it I think it helps 501 00:20:45,600 --> 00:20:48,640 the public understand that if we don't 502 00:20:48,640 --> 00:20:50,960 do something then this could be the 503 00:20:50,960 --> 00:20:51,440 outcome. 504 00:20:51,440 --> 00:20:51,760 >> Sure. 505 00:20:51,760 --> 00:20:54,559 >> If we do do something in a timely manner 506 00:20:54,559 --> 00:20:56,480 then this is what the benefit of that 507 00:20:56,480 --> 00:20:58,720 management decision gives. 508 00:20:58,720 --> 00:21:00,240 >> So I don't know. 509 00:21:00,240 --> 00:21:01,919 >> That's great. I think we can try to 510 00:21:01,919 --> 00:21:05,200 consider that. We have you know kind of 511 00:21:05,200 --> 00:21:07,760 a limited amount of funding and time to 512 00:21:07,760 --> 00:21:09,520 finish this. It's already gone a little 513 00:21:09,520 --> 00:21:12,080 longer than than more expensive than we 514 00:21:12,080 --> 00:21:14,159 would like. But um I think those are the 515 00:21:14,159 --> 00:21:15,760 kinds of things that you know given the 516 00:21:15,760 --> 00:21:17,679 fact that we're taking that component 517 00:21:17,679 --> 00:21:19,280 out of the plan. We don't have to wait 518 00:21:19,280 --> 00:21:20,880 10 years to do that. We can work on that 519 00:21:20,880 --> 00:21:21,600 now [clears throat] 520 00:21:21,600 --> 00:21:24,000 >> and develop that tool out. So you know 521 00:21:24,000 --> 00:21:25,520 division or someone else is doing that. 522 00:21:25,520 --> 00:21:27,360 This is that's the beauty of segregating 523 00:21:27,360 --> 00:21:29,760 these things is we can be more. Um, one 524 00:21:29,760 --> 00:21:31,120 thing I actually did just think of that 525 00:21:31,120 --> 00:21:33,039 I would like to update on that may be 526 00:21:33,039 --> 00:21:34,559 something we need to discuss later is, 527 00:21:34,559 --> 00:21:37,280 you know, we are working through the New 528 00:21:37,280 --> 00:21:38,640 Ballet Basin project. That's something 529 00:21:38,640 --> 00:21:40,320 that's still chugging forward and we're 530 00:21:40,320 --> 00:21:41,919 trying to convene all of our agency 531 00:21:41,919 --> 00:21:43,760 partners to, you know, help and work 532 00:21:43,760 --> 00:21:45,600 through, you know, collecting data and 533 00:21:45,600 --> 00:21:48,080 making sure that's a good project. That 534 00:21:48,080 --> 00:21:50,480 will likely have some solidity impacts, 535 00:21:50,480 --> 00:21:51,919 you know, based on what comes back to 536 00:21:51,919 --> 00:21:54,159 the lake and also, you know, any water 537 00:21:54,159 --> 00:21:56,080 source we get is going to change these, 538 00:21:56,080 --> 00:21:57,360 you know, dynamics and it's going to 539 00:21:57,360 --> 00:21:58,960 increase the need to to measure. And I 540 00:21:58,960 --> 00:22:00,159 think we're going to, you know, work 541 00:22:00,159 --> 00:22:01,919 with USGS and others to make sure that 542 00:22:01,919 --> 00:22:04,799 we're measuring inflows and chemistry of 543 00:22:04,799 --> 00:22:06,240 water that comes out of that. And then, 544 00:22:06,240 --> 00:22:09,280 uh, and then the other one is, uh, you 545 00:22:09,280 --> 00:22:11,600 know, our purchase of the US Magnesium 546 00:22:11,600 --> 00:22:14,000 facility. We also have all of the water 547 00:22:14,000 --> 00:22:17,919 that gets stopped in Stanbury Bay that 548 00:22:17,919 --> 00:22:21,120 we think will, you know, amount to a 549 00:22:21,120 --> 00:22:23,200 pretty significant amount of water, but 550 00:22:23,200 --> 00:22:25,440 also there's a ton of accumulated salts 551 00:22:25,440 --> 00:22:27,600 in Stanbury Bay. And so we're working 552 00:22:27,600 --> 00:22:29,039 through different angles to figure out 553 00:22:29,039 --> 00:22:31,120 just exactly how this will work out, how 554 00:22:31,120 --> 00:22:32,640 we could potentially return water that 555 00:22:32,640 --> 00:22:34,400 would otherwise make it through Stanbury 556 00:22:34,400 --> 00:22:37,200 Bay to get to Gritzell Lake. Um we did 557 00:22:37,200 --> 00:22:39,679 get I think it's finished. Well, I guess 558 00:22:39,679 --> 00:22:40,880 we'll see. It's we don't have it till 559 00:22:40,880 --> 00:22:41,840 the checks in our hand, but I think 560 00:22:41,840 --> 00:22:44,640 we've got a $4.5 million appropriation 561 00:22:44,640 --> 00:22:47,200 from Congress to uh implement this 562 00:22:47,200 --> 00:22:50,000 project. So, we're hoping that we can 563 00:22:50,000 --> 00:22:52,240 start to do some of this work and and 564 00:22:52,240 --> 00:22:54,320 get, you know, find another source of 565 00:22:54,320 --> 00:22:57,360 water that doesn't have intermediable 566 00:22:57,360 --> 00:23:00,159 break. So, it would lots of cool stuff 567 00:23:00,159 --> 00:23:03,200 happen out there. 568 00:23:03,200 --> 00:23:04,400 >> Yeah, there's a lot going on. 569 00:23:04,400 --> 00:23:06,240 >> Yeah. 570 00:23:06,240 --> 00:23:09,919 >> And then Jim from DW updates any 571 00:23:09,919 --> 00:23:12,240 updates? Uh no nothing [clears throat] 572 00:23:12,240 --> 00:23:13,919 different uh than you know just to 573 00:23:13,919 --> 00:23:15,840 reiterate there were some questions 574 00:23:15,840 --> 00:23:18,640 about our rule and how this would apply 575 00:23:18,640 --> 00:23:22,400 um with increasing salinity and um just 576 00:23:22,400 --> 00:23:24,559 I'm not sure exactly what I informed 577 00:23:24,559 --> 00:23:26,720 this group on but um we did have some 578 00:23:26,720 --> 00:23:28,640 conversations [clears throat] 579 00:23:28,640 --> 00:23:31,120 and uh you know our rule is kind of what 580 00:23:31,120 --> 00:23:33,600 it is if if the lake does reach 150 581 00:23:33,600 --> 00:23:37,840 there is a um you know a limit to um 582 00:23:37,840 --> 00:23:40,640 allowing additional discharges to the 583 00:23:40,640 --> 00:23:43,840 So, um, you know, it's our hope is that, 584 00:23:43,840 --> 00:23:46,000 you know, management is careful not to 585 00:23:46,000 --> 00:23:47,600 do that so that we're not put in that 586 00:23:47,600 --> 00:23:50,799 position. Um, but, uh, other than 587 00:23:50,799 --> 00:23:53,679 flexibilities, there really aren't any, 588 00:23:53,679 --> 00:23:56,640 um, with the exception of some of the 589 00:23:56,640 --> 00:23:59,039 built-in um, offramps for dimminimous 590 00:23:59,039 --> 00:24:02,240 discharges. So, if there's any questions 591 00:24:02,240 --> 00:24:06,789 about that. 592 00:24:06,799 --> 00:24:11,120 » Any questions for them? Um, 593 00:24:11,120 --> 00:24:14,000 if not, I think we can move on to 594 00:24:14,000 --> 00:24:15,360 proceeding. 595 00:24:15,360 --> 00:24:16,159 >> Cool. 596 00:24:16,159 --> 00:24:18,559 >> Ryan's gonna give us the lowdown on 597 00:24:18,559 --> 00:24:20,640 recent 598 00:24:20,640 --> 00:24:22,799 monitoring, recent observations since 599 00:24:22,799 --> 00:24:31,350 the BM has been forwarded. 600 00:24:31,360 --> 00:24:34,411 All 601 00:24:34,421 --> 00:24:38,630 » [clears throat] 602 00:24:38,640 --> 00:24:40,159 » right, this is what we've all been 603 00:24:40,159 --> 00:24:43,840 waiting for. So, um, next slide, please. 604 00:24:43,840 --> 00:24:45,520 All right, before we get into the data, 605 00:24:45,520 --> 00:24:48,799 let's just review um, uh, the setup at 606 00:24:48,799 --> 00:24:51,440 the at the new brereech. Okay, so we 607 00:24:51,440 --> 00:24:53,039 have the south side of the lake. This is 608 00:24:53,039 --> 00:24:54,559 the causeway bridge here. So, we're 609 00:24:54,559 --> 00:24:56,240 looking at a cross-section, the bridge 610 00:24:56,240 --> 00:24:59,279 deck, south side of the lake on the left 611 00:24:59,279 --> 00:25:01,200 side, right, north side of the lake to 612 00:25:01,200 --> 00:25:03,919 the right. Um, [clears throat] we're 613 00:25:03,919 --> 00:25:05,520 indicating the lake bottom with this 614 00:25:05,520 --> 00:25:07,840 brown color. Um, and the burm is 615 00:25:07,840 --> 00:25:10,799 indicated here, uh, on the north side of 616 00:25:10,799 --> 00:25:12,880 the bridge. And then we have an 617 00:25:12,880 --> 00:25:15,840 uplooking acoustic Doppler um current 618 00:25:15,840 --> 00:25:19,200 profiler um mounted to an anchor and 619 00:25:19,200 --> 00:25:21,520 it's measuring velocities at 10 620 00:25:21,520 --> 00:25:23,760 different cells or 10 depths throughout 621 00:25:23,760 --> 00:25:26,240 the water column. So cell one is close 622 00:25:26,240 --> 00:25:29,520 to the bottom and cell 10 is is the 623 00:25:29,520 --> 00:25:31,360 shallowest depth. Keep that in mind as 624 00:25:31,360 --> 00:25:34,880 we as we look at data um going forward. 625 00:25:34,880 --> 00:25:37,840 So the cell width, so [snorts] this it's 626 00:25:37,840 --> 00:25:39,200 measuring velocities in the center of 627 00:25:39,200 --> 00:25:41,440 these cells and the width of each cell 628 00:25:41,440 --> 00:25:45,279 is 1.3 ft. We're making measurements um 629 00:25:45,279 --> 00:25:46,720 calculating measurements every 15 630 00:25:46,720 --> 00:25:48,080 minutes and there's a five minute 631 00:25:48,080 --> 00:25:50,240 averaging interval and these data are 632 00:25:50,240 --> 00:25:52,720 available to you via uh the natural 633 00:25:52,720 --> 00:25:55,120 water dashboard. Um it's updated about 634 00:25:55,120 --> 00:25:59,200 hourly um uh there. Uh so the station 635 00:25:59,200 --> 00:26:02,320 number associated with that data is 100 636 00:26:02,320 --> 00:26:04,080 125. 637 00:26:04,080 --> 00:26:06,720 Okay. So, just kind of keep this um 638 00:26:06,720 --> 00:26:08,320 schematic in mind and we all know that 639 00:26:08,320 --> 00:26:10,960 we have south to north flow um 640 00:26:10,960 --> 00:26:14,159 overalking the uh north to south flow. 641 00:26:14,159 --> 00:26:15,919 So, everybody's clear on that. All 642 00:26:15,919 --> 00:26:19,360 right, let's let's move into um data 643 00:26:19,360 --> 00:26:21,840 from that uplooking velocity meter. So, 644 00:26:21,840 --> 00:26:22,960 on [clears throat] the y- axis we have 645 00:26:22,960 --> 00:26:25,520 velocity and feet per second. Here's the 646 00:26:25,520 --> 00:26:27,360 zero mark. This is 3 feet per second at 647 00:26:27,360 --> 00:26:28,880 the top. It's negative five feet per 648 00:26:28,880 --> 00:26:30,880 second at the bottom of the plot. and 649 00:26:30,880 --> 00:26:34,159 we're showing data from July 2000 uh or 650 00:26:34,159 --> 00:26:37,279 excuse me July 9th uh [clears throat] 651 00:26:37,279 --> 00:26:39,039 2026 through the through the current 652 00:26:39,039 --> 00:26:42,880 period and I've indicated where you see 653 00:26:42,880 --> 00:26:44,720 a big difference in the data leading 654 00:26:44,720 --> 00:26:47,919 into the burn modification. So prior to 655 00:26:47,919 --> 00:26:50,640 burn modification you had the cells 656 00:26:50,640 --> 00:26:51,840 these [clears throat] cells in the in 657 00:26:51,840 --> 00:26:54,480 the positive territory above the zero 658 00:26:54,480 --> 00:26:57,520 mark uh on the plot these are the south 659 00:26:57,520 --> 00:26:59,120 and north flows. Okay, so those 660 00:26:59,120 --> 00:27:02,080 velocities are hug hugging around 0.5 661 00:27:02,080 --> 00:27:03,840 feet per second. [clears throat] The 662 00:27:03,840 --> 00:27:05,679 velocities that are measured closer to 663 00:27:05,679 --> 00:27:08,000 the bottom, they're hugging around the 664 00:27:08,000 --> 00:27:10,400 zero foot per second or slightly 665 00:27:10,400 --> 00:27:13,279 negative. Uh and then we modify the burn 666 00:27:13,279 --> 00:27:15,279 and it's completed sometime on the on 667 00:27:15,279 --> 00:27:18,000 the 16th. I think the burn modification 668 00:27:18,000 --> 00:27:20,000 complete. But anyway, you can we can 669 00:27:20,000 --> 00:27:21,679 even see when they started working on it 670 00:27:21,679 --> 00:27:24,240 in this data set, we see those shallower 671 00:27:24,240 --> 00:27:27,200 velocities jump up to over, you know, 672 00:27:27,200 --> 00:27:29,760 between one and two feet per second and 673 00:27:29,760 --> 00:27:31,600 we see some of these velocities that are 674 00:27:31,600 --> 00:27:34,960 measured closer to the bottom going to [clears throat] larger negative 675 00:27:34,960 --> 00:27:38,960 values around one foot. Okay, so the big 676 00:27:38,960 --> 00:27:41,600 picture with this data is that when we 677 00:27:41,600 --> 00:27:43,279 modified this BM when it was lowered in 678 00:27:43,279 --> 00:27:45,039 4183, 679 00:27:45,039 --> 00:27:46,799 south to north velocities increased a 680 00:27:46,799 --> 00:27:50,240 little bit and north to south velocities 681 00:27:50,240 --> 00:27:52,240 increased a little bit. Okay. Well, that 682 00:27:52,240 --> 00:27:54,080 was the intent of this, right? Was to 683 00:27:54,080 --> 00:27:56,399 get more north to south water to the 684 00:27:56,399 --> 00:28:00,080 south of the of the lake. And we we see 685 00:28:00,080 --> 00:28:02,640 evidence that that is happening by these 686 00:28:02,640 --> 00:28:05,200 more negative north south velocities 687 00:28:05,200 --> 00:28:07,760 measured in those deeper cells. Does 688 00:28:07,760 --> 00:28:10,640 that make sense to everybody? Okay, 689 00:28:10,640 --> 00:28:13,279 that's observation one. [clears throat] 690 00:28:13,279 --> 00:28:16,240 Um observation two, we still see these 691 00:28:16,240 --> 00:28:19,039 big um 692 00:28:19,039 --> 00:28:20,880 spikes in this data that are happening 693 00:28:20,880 --> 00:28:24,399 periodically. So after burn modification 694 00:28:24,399 --> 00:28:26,559 the velocity response to wind events is 695 00:28:26,559 --> 00:28:29,039 still very evident in this data. These 696 00:28:29,039 --> 00:28:31,840 are the result of wind events causing in 697 00:28:31,840 --> 00:28:35,120 this case uh we had a wind event blowing 698 00:28:35,120 --> 00:28:38,799 um out of the north and all the and at 699 00:28:38,799 --> 00:28:41,039 some point the the dynamics of that at 700 00:28:41,039 --> 00:28:43,520 that causeway changed so that north arm 701 00:28:43,520 --> 00:28:45,440 water was all north arm water starting 702 00:28:45,440 --> 00:28:48,159 to move south and so all the velocities 703 00:28:48,159 --> 00:28:48,960 measured throughout [clears throat] the 704 00:28:48,960 --> 00:28:51,360 water column are dipping down into this 705 00:28:51,360 --> 00:28:54,559 negative territory. A negative velocity 706 00:28:54,559 --> 00:28:57,120 is a north south direction. Does that 707 00:28:57,120 --> 00:29:00,399 make sense? Okay. And we see many wind 708 00:29:00,399 --> 00:29:02,720 events impacting the data through this 709 00:29:02,720 --> 00:29:04,320 period, including a wind [clears throat] 710 00:29:04,320 --> 00:29:07,600 event um that was pushing uh water into 711 00:29:07,600 --> 00:29:09,919 very positive velocities 712 00:29:09,919 --> 00:29:11,919 uh south and north flows. So almost 713 00:29:11,919 --> 00:29:16,399 uniform flows south to north. Um so 714 00:29:16,399 --> 00:29:18,320 the entire water column then starts to 715 00:29:18,320 --> 00:29:21,440 shift um and blows uh to the south from 716 00:29:21,440 --> 00:29:23,039 the north to the south in an event like 717 00:29:23,039 --> 00:29:25,120 this. And it's just vice versa on an 718 00:29:25,120 --> 00:29:28,399 event like this. Does that make sense? 719 00:29:28,399 --> 00:29:31,520 Okay, we saw these wind events impacting 720 00:29:31,520 --> 00:29:32,399 the velocity [clears throat] 721 00:29:32,399 --> 00:29:35,600 data set here previously. So, we still 722 00:29:35,600 --> 00:29:37,760 see that. 723 00:29:37,760 --> 00:29:40,799 Next slide. All right. Now, let's just 724 00:29:40,799 --> 00:29:44,559 zoom in on um a two-day period in that 725 00:29:44,559 --> 00:29:48,559 data set. So from July 18th to July 20th 726 00:29:48,559 --> 00:29:51,840 and let's take a really close look at 727 00:29:51,840 --> 00:29:55,279 the complex nature of these uh velocity 728 00:29:55,279 --> 00:29:56,480 measurements throughout the water 729 00:29:56,480 --> 00:29:59,279 column. So these uh numbers well first 730 00:29:59,279 --> 00:30:01,200 of all the zero velocity line is 731 00:30:01,200 --> 00:30:03,039 indicated with the bold black line. 732 00:30:03,039 --> 00:30:06,080 Anything above is a positive velocity 733 00:30:06,080 --> 00:30:08,799 south to north. Anything below is a 734 00:30:08,799 --> 00:30:11,520 negative velocity north south. All 735 00:30:11,520 --> 00:30:15,520 right. Um the blue line in indicated 736 00:30:15,520 --> 00:30:17,600 with the number one here that's that 737 00:30:17,600 --> 00:30:19,919 first cell measured by that uplooker. 738 00:30:19,919 --> 00:30:23,279 That's the deepest cell that we measure. 739 00:30:23,279 --> 00:30:26,640 So that velocity at that blue line or 740 00:30:26,640 --> 00:30:28,480 represented by the blue line is hugging 741 00:30:28,480 --> 00:30:32,240 is close to this zero um mark zero line 742 00:30:32,240 --> 00:30:34,399 on this plot. Now working our way up the 743 00:30:34,399 --> 00:30:37,039 water column [clears throat] as we step 744 00:30:37,039 --> 00:30:41,440 up um into uh the next layer of water. 745 00:30:41,440 --> 00:30:44,799 uh above layer 1, the velocities are 746 00:30:44,799 --> 00:30:47,200 slightly more negative. So that water is 747 00:30:47,200 --> 00:30:49,679 moving a little bit faster 748 00:30:49,679 --> 00:30:52,880 uh heading to in the north direction. As 749 00:30:52,880 --> 00:30:56,240 we go further up, the water velocities 750 00:30:56,240 --> 00:30:57,840 heading in the north direction are even 751 00:30:57,840 --> 00:31:00,480 stronger, higher velocities. 752 00:31:00,480 --> 00:31:03,200 Okay, so close to the uplooker, the 753 00:31:03,200 --> 00:31:05,039 north to south velocities are slow and 754 00:31:05,039 --> 00:31:06,880 as we work our way up, those north south 755 00:31:06,880 --> 00:31:11,360 velocities start to pick up. All right, 756 00:31:11,360 --> 00:31:13,360 here's cell four. So, [clears throat] 757 00:31:13,360 --> 00:31:14,960 working our way up the water column. 758 00:31:14,960 --> 00:31:17,120 Still in the negative territory here. 759 00:31:17,120 --> 00:31:18,799 Pretty strong negative velocities at 760 00:31:18,799 --> 00:31:21,039 time, but pretty big fluctuation. This 761 00:31:21,039 --> 00:31:23,279 is four up here and this is four down 762 00:31:23,279 --> 00:31:25,520 there. We're starting to get into the 763 00:31:25,520 --> 00:31:28,080 transitions though where we're getting 764 00:31:28,080 --> 00:31:31,039 out of just that north highly brine 765 00:31:31,039 --> 00:31:32,880 water and we're working our way up the 766 00:31:32,880 --> 00:31:35,440 water column into the south water. So by 767 00:31:35,440 --> 00:31:38,240 the time we get to cell five, it's way 768 00:31:38,240 --> 00:31:40,179 above the zero line and it can 769 00:31:40,179 --> 00:31:41,840 [clears throat] come significantly below 770 00:31:41,840 --> 00:31:43,679 the zero line. So we're in that 771 00:31:43,679 --> 00:31:46,960 transition zone, okay? Where the north 772 00:31:46,960 --> 00:31:48,720 to south water, you know, it's just 773 00:31:48,720 --> 00:31:50,559 cruising over each other. But this cell 774 00:31:50,559 --> 00:31:53,519 five, four, and five, mostly five in 775 00:31:53,519 --> 00:31:55,600 that transition zone. That's at about 776 00:31:55,600 --> 00:31:57,200 4185, 777 00:31:57,200 --> 00:32:01,039 by the way, in terms of the the data, 778 00:32:01,039 --> 00:32:03,200 the Great Salt Lake elevation data that 779 00:32:03,200 --> 00:32:05,039 we're all familiar with. Now we work our 780 00:32:05,039 --> 00:32:07,840 way up the water column. Cell six, uh, 781 00:32:07,840 --> 00:32:09,760 these are strongly positive velocities. 782 00:32:09,760 --> 00:32:13,279 That's 08 feet per second. And then, you 783 00:32:13,279 --> 00:32:16,640 know, uh, cell, 784 00:32:16,640 --> 00:32:19,840 uh, stronger velocity still. Cell nine 785 00:32:19,840 --> 00:32:22,720 or eight, stronger velocity. And then as 786 00:32:22,720 --> 00:32:26,000 we get close to the top of the lake 787 00:32:26,000 --> 00:32:28,399 where we're measuring velocities, cell 9 788 00:32:28,399 --> 00:32:29,679 and 10, the velocities are actually a 789 00:32:29,679 --> 00:32:31,360 little bit a little bit lower, at least 790 00:32:31,360 --> 00:32:34,080 in this little slice we're talking about 791 00:32:34,080 --> 00:32:36,880 right here. The point here is it's a 792 00:32:36,880 --> 00:32:42,080 complex velocity profile. Um, but in 793 00:32:42,080 --> 00:32:45,200 general, we're uh accomplishing what we 794 00:32:45,200 --> 00:32:47,360 wanted to accomplish with with this uh 795 00:32:47,360 --> 00:32:49,279 BM obation. We're seeing stronger 796 00:32:49,279 --> 00:32:52,080 velocities in the north south direction. 797 00:32:52,080 --> 00:32:54,799 Pulse burner modification. 798 00:32:54,799 --> 00:32:55,519 >> Question. 799 00:32:55,519 --> 00:32:56,880 >> What was the elevation difference 800 00:32:56,880 --> 00:32:58,240 between each of those different 801 00:32:58,240 --> 00:32:59,760 profiles? You say 802 00:32:59,760 --> 00:33:03,440 >> 1.3 ft. Well, 1.3 ft is the cell width. 803 00:33:03,440 --> 00:33:06,000 Yeah, it's 1.3 ft distance between them. 804 00:33:06,000 --> 00:33:07,919 >> Yeah. 805 00:33:07,919 --> 00:33:10,960 So where So just 806 00:33:10,960 --> 00:33:13,039 to make sure I'm understanding the those 807 00:33:13,039 --> 00:33:15,360 one, two, three, and four would be 808 00:33:15,360 --> 00:33:17,200 representative of like five feet of 809 00:33:17,200 --> 00:33:19,760 north to south flows. 810 00:33:19,760 --> 00:33:22,399 >> Yeah. Yeah. And that's at that's at 811 00:33:22,399 --> 00:33:23,360 depth. 812 00:33:23,360 --> 00:33:23,840 >> Yep. 813 00:33:23,840 --> 00:33:25,679 >> And we only had during this time period, 814 00:33:25,679 --> 00:33:27,519 we only had like less than half of a 815 00:33:27,519 --> 00:33:29,760 foot of difference. 816 00:33:29,760 --> 00:33:31,760 >> Less than a half a foot between that 817 00:33:31,760 --> 00:33:33,360 difference north and south. 818 00:33:33,360 --> 00:33:35,360 >> Yeah. I haven't looked into that in 819 00:33:35,360 --> 00:33:38,399 detail. So It's just it's interesting 820 00:33:38,399 --> 00:33:39,760 because I think one of the things that 821 00:33:39,760 --> 00:33:42,000 we were working off of back when we were 822 00:33:42,000 --> 00:33:44,640 looking at like you know how when we can 823 00:33:44,640 --> 00:33:47,039 see north to south flows is like you 824 00:33:47,039 --> 00:33:48,960 know this much of a head difference you 825 00:33:48,960 --> 00:33:50,320 can see that north to south flow. It's 826 00:33:50,320 --> 00:33:52,080 just interesting that we're seeing you 827 00:33:52,080 --> 00:33:55,840 know such an increase in that flow at 828 00:33:55,840 --> 00:33:57,120 those lower depths. I don't know if that 829 00:33:57,120 --> 00:33:59,200 matters or maybe the difference in head 830 00:33:59,200 --> 00:34:01,200 difference is what drives that but I 831 00:34:01,200 --> 00:34:02,159 think you know before when we were 832 00:34:02,159 --> 00:34:04,320 looking at things like you know siphons 833 00:34:04,320 --> 00:34:06,640 or you know other ways to do that I I 834 00:34:06,640 --> 00:34:07,760 recall that maybe there [snorts] was 835 00:34:07,760 --> 00:34:10,399 like a two or three feet of difference 836 00:34:10,399 --> 00:34:12,399 that could be 837 00:34:12,399 --> 00:34:13,760 worked into that but maybe I'm not 838 00:34:13,760 --> 00:34:16,320 thinking of that the right way. I I 839 00:34:16,320 --> 00:34:20,720 think right around 12 to 16 inches is 840 00:34:20,720 --> 00:34:24,639 kind of the if we're below that we see 841 00:34:24,639 --> 00:34:28,480 much more north water coming down. Um 842 00:34:28,480 --> 00:34:30,560 and so I think where we are with that 6 843 00:34:30,560 --> 00:34:35,440 in differential is probably the the most 844 00:34:35,440 --> 00:34:38,240 north to south flow that we see. 845 00:34:38,240 --> 00:34:39,919 >> Um 846 00:34:39,919 --> 00:34:42,480 because now the density is much more 847 00:34:42,480 --> 00:34:44,560 important. We don't have enough head 848 00:34:44,560 --> 00:34:47,119 differential to push water north, but 849 00:34:47,119 --> 00:34:49,440 you get more differential now that south 850 00:34:49,440 --> 00:34:54,704 to north becomes more important. 851 00:34:54,714 --> 00:34:56,159 [clears throat] 852 00:34:56,159 --> 00:34:58,320 >> Okay. Well, uh these these uplookers, 853 00:34:58,320 --> 00:35:00,079 this technology is it's been around a 854 00:35:00,079 --> 00:35:02,000 while and I still I find it very 855 00:35:02,000 --> 00:35:08,320 remarkable technology and um so this gives us some pretty precise uh 856 00:35:08,320 --> 00:35:09,760 information on on what's happening with 857 00:35:09,760 --> 00:35:12,720 the flow dynamics. You know, I one one 858 00:35:12,720 --> 00:35:16,720 uh thing to keep in mind that cell one. 859 00:35:16,720 --> 00:35:18,320 So, we have the uplooker. It's sitting 860 00:35:18,320 --> 00:35:21,359 on an anchor that's about a foot thick. 861 00:35:21,359 --> 00:35:23,200 And then there's the uplooker sitting on 862 00:35:23,200 --> 00:35:24,880 top of the anchor. And then there's a 863 00:35:24,880 --> 00:35:27,520 blanking distance where the the uplooker 864 00:35:27,520 --> 00:35:28,880 can't measure velocity. There's some 865 00:35:28,880 --> 00:35:30,400 distance right above the sensor where it 866 00:35:30,400 --> 00:35:32,079 can't measure velocity. And then we hit 867 00:35:32,079 --> 00:35:38,310 cell one. So, we've had a distance of 868 00:35:38,320 --> 00:35:41,520 from here. Yeah, this blanks space, you 869 00:35:41,520 --> 00:35:44,000 know, from the blue up to uh the number 870 00:35:44,000 --> 00:35:46,400 one, that's a blanking distance where we 871 00:35:46,400 --> 00:35:50,160 don't have data. Um, let's go back to 872 00:35:50,160 --> 00:35:54,000 the velocity slide. But even with that, 873 00:35:54,000 --> 00:35:56,000 we know that that cell one that where we 874 00:35:56,000 --> 00:35:58,400 are getting data, which is can be almost 875 00:35:58,400 --> 00:36:00,560 like potentially three feet above the 876 00:36:00,560 --> 00:36:03,920 bottom, those velocities in cell one are 877 00:36:03,920 --> 00:36:07,119 really low, really low. But we have a 878 00:36:07,119 --> 00:36:08,560 lot of uncertainty. what happens below 879 00:36:08,560 --> 00:36:10,800 cell one because we see these really 880 00:36:10,800 --> 00:36:13,200 velocity really low velocities in cell 881 00:36:13,200 --> 00:36:21,119 one. Um we think that water right now is not moving quickly. It's almost like 882 00:36:21,119 --> 00:36:26,960 there's a um the water's coming over the modified BM and just kind of 883 00:36:26,960 --> 00:36:30,000 shooting through represented by these 884 00:36:30,000 --> 00:36:33,599 Let's go to the velocity slide. 885 00:36:33,599 --> 00:36:35,359 represented by these higher velocities 886 00:36:35,359 --> 00:36:37,119 here. 887 00:36:37,119 --> 00:36:39,680 But the water um that's deeper than 888 00:36:39,680 --> 00:36:42,800 cells three and four is relatively 889 00:36:42,800 --> 00:36:45,040 quiet. Does that make sense? 890 00:36:45,040 --> 00:36:47,680 >> Yeah. So in that um kind of redder area 891 00:36:47,680 --> 00:36:50,720 right at the bottom, Mike Freeman is his 892 00:36:50,720 --> 00:36:52,320 observations are that that's relative 893 00:36:52,320 --> 00:36:54,320 like a stagnant pool and it's actually 894 00:36:54,320 --> 00:36:56,079 advantageous that we have our instrument 895 00:36:56,079 --> 00:36:58,240 where it is because just that's pretty 896 00:36:58,240 --> 00:37:05,990 quiet water right there. 897 00:37:06,000 --> 00:37:09,520 Okay. Um next slide. All right. So, 898 00:37:09,520 --> 00:37:10,960 let's look at the actual field 899 00:37:10,960 --> 00:37:12,240 measurements of discharge that we're 900 00:37:12,240 --> 00:37:14,720 making with the downlooking ABC mounted 901 00:37:14,720 --> 00:37:17,760 to a little boat that we can tow across. 902 00:37:17,760 --> 00:37:20,480 Um, so we have discharge in cubic feet 903 00:37:20,480 --> 00:37:23,040 per second on the y- axis going from 904 00:37:23,040 --> 00:37:25,920 about 300 cfs at the bottom to 900 cfs 905 00:37:25,920 --> 00:37:27,599 at the top showing data from October 906 00:37:27,599 --> 00:37:29,760 1st, 2025 out [clears throat] to 907 00:37:29,760 --> 00:37:31,599 yesterday. So, these are field 908 00:37:31,599 --> 00:37:33,200 measurements of south to north flow 909 00:37:33,200 --> 00:37:35,859 shown on this plot. Um let's 910 00:37:35,859 --> 00:37:37,040 [clears throat] just kind of get over 911 00:37:37,040 --> 00:37:38,320 here to the right side of the plot where 912 00:37:38,320 --> 00:37:41,359 all the action is. Um the measurement 913 00:37:41,359 --> 00:37:43,359 made on July 10th just before the burm 914 00:37:43,359 --> 00:37:45,920 was lowered. So this is indicated of 915 00:37:45,920 --> 00:37:49,280 July 16th right when the burm was 916 00:37:49,280 --> 00:37:51,040 lowered. So that measurement just prior 917 00:37:51,040 --> 00:37:55,760 to that event was 500 cfs. July 17th the 918 00:37:55,760 --> 00:37:57,839 day after the burn modification was 919 00:37:57,839 --> 00:38:03,119 completed uh we measured 376 cfs. July 920 00:38:03,119 --> 00:38:06,880 24th back up to 928 cfs, but there was a 921 00:38:06,880 --> 00:38:09,040 south to north wind event. So water's 922 00:38:09,040 --> 00:38:10,880 pushing or wind is pushing water from 923 00:38:10,880 --> 00:38:13,119 the south to the north. Uh causing a 924 00:38:13,119 --> 00:38:15,839 higher discharge on that day, August 925 00:38:15,839 --> 00:38:19,119 5th, couple days ago, very quiet 926 00:38:19,119 --> 00:38:21,839 conditions. Um or was that yesterday? 927 00:38:21,839 --> 00:38:24,400 Thank you. Yesterday, quiet conditions, 928 00:38:24,400 --> 00:38:27,040 the discharge measurement came in at 542 929 00:38:27,040 --> 00:38:30,000 cfs. So, just kind of looking at these 930 00:38:30,000 --> 00:38:32,880 versus these, 931 00:38:32,880 --> 00:38:35,680 not a not a huge dramatic change. Um, 932 00:38:35,680 --> 00:38:36,960 you know, just kind of order of 933 00:38:36,960 --> 00:38:40,320 magnitude. Uh, but right now we're about 934 00:38:40,320 --> 00:38:44,240 540 CFS just as of yesterday. South to 935 00:38:44,240 --> 00:38:47,760 north. Next. 936 00:38:47,760 --> 00:38:51,520 All right. North to south. Um, same uh 937 00:38:51,520 --> 00:38:53,760 axes definitions. 938 00:38:53,760 --> 00:38:56,560 um other than the this is a zero at the 939 00:38:56,560 --> 00:38:58,880 bottom and this is 200 CFS towards the 940 00:38:58,880 --> 00:39:01,680 top of the plot and let's just go right 941 00:39:01,680 --> 00:39:03,040 to the right side of the plot get into 942 00:39:03,040 --> 00:39:06,560 the action on July 10th we measured 23 943 00:39:06,560 --> 00:39:08,960 CFS remember there's higher uncertainty 944 00:39:08,960 --> 00:39:10,400 with respect to these north and south 945 00:39:10,400 --> 00:39:12,000 numbers part of it's due to the blanking 946 00:39:12,000 --> 00:39:15,920 distance we just talked about but there are some other factors at play as 947 00:39:15,920 --> 00:39:21,839 well um on July 17th the day after 948 00:39:21,839 --> 00:39:28,000 84 CFS s not a huge jump. Um on July 949 00:39:28,000 --> 00:39:32,320 24th, 16 CFS back down, but this July 950 00:39:32,320 --> 00:39:34,880 24th is the when we had that significant 951 00:39:34,880 --> 00:39:38,240 south um southern wind south to north 952 00:39:38,240 --> 00:39:47,040 wind event. It's not surprising that value is suppressed because of that wind event. August 5th, this is 953 00:39:47,040 --> 00:39:49,599 quiescent conditions. We feel pretty 954 00:39:49,599 --> 00:39:51,440 good. We feel like the uncertainty 955 00:39:51,440 --> 00:39:53,200 related to this August 5th measurement 956 00:39:53,200 --> 00:39:56,079 is is less than the uncertainty related 957 00:39:56,079 --> 00:39:58,960 to July 17th and July 24th. August 5th 958 00:39:58,960 --> 00:40:03,280 came in at 233 CFS. All right, this is 959 00:40:03,280 --> 00:40:06,480 great. This is a big jump from where we 960 00:40:06,480 --> 00:40:10,400 were. So, uh I think the story here is 961 00:40:10,400 --> 00:40:12,480 right now it's looking like this B 962 00:40:12,480 --> 00:40:15,119 modification is doing what we wanted it 963 00:40:15,119 --> 00:40:17,520 to do. flows have increased 964 00:40:17,520 --> 00:40:20,240 significantly from the north direction 965 00:40:20,240 --> 00:40:22,640 towards the south moving salt moving 966 00:40:22,640 --> 00:40:25,119 nutrients um to the south and I think 967 00:40:25,119 --> 00:40:28,720 that was the objective right all right 968 00:40:28,720 --> 00:40:29,680 so [clears throat] 969 00:40:29,680 --> 00:40:31,920 the uncertainty that I keep I mentioned 970 00:40:31,920 --> 00:40:33,359 it last meeting with these north to 971 00:40:33,359 --> 00:40:36,800 south flows um we're going to have much 972 00:40:36,800 --> 00:40:38,560 more to say about this in the coming 973 00:40:38,560 --> 00:40:41,119 months um we're doing a lot of work to 974 00:40:41,119 --> 00:40:45,920 try to pin this down but for Now, the 975 00:40:45,920 --> 00:40:47,440 uncertainty is higher for these north to 976 00:40:47,440 --> 00:40:51,839 south values um relative to the south to 977 00:40:51,839 --> 00:40:54,079 north values on the previous plot, but 978 00:40:54,079 --> 00:40:55,359 we're working through it. And we think 979 00:40:55,359 --> 00:40:58,160 this this August 5th measurement is is 980 00:40:58,160 --> 00:40:59,920 the better of the the three we've made 981 00:40:59,920 --> 00:41:03,280 since the burn was was 982 00:41:03,280 --> 00:41:07,990 that 983 00:41:08,000 --> 00:41:13,670 a question? 984 00:41:13,680 --> 00:41:15,280 Okay, great. 985 00:41:15,280 --> 00:41:19,040 >> And then I just threw in um salt fluxes 986 00:41:19,040 --> 00:41:20,640 like what this would mean for salt flux. 987 00:41:20,640 --> 00:41:24,000 So this the orange line here represents 988 00:41:24,000 --> 00:41:26,800 July 16th and then to the right of that 989 00:41:26,800 --> 00:41:28,720 represents the period where the BM is 990 00:41:28,720 --> 00:41:32,640 lowered to 4183. And um these I mean 991 00:41:32,640 --> 00:41:34,240 this is largely controlled by the 992 00:41:34,240 --> 00:41:36,640 discharge. So you see like these two 993 00:41:36,640 --> 00:41:38,800 we're still getting a lot of um net 994 00:41:38,800 --> 00:41:41,280 south to north transport of salt because 995 00:41:41,280 --> 00:41:43,920 those discharges were high. For this one 996 00:41:43,920 --> 00:41:45,599 we have most confidence in the discharge 997 00:41:45,599 --> 00:41:47,520 reading that was made yesterday. We're 998 00:41:47,520 --> 00:41:51,680 approaching kind of this um net zero 999 00:41:51,680 --> 00:41:54,240 flux and we'll be curious to see if this 1000 00:41:54,240 --> 00:41:56,480 we start trending into import territory 1001 00:41:56,480 --> 00:41:58,560 where we're starting to get salt from 1002 00:41:58,560 --> 00:42:01,040 the north to the south. So, we'll be 1003 00:42:01,040 --> 00:42:02,560 building out this data, but just 1004 00:42:02,560 --> 00:42:04,720 preliminarily, it does look like based 1005 00:42:04,720 --> 00:42:05,839 on the measurements that were made 1006 00:42:05,839 --> 00:42:08,240 yesterday, we're trending toward um 1007 00:42:08,240 --> 00:42:10,960 certainly lower net fluxes to the north 1008 00:42:10,960 --> 00:42:18,069 and potentially starting to import salt. 1009 00:42:18,079 --> 00:42:21,910 That's great. 1010 00:42:21,920 --> 00:42:26,720 Any any questions on that? 1011 00:42:26,720 --> 00:42:29,440 I was just curious, you know, with your 1012 00:42:29,440 --> 00:42:33,040 what you're seeing on the flux of south 1013 00:42:33,040 --> 00:42:35,200 to north and anticipating whether or not 1014 00:42:35,200 --> 00:42:36,720 we get a north to south or that just 1015 00:42:36,720 --> 00:42:39,599 that maybe stabilizes is that in line 1016 00:42:39,599 --> 00:42:41,359 with what you had anticipated would 1017 00:42:41,359 --> 00:42:43,680 happen with the you know the flourishing 1018 00:42:43,680 --> 00:42:45,040 that we're seeing from north to south 1019 00:42:45,040 --> 00:42:46,640 these reestablishment of those 1020 00:42:46,640 --> 00:42:49,359 >> close yeah it is that certainly that 1021 00:42:49,359 --> 00:42:53,040 trending down toward zero net flux of it 1022 00:42:53,040 --> 00:42:54,880 being equal is is what I would expect 1023 00:42:54,880 --> 00:42:57,119 because we removed a physical obstacle 1024 00:42:57,119 --> 00:42:58,960 and now we're getting a lot more salt in 1025 00:42:58,960 --> 00:43:02,079 from the north. Um, and so yeah, I would 1026 00:43:02,079 --> 00:43:04,079 expect, you know, us to be trending 1027 00:43:04,079 --> 00:43:07,920 toward net gaining of salt. It and 1028 00:43:07,920 --> 00:43:09,440 especially this time of year because 1029 00:43:09,440 --> 00:43:11,520 we're getting kind of the elevations to 1030 00:43:11,520 --> 00:43:13,760 be more equalized and as Jess said, it's 1031 00:43:13,760 --> 00:43:15,440 kind of dominated by density at that 1032 00:43:15,440 --> 00:43:17,920 point and you get flow from the north. 1033 00:43:17,920 --> 00:43:20,000 But I will say then I've been looking at 1034 00:43:20,000 --> 00:43:21,920 kind of how this current these current 1035 00:43:21,920 --> 00:43:25,359 measurements fit into like 2021 and 2022 1036 00:43:25,359 --> 00:43:27,119 and there's some variability in the 1037 00:43:27,119 --> 00:43:29,760 patterns we saw in 2021 and 2022 that I 1038 00:43:29,760 --> 00:43:32,800 can show you. Um that kind of 1039 00:43:32,800 --> 00:43:38,319 complicates the story because like and I can get into that but um it kind of 1040 00:43:38,319 --> 00:43:40,480 depends. It depends on water surface 1041 00:43:40,480 --> 00:43:41,920 elevation differences. It depends on the 1042 00:43:41,920 --> 00:43:44,000 density differential, but right now we 1043 00:43:44,000 --> 00:43:45,839 have a really large density differential 1044 00:43:45,839 --> 00:43:47,280 between the south and the north because 1045 00:43:47,280 --> 00:43:49,760 the salt is so much pressure. Um, so 1046 00:43:49,760 --> 00:43:51,920 that will also drive flow to the south 1047 00:43:51,920 --> 00:43:54,960 from the north. So yes, this is this is 1048 00:43:54,960 --> 00:43:57,200 what I would expect, but it it's kind of 1049 00:43:57,200 --> 00:43:59,119 a complicated 1050 00:43:59,119 --> 00:44:00,480 >> because I know you all were probably 1051 00:44:00,480 --> 00:44:03,520 thinking about like taking bets or doing 1052 00:44:03,520 --> 00:44:04,480 what the flows were going [laughter] to 1053 00:44:04,480 --> 00:44:07,760 be. Did you guys anticipate the any 1054 00:44:07,760 --> 00:44:09,599 certain flow with that lowering or did 1055 00:44:09,599 --> 00:44:12,240 you was it what you expected. 1056 00:44:12,240 --> 00:44:15,040 >> No, I mean I hadn't 1057 00:44:15,040 --> 00:44:19,510 >> didn't have an office pool. 1058 00:44:19,520 --> 00:44:22,630 » Guess 1059 00:44:22,640 --> 00:44:25,829 we 1060 00:44:25,839 --> 00:44:27,200 can ask a question about this. I mean, 1061 00:44:27,200 --> 00:44:28,960 even if it was at net zero, you're still 1062 00:44:28,960 --> 00:44:31,440 exporting more volumetric water. So, you 1063 00:44:31,440 --> 00:44:34,160 would still expect concentrations to, 1064 00:44:34,160 --> 00:44:36,319 you know, you just had a net was at net 1065 00:44:36,319 --> 00:44:38,240 zero in terms of mass exchange, but 1066 00:44:38,240 --> 00:44:40,720 you're still exchanging water. expect 1067 00:44:40,720 --> 00:44:42,400 concentrations to shift 1068 00:44:42,400 --> 00:44:43,200 >> in the southire 1069 00:44:43,200 --> 00:44:46,160 >> in both arms I guess because you're moving 1070 00:44:46,160 --> 00:44:46,880 >> water fast. 1071 00:44:46,880 --> 00:44:49,599 >> Yeah. Yep. 1072 00:44:49,599 --> 00:44:50,720 So Christine, 1073 00:44:50,720 --> 00:44:51,040 >> yeah, 1074 00:44:51,040 --> 00:44:53,760 >> when you say the the trend is a downward 1075 00:44:53,760 --> 00:44:55,280 trend, but then what are the factors 1076 00:44:55,280 --> 00:44:56,640 that would, 1077 00:44:56,640 --> 00:44:59,119 >> you know, allow that trend to continue? 1078 00:44:59,119 --> 00:45:01,040 Is it I mean, obviously the head 1079 00:45:01,040 --> 00:45:02,560 difference is one of them, but if we're 1080 00:45:02,560 --> 00:45:04,960 getting to already close to that minimum 1081 00:45:04,960 --> 00:45:06,400 head difference, what other factors 1082 00:45:06,400 --> 00:45:10,880 would still um have that trend continue? 1083 00:45:10,880 --> 00:45:12,720 >> That's a good question. I don't know. I 1084 00:45:12,720 --> 00:45:15,440 think really just Yeah, you're right. 1085 00:45:15,440 --> 00:45:17,119 the physics are what they are and that 1086 00:45:17,119 --> 00:45:18,960 the water surface elevation if if the 1087 00:45:18,960 --> 00:45:20,720 south arm continues to come down more 1088 00:45:20,720 --> 00:45:22,880 that would drive more flow to the north 1089 00:45:22,880 --> 00:45:24,960 um wind events this is something also 1090 00:45:24,960 --> 00:45:27,760 that is I'm really curious to look more 1091 00:45:27,760 --> 00:45:29,599 into but these episodic north wind 1092 00:45:29,599 --> 00:45:31,359 events where you can get full flow 1093 00:45:31,359 --> 00:45:33,760 reversal transport a lot of mass so it 1094 00:45:33,760 --> 00:45:36,400 can also depend on weather um because 1095 00:45:36,400 --> 00:45:38,160 during those events we just managed to 1096 00:45:38,160 --> 00:45:40,160 get these huge slugs of salt into the 1097 00:45:40,160 --> 00:45:42,240 south arm that would also help us trend 1098 00:45:42,240 --> 00:45:45,040 more into negative territory um and I 1099 00:45:45,040 --> 00:45:47,119 think just getting more measurements of 1100 00:45:47,119 --> 00:45:50,319 like is that 233 cfs representative is 1101 00:45:50,319 --> 00:45:51,920 that really kind of what we're seeing 1102 00:45:51,920 --> 00:45:53,359 and getting more paired measurements 1103 00:45:53,359 --> 00:45:54,720 will help us distinguish that because 1104 00:45:54,720 --> 00:45:56,160 there are there's quite a bit of 1105 00:45:56,160 --> 00:45:57,440 uncertainty in those first two 1106 00:45:57,440 --> 00:45:59,520 measurements made 1107 00:45:59,520 --> 00:46:02,319 >> as we continue to look at this salt flex 1108 00:46:02,319 --> 00:46:04,880 flux as long as we compare it to the 1109 00:46:04,880 --> 00:46:07,280 actual salt mass and potential changes 1110 00:46:07,280 --> 00:46:08,720 in the salt mass right 1111 00:46:08,720 --> 00:46:12,720 >> that would give us a way to confirm or 1112 00:46:12,720 --> 00:46:14,960 deny what we're calculating Yeah, and I 1113 00:46:14,960 --> 00:46:16,000 think that's what's really great about 1114 00:46:16,000 --> 00:46:17,359 our monitoring program is because we 1115 00:46:17,359 --> 00:46:19,920 have two completely independent sets of 1116 00:46:19,920 --> 00:46:22,400 data. One from the south arm of of the 1117 00:46:22,400 --> 00:46:24,000 samples that Gub collects and then one 1118 00:46:24,000 --> 00:46:25,839 at the breach. And so we can kind of 1119 00:46:25,839 --> 00:46:30,550 corroborate both of those stories. 1120 00:46:30,560 --> 00:46:32,640 » You're you're doing more monitoring now 1121 00:46:32,640 --> 00:46:34,640 than what you typically do, right? Can 1122 00:46:34,640 --> 00:46:38,960 you describe what you're doing? 1123 00:46:38,960 --> 00:46:40,400 >> Yep. We're doing roughly every other 1124 00:46:40,400 --> 00:46:43,359 week. Um, we hit it right after the BM 1125 00:46:43,359 --> 00:46:45,280 was lowered as Ryan said. Then we did a 1126 00:46:45,280 --> 00:46:46,560 week after because we were just trying 1127 00:46:46,560 --> 00:46:49,119 to capture any, you know, conditions 1128 00:46:49,119 --> 00:46:51,040 right after the change. And now we're on 1129 00:46:51,040 --> 00:46:53,680 an every two week interval. So, and 1130 00:46:53,680 --> 00:46:56,880 we'll do that until we raise the B. 1131 00:46:56,880 --> 00:46:58,480 >> Yeah. If if 1132 00:46:58,480 --> 00:47:00,240 >> you're capturing the salinity and the 1133 00:47:00,240 --> 00:47:02,640 nitrogen. 1134 00:47:02,640 --> 00:47:05,359 >> Yes. Um, we're getting nutrient samples, 1135 00:47:05,359 --> 00:47:08,160 right? Yes. I'm pretty sure we're 1136 00:47:08,160 --> 00:47:09,760 definitely we're definitely comparing 1137 00:47:09,760 --> 00:47:11,760 the water quality. 1138 00:47:11,760 --> 00:47:13,520 >> Okay, fair enough. Fair enough. We're 1139 00:47:13,520 --> 00:47:15,119 comparing the we're getting a water 1140 00:47:15,119 --> 00:47:16,480 quality sample every time they get a 1141 00:47:16,480 --> 00:47:18,560 measure for this more intensive and I'm 1142 00:47:18,560 --> 00:47:20,720 almost positive nutrients are 1143 00:47:20,720 --> 00:47:22,000 >> that's what we discussed. But we're not 1144 00:47:22,000 --> 00:47:23,040 going to see the results of the 1145 00:47:23,040 --> 00:47:23,680 nutrients. 1146 00:47:23,680 --> 00:47:26,240 >> Correct. For a much longer Yes, exactly. 1147 00:47:26,240 --> 00:47:28,400 Y 1148 00:47:28,400 --> 00:47:30,079 >> great. 1149 00:47:30,079 --> 00:47:31,599 I think that's exciting. I think that's 1150 00:47:31,599 --> 00:47:35,040 what we were hoping we would see 1151 00:47:35,040 --> 00:47:37,797 something along Zero Netflix. 1152 00:47:37,797 --> 00:47:40,870 [clears throat] 1153 00:47:40,880 --> 00:47:42,480 » Yeah. And there's many other like the 1154 00:47:42,480 --> 00:47:44,960 interface um the depth to the interface 1155 00:47:44,960 --> 00:47:48,000 is changed. It's probably a two to three 1156 00:47:48,000 --> 00:47:49,760 feet higher than it was before. So we're 1157 00:47:49,760 --> 00:47:51,280 just getting the cross-sectional area of 1158 00:47:51,280 --> 00:47:53,280 north to south flow has grown along with 1159 00:47:53,280 --> 00:47:56,000 increases in velocity. So multiple lines 1160 00:47:56,000 --> 00:47:58,319 of evidence to suggest there's more flow 1161 00:47:58,319 --> 00:48:00,800 and constituent flux coming in from the 1162 00:48:00,800 --> 00:48:03,990 north. 1163 00:48:04,000 --> 00:48:07,030 » Great. 1164 00:48:07,040 --> 00:48:09,359 » So any other questions on on what 1165 00:48:09,359 --> 00:48:13,440 they've been observing after the BM? 1166 00:48:13,440 --> 00:48:16,480 >> Sorry. Did you say the interface drop? 1167 00:48:16,480 --> 00:48:17,359 Is that 1168 00:48:17,359 --> 00:48:19,680 >> um It's higher. Sorry if I said sorry if 1169 00:48:19,680 --> 00:48:21,280 I misspoke. It's higher now. So it's 1170 00:48:21,280 --> 00:48:23,280 probably five to six feet below the 1171 00:48:23,280 --> 00:48:25,520 water surface and before it was like 8 n 1172 00:48:25,520 --> 00:48:28,400 10. So yeah, it's it's the north to 1173 00:48:28,400 --> 00:48:37,430 south cross-section is has grown. 1174 00:48:37,440 --> 00:48:40,000 » All right. Well, good. Well, now with 1175 00:48:40,000 --> 00:48:41,280 all these things that we've learned in 1176 00:48:41,280 --> 00:48:42,880 the last couple weeks, you've been 1177 00:48:42,880 --> 00:48:44,079 crunching numbers, 1178 00:48:44,079 --> 00:48:47,359 >> right? Um right. Okay. Let's see what we 1179 00:48:47,359 --> 00:48:50,160 get. All right. So taking the kind of I 1180 00:48:50,160 --> 00:48:52,079 have calculated the fall salinities 1181 00:48:52,079 --> 00:48:54,160 using a couple of different approaches. 1182 00:48:54,160 --> 00:48:56,160 One is this kind of standard water salt 1183 00:48:56,160 --> 00:48:59,440 balance model. Um and kind of the 1184 00:48:59,440 --> 00:49:02,400 results of that I only did predictions 1185 00:49:02,400 --> 00:49:04,480 for a dry warm scenario and an average 1186 00:49:04,480 --> 00:49:06,880 given the conditions that we're under. 1187 00:49:06,880 --> 00:49:09,839 Um and the resulting salinity and I'm 1188 00:49:09,839 --> 00:49:12,160 predicting through October. So roughly 1189 00:49:12,160 --> 00:49:14,800 November kind of salinity or a seasonal 1190 00:49:14,800 --> 00:49:18,079 high uh estimated using this method is 1191 00:49:18,079 --> 00:49:20,400 138 grams per liter for a dry condition, 1192 00:49:20,400 --> 00:49:23,440 dry warm condition and 133 for an 1193 00:49:23,440 --> 00:49:27,359 average. Um and not much you know not 1194 00:49:27,359 --> 00:49:29,839 much change in the salt mass really 1195 00:49:29,839 --> 00:49:31,920 given the short amount of time between 1196 00:49:31,920 --> 00:49:35,760 now and the seasonal low. 1197 00:49:35,760 --> 00:49:39,520 I kind of kept in this simplified way of 1198 00:49:39,520 --> 00:49:42,079 estimating uh fall salenities also which 1199 00:49:42,079 --> 00:49:44,559 is essentially saying from our spring 1200 00:49:44,559 --> 00:49:47,839 peak elevation to our fall low elevation 1201 00:49:47,839 --> 00:49:50,319 what is kind of a typical decline in 1202 00:49:50,319 --> 00:49:52,319 surface elevation what are the 1203 00:49:52,319 --> 00:49:55,440 associated volumes and then backing out 1204 00:49:55,440 --> 00:49:58,079 um the fall salinity based on based on 1205 00:49:58,079 --> 00:50:00,079 that and this assumes no real change in 1206 00:50:00,079 --> 00:50:03,359 salt mass but using this this approach 1207 00:50:03,359 --> 00:50:06,800 you get a range of 138 243 gram per 1208 00:50:06,800 --> 00:50:08,960 liter. So those methods, both two 1209 00:50:08,960 --> 00:50:11,200 different methods are fairly consistent, 1210 00:50:11,200 --> 00:50:13,520 around 140 grams per liter for the fall 1211 00:50:13,520 --> 00:50:15,119 low. And again, our most recent 1212 00:50:15,119 --> 00:50:17,760 measurements made Tuesday and yesterday 1213 00:50:17,760 --> 00:50:21,440 were 131 grams per liter. 1214 00:50:21,440 --> 00:50:25,760 Okay. So now for the spring, um we know, 1215 00:50:25,760 --> 00:50:27,599 you know, moving from fall to spring, 1216 00:50:27,599 --> 00:50:30,079 these these salinity predictions are 1217 00:50:30,079 --> 00:50:31,440 really controlled by the amount of 1218 00:50:31,440 --> 00:50:33,680 water. that has the largest lever on the 1219 00:50:33,680 --> 00:50:35,200 estimates we get for the spring. It's 1220 00:50:35,200 --> 00:50:36,559 the amount of water coming into the 1221 00:50:36,559 --> 00:50:38,559 system. But Jeff asked me to kind of 1222 00:50:38,559 --> 00:50:40,319 play around with a couple of scenarios 1223 00:50:40,319 --> 00:50:42,480 and I hope that this captures what 1224 00:50:42,480 --> 00:50:44,800 you're after. But um one is to raise the 1225 00:50:44,800 --> 00:50:48,240 burm on October 1, that's arbitrary. Um 1226 00:50:48,240 --> 00:50:49,680 really if you were to raise it when the 1227 00:50:49,680 --> 00:50:52,079 south arm hits 4190, that would probably 1228 00:50:52,079 --> 00:50:54,720 honestly be beginning of September based 1229 00:50:54,720 --> 00:50:56,160 on the current rate of change in the 1230 00:50:56,160 --> 00:50:58,720 south arm. But if we raise it on October 1231 00:50:58,720 --> 00:51:01,599 1st, um 1232 00:51:01,599 --> 00:51:03,440 that's one scenario. And then the second 1233 00:51:03,440 --> 00:51:05,359 scenario is to raise it not to keep it 1234 00:51:05,359 --> 00:51:06,960 open and raise it in the spring. And 1235 00:51:06,960 --> 00:51:09,040 that's just a scenario that Jeff is that 1236 00:51:09,040 --> 00:51:11,520 right 1237 00:51:11,520 --> 00:51:12,319 out a lot of things. 1238 00:51:12,319 --> 00:51:13,440 >> Okay. 1239 00:51:13,440 --> 00:51:15,680 Hopefully hopefully that captures 1240 00:51:15,680 --> 00:51:17,920 it. Um and then there's also the burm 1241 00:51:17,920 --> 00:51:20,480 height to consider. If it's a 4190, 1242 00:51:20,480 --> 00:51:21,920 there's a higher likelihood that they 1243 00:51:21,920 --> 00:51:23,760 will be over topped in the spring at a 1244 00:51:23,760 --> 00:51:26,000 certain point. So I estimated that based 1245 00:51:26,000 --> 00:51:28,000 on previous rates of change to be around 1246 00:51:28,000 --> 00:51:30,480 February 1st is when we might see overt 1247 00:51:30,480 --> 00:51:32,319 topping from south to north and then 1248 00:51:32,319 --> 00:51:34,640 again start to lose solar mass. So these 1249 00:51:34,640 --> 00:51:37,200 are the kinds of um factors that I was 1250 00:51:37,200 --> 00:51:38,960 working with. So and I'm going to 1251 00:51:38,960 --> 00:51:41,680 display this all using our um iso mass 1252 00:51:41,680 --> 00:51:43,520 plots which integrate elevation the 1253 00:51:43,520 --> 00:51:45,920 salinity and the mass. So starting with 1254 00:51:45,920 --> 00:51:47,680 our most recent measurements on August 1255 00:51:47,680 --> 00:51:51,280 4th again 131 grams per liter sitting at 1256 00:51:51,280 --> 00:51:54,400 4190.6 six feet in the south arm and an 1257 00:51:54,400 --> 00:51:57,920 estimate of 864 million tons of salt. 1258 00:51:57,920 --> 00:52:00,559 Moving forward to then um the fall 1259 00:52:00,559 --> 00:52:01,920 prediction and kind of just walking 1260 00:52:01,920 --> 00:52:04,000 through this is a slightly different 1261 00:52:04,000 --> 00:52:05,520 approach that I took on the previous 1262 00:52:05,520 --> 00:52:08,319 two, but the this results on 147 grams 1263 00:52:08,319 --> 00:52:10,400 per liter and that's assuming that's 1264 00:52:10,400 --> 00:52:12,000 trying to account for the amount of salt 1265 00:52:12,000 --> 00:52:14,800 mass we gain due to the um the breach 1266 00:52:14,800 --> 00:52:18,160 being open. And that's based on previous 1267 00:52:18,160 --> 00:52:20,960 conditions. Uh almost 20 million tons 1268 00:52:20,960 --> 00:52:22,800 between now and October is the amount of 1269 00:52:22,800 --> 00:52:25,599 salt mass um that I'm estimating might 1270 00:52:25,599 --> 00:52:28,079 be added. 1271 00:52:28,079 --> 00:52:30,400 And then kind of moving forward into 1272 00:52:30,400 --> 00:52:32,800 May, again, this is largely controlled 1273 00:52:32,800 --> 00:52:35,599 by the amount of water being added 1274 00:52:35,599 --> 00:52:38,160 between the fall and the spring. So the 1275 00:52:38,160 --> 00:52:40,640 different water conditions that I um 1276 00:52:40,640 --> 00:52:44,079 consider are basically a repeat of 2026 1277 00:52:44,079 --> 00:52:46,880 runoff. So that would put us at 4190.6. 1278 00:52:46,880 --> 00:52:49,280 That's the lowest kind of horizontal 1279 00:52:49,280 --> 00:52:51,440 dashed line you see here. For a mean 1280 00:52:51,440 --> 00:52:53,839 runoff condition, that's about 2.2 feet 1281 00:52:53,839 --> 00:52:56,559 of gain. That's 4191.5 1282 00:52:56,559 --> 00:52:58,960 here. this middle line and then kind of 1283 00:52:58,960 --> 00:53:01,839 an extreme uh end of the spectrum if we 1284 00:53:01,839 --> 00:53:04,240 repeat 2023 runoff which is that high 1285 00:53:04,240 --> 00:53:07,119 end and um and then we have these kind 1286 00:53:07,119 --> 00:53:09,839 of different salt mass configurations if 1287 00:53:09,839 --> 00:53:12,800 we over top the burm on February 1 if we 1288 00:53:12,800 --> 00:53:14,880 assume no over topping because in some 1289 00:53:14,880 --> 00:53:17,359 of these instances if it's at 4192 you 1290 00:53:17,359 --> 00:53:20,400 would not over top and then um and then 1291 00:53:20,400 --> 00:53:22,480 kind of just assuming a median rate of 1292 00:53:22,480 --> 00:53:24,079 net flux the scenario two is where we 1293 00:53:24,079 --> 00:53:26,000 keep it open and so actually in this 1294 00:53:26,000 --> 00:53:26,880 scenario 1295 00:53:26,880 --> 00:53:28,559 And I'll show plots of this, but in this 1296 00:53:28,559 --> 00:53:30,000 scenario, if you keep it open, you 1297 00:53:30,000 --> 00:53:32,720 actually end up losing losing salt, a 1298 00:53:32,720 --> 00:53:37,040 net loss because of how um because when 1299 00:53:37,040 --> 00:53:38,640 you get a pulse of water into the south 1300 00:53:38,640 --> 00:53:40,640 arm, you end up having kind of a net 1301 00:53:40,640 --> 00:53:42,400 loss of salt to the north and during 1302 00:53:42,400 --> 00:53:45,760 these seasons of winter and uh spring. 1303 00:53:45,760 --> 00:53:48,400 So the results of this is really in you 1304 00:53:48,400 --> 00:53:50,480 know what the take-home for all of you 1305 00:53:50,480 --> 00:53:52,240 are in these summarized in these boxes. 1306 00:53:52,240 --> 00:53:55,359 So for a dry warm condition estimate of 1307 00:53:55,359 --> 00:53:58,240 130ish gram per liter in the spring it 1308 00:53:58,240 --> 00:54:00,000 really these different scenarios of this 1309 00:54:00,000 --> 00:54:01,760 salt mass exchange don't change it a 1310 00:54:01,760 --> 00:54:03,520 whole lot maybe by 2 to three gram per 1311 00:54:03,520 --> 00:54:04,960 liter according to these calculations 1312 00:54:04,960 --> 00:54:06,872 it's really driven by the water. 1313 00:54:06,872 --> 00:54:08,480 [snorts] So average conditions you're 1314 00:54:08,480 --> 00:54:11,520 sitting more at about 122 to 125 grams 1315 00:54:11,520 --> 00:54:13,520 per liter and then for a very wet 1316 00:54:13,520 --> 00:54:17,119 condition 122 to 105 g. That gives you 1317 00:54:17,119 --> 00:54:20,480 some idea of um what spring could be 1318 00:54:20,480 --> 00:54:23,200 like. 1319 00:54:23,200 --> 00:54:26,559 But I wanted to um to just make it clear 1320 00:54:26,559 --> 00:54:29,440 that I I based these estimates of the 1321 00:54:29,440 --> 00:54:31,040 flux and the amount of mass change in 1322 00:54:31,040 --> 00:54:34,079 the south arm on a median condition. So 1323 00:54:34,079 --> 00:54:37,040 on a distribution of when the breach was 1324 00:54:37,040 --> 00:54:38,800 at for the breach condition was similar 1325 00:54:38,800 --> 00:54:40,319 to what it is now. So when the burm was 1326 00:54:40,319 --> 00:54:43,440 at 4183. This is the period from 2018 to 1327 00:54:43,440 --> 00:54:46,319 2022. And then for each month I 1328 00:54:46,319 --> 00:54:48,960 basically just calculated the daily the 1329 00:54:48,960 --> 00:54:51,920 net daily flux. So for the box plots 1330 00:54:51,920 --> 00:54:54,160 that are above zero that's a net salts 1331 00:54:54,160 --> 00:54:56,720 export from the south arm. So basically 1332 00:54:56,720 --> 00:55:01,359 net loss of salt and then for um for 1333 00:55:01,359 --> 00:55:03,440 values below zero that's a net import. 1334 00:55:03,440 --> 00:55:04,800 And just so you can see kind of the 1335 00:55:04,800 --> 00:55:07,200 seasonality of this 1336 00:55:07,200 --> 00:55:08,800 and that this is really driven by 1337 00:55:08,800 --> 00:55:12,079 conditions in like 2019 and 2020. 1338 00:55:12,079 --> 00:55:14,000 Based on kind of all this data clumped 1339 00:55:14,000 --> 00:55:16,079 together, you really kind of get an 1340 00:55:16,079 --> 00:55:18,000 import of salt during these months from 1341 00:55:18,000 --> 00:55:20,640 May to October. That's when you start to 1342 00:55:20,640 --> 00:55:22,800 get um the large surface elevations 1343 00:55:22,800 --> 00:55:24,720 getting closer together and you get a 1344 00:55:24,720 --> 00:55:27,200 net import of salt during that those 1345 00:55:27,200 --> 00:55:30,240 seasons. So, keeping it open longer may 1346 00:55:30,240 --> 00:55:33,200 not be beneficial um because you have a 1347 00:55:33,200 --> 00:55:35,119 net export of salt anyway, at least for 1348 00:55:35,119 --> 00:55:37,359 the purposes of wanting to get salt to 1349 00:55:37,359 --> 00:55:40,400 the um south arm. 1350 00:55:40,400 --> 00:55:45,040 But it varies and um so for 2021 this is 1351 00:55:45,040 --> 00:55:49,359 so same similar plot monthly for 2021 um 1352 00:55:49,359 --> 00:55:51,520 based on the conditions of that year we 1353 00:55:51,520 --> 00:55:54,400 actually estimate a net import during 1354 00:55:54,400 --> 00:55:57,280 most of that year. Contrast that with 1355 00:55:57,280 --> 00:56:00,000 2022 lake elevations were really low 1356 00:56:00,000 --> 00:56:01,680 salinities were really high in the south 1357 00:56:01,680 --> 00:56:04,960 arm and we actually had um much more 1358 00:56:04,960 --> 00:56:07,599 frequent salt export. So this is what 1359 00:56:07,599 --> 00:56:09,200 I've been racking my brain for the last 1360 00:56:09,200 --> 00:56:11,200 few days of like what are the conditions 1361 00:56:11,200 --> 00:56:13,119 now most represent what do they match 1362 00:56:13,119 --> 00:56:16,400 most closely 2021 2022 1363 00:56:16,400 --> 00:56:18,240 um we have water [clears throat] surface 1364 00:56:18,240 --> 00:56:21,839 elevations similar to 20 2022 but the 1365 00:56:21,839 --> 00:56:23,760 density differential is much different 1366 00:56:23,760 --> 00:56:26,319 in 2022 we had really high salinities in 1367 00:56:26,319 --> 00:56:29,119 the south arm um and so that difference 1368 00:56:29,119 --> 00:56:31,200 between the south and the north was less 1369 00:56:31,200 --> 00:56:33,599 now we have much fresher conditions so 1370 00:56:33,599 --> 00:56:35,520 the physics should dictate that we get 1371 00:56:35,520 --> 00:56:36,960 much more flow 1372 00:56:36,960 --> 00:56:38,640 um from the north coming in because of 1373 00:56:38,640 --> 00:56:42,559 that that density different. So um just 1374 00:56:42,559 --> 00:56:44,480 something to keep in mind as we try to 1375 00:56:44,480 --> 00:56:46,720 anticipate what the flux is going to be 1376 00:56:46,720 --> 00:56:48,960 now uh is that it can be quite 1377 00:56:48,960 --> 00:56:50,640 complicated. And another factor of 1378 00:56:50,640 --> 00:56:54,799 course is like wind. What if 2021 was a 1379 00:56:54,799 --> 00:56:57,200 particularly windy year with a lot of 1380 00:56:57,200 --> 00:56:59,599 wind out of the north that would drive 1381 00:56:59,599 --> 00:57:02,480 um a lot of salt into the south. So, 1382 00:57:02,480 --> 00:57:04,319 those are kind of a few other factors we 1383 00:57:04,319 --> 00:57:06,960 need to be considering as we try to like 1384 00:57:06,960 --> 00:57:08,640 think about what this year is going to 1385 00:57:08,640 --> 00:57:10,480 bring. Or at least that's what I've been 1386 00:57:10,480 --> 00:57:13,040 thinking about. Um, 1387 00:57:13,040 --> 00:57:15,200 this is just a time series of that same 1388 00:57:15,200 --> 00:57:18,799 data net salt flux from 2019 to 2022. 1389 00:57:18,799 --> 00:57:23,440 You can really see how um in these years 1390 00:57:23,440 --> 00:57:26,000 we had, you know, kind of this nice 1391 00:57:26,000 --> 00:57:29,440 seasonality 2022 or sorry, sorry, 2021 1392 00:57:29,440 --> 00:57:32,000 dominated by net flux to the north and 1393 00:57:32,000 --> 00:57:34,160 then in 2022 it really begins to break 1394 00:57:34,160 --> 00:57:35,760 down even though the water surface 1395 00:57:35,760 --> 00:57:39,280 elevations were similar. Um, so yeah, 1396 00:57:39,280 --> 00:57:42,160 maybe this is too much information as I 1397 00:57:42,160 --> 00:57:45,599 try to problem solve it myself, but um 1398 00:57:45,599 --> 00:57:47,119 these are just yeah and then water 1399 00:57:47,119 --> 00:57:48,880 surface elevation I just overlaid in 1400 00:57:48,880 --> 00:57:50,799 this black dotted line. So really 1401 00:57:50,799 --> 00:57:52,720 matches closely when we get these big 1402 00:57:52,720 --> 00:57:54,799 swings in water surface elevation you 1403 00:57:54,799 --> 00:57:56,559 see that salt flux sort of following 1404 00:57:56,559 --> 00:57:58,960 that pattern and then these two years 1405 00:57:58,960 --> 00:58:01,200 are just responding very differently to 1406 00:58:01,200 --> 00:58:04,400 that very same um variable which is the 1407 00:58:04,400 --> 00:58:06,000 water surface elevation difference. I 1408 00:58:06,000 --> 00:58:08,559 think this is mostly driven by increase 1409 00:58:08,559 --> 00:58:11,359 in density in the cell farm, but we got 1410 00:58:11,359 --> 00:58:13,280 to look at the wind too and just see 1411 00:58:13,280 --> 00:58:16,160 what the effect of that is too. And I 1412 00:58:16,160 --> 00:58:18,240 will say these are based on um daily 1413 00:58:18,240 --> 00:58:21,200 discharge estimates by S made by S and 1414 00:58:21,200 --> 00:58:23,635 Eric, his previous grad student. 1415 00:58:23,635 --> 00:58:25,599 [clears throat] 1416 00:58:25,599 --> 00:58:27,520 Um and with that, I'll just I'm happy to 1417 00:58:27,520 --> 00:58:30,240 take questions. I just kind of wanted to 1418 00:58:30,240 --> 00:58:33,680 run folks through um you know as we try 1419 00:58:33,680 --> 00:58:37,839 to predict what salt flux might be it's pretty complicated and there's a 1420 00:58:37,839 --> 00:58:40,880 number of factors to consider but that 1421 00:58:40,880 --> 00:58:43,040 the spring predictions again are really 1422 00:58:43,040 --> 00:58:47,920 driven by water so yeah 1423 00:58:47,920 --> 00:58:51,589 >> excellent yeah 1424 00:58:51,599 --> 00:58:53,765 » doesn't sound like it got simpler 1425 00:58:53,765 --> 00:58:54,240 [laughter] 1426 00:58:54,240 --> 00:58:57,599 >> I know I was hoping you would 1427 00:58:57,599 --> 00:58:58,400 but yeah 1428 00:58:58,400 --> 00:59:00,240 >> I I think you identified a lot of key 1429 00:59:00,240 --> 00:59:00,880 factors. 1430 00:59:00,880 --> 00:59:02,319 >> I guess they have a well 1431 00:59:02,319 --> 00:59:04,240 >> key variables that help 1432 00:59:04,240 --> 00:59:05,280 >> drive it. 1433 00:59:05,280 --> 00:59:07,440 >> Yeah. And I did have a call with some 1434 00:59:07,440 --> 00:59:08,799 this morning to just try and make sense 1435 00:59:08,799 --> 00:59:10,640 of all this stuff and it was he had a 1436 00:59:10,640 --> 00:59:12,799 lot of great insights. And so if you 1437 00:59:12,799 --> 00:59:15,680 want us to try and get to more precise 1438 00:59:15,680 --> 00:59:17,760 predictions about the salt flux, I think 1439 00:59:17,760 --> 00:59:20,480 he would have some really good insight 1440 00:59:20,480 --> 00:59:23,680 in how to do that um just given his 1441 00:59:23,680 --> 00:59:26,000 expertise of the physics of reach. So, 1442 00:59:26,000 --> 00:59:27,920 we can we can keep working on that if 1443 00:59:27,920 --> 00:59:29,680 that's of use. And I think I would yeah 1444 00:59:29,680 --> 00:59:31,839 try to bring some into trying to figure 1445 00:59:31,839 --> 00:59:34,720 out some of those methods and things. 1446 00:59:34,720 --> 00:59:35,599 >> Yeah. 1447 00:59:35,599 --> 00:59:37,680 >> Christine, can you bring that slide back 1448 00:59:37,680 --> 00:59:39,920 up? 1449 00:59:39,920 --> 00:59:41,200 >> I don't have a question.

The density was different. 1471 01:00:25,760 --> 01:00:30,069 >> Yeah, maybe it's closer to 2021. 1472 01:00:30,079 --> 01:00:31,359 » In the previous meeting, I thought you 1473 01:00:31,359 --> 01:00:33,920 had like an October 27. 1474 01:00:33,920 --> 01:00:37,920 >> We did that. 1475 01:00:37,920 --> 01:00:39,200 >> Well, it seems like there's maybe too 1476 01:00:39,200 --> 01:00:42,000 many variables, right? when we raise a 1477 01:00:42,000 --> 01:00:43,920 whether it's now then what kind of 1478 01:00:43,920 --> 01:00:48,549 weather 1479 01:00:48,559 --> 01:00:51,599 » I mean just one general comment is 1480 01:00:51,599 --> 01:00:53,359 regardless of what happens according to 1481 01:00:53,359 --> 01:00:56,640 your predictions we're in a good spot 1482 01:00:56,640 --> 01:00:58,319 that's just a general comment I would 1483 01:00:58,319 --> 01:01:00,960 make but the other one is um when we 1484 01:01:00,960 --> 01:01:03,599 look at salt mass it's it's a tool for 1485 01:01:03,599 --> 01:01:06,079 us to verify if you know what we thought 1486 01:01:06,079 --> 01:01:07,440 was going to happen is actually 1487 01:01:07,440 --> 01:01:10,480 happening but in order to try anticipate 1488 01:01:10,480 --> 01:01:12,400 what's going to happen at least towards 1489 01:01:12,400 --> 01:01:15,520 the future and refine that ability. I do 1490 01:01:15,520 --> 01:01:17,680 agree with you. Um I think at least 1491 01:01:17,680 --> 01:01:19,680 that's what you're uh you were saying is 1492 01:01:19,680 --> 01:01:22,880 that we could benefit from Psalms's 1493 01:01:22,880 --> 01:01:25,839 expertise and continue 1494 01:01:25,839 --> 01:01:28,960 to model that. I would certainly highly 1495 01:01:28,960 --> 01:01:31,440 recommend that if funds are available to 1496 01:01:31,440 --> 01:01:35,910 do that. 1497 01:01:35,920 --> 01:01:38,480 » Yeah. Yeah. especially his computational 1498 01:01:38,480 --> 01:01:40,960 fluid dynamics model which is based on 1499 01:01:40,960 --> 01:01:43,280 physics and I think he would be able to 1500 01:01:43,280 --> 01:01:46,000 um give much more insight into flow 1501 01:01:46,000 --> 01:01:48,480 dynamics. We did also did you mention 1502 01:01:48,480 --> 01:01:50,000 this? We surveyed the bethimemetry 1503 01:01:50,000 --> 01:01:52,400 yesterday also of the kind of the breach 1504 01:01:52,400 --> 01:01:54,960 opening. Um, and so that would also help 1505 01:01:54,960 --> 01:01:57,119 feed it into a model for someone like 1506 01:01:57,119 --> 01:01:59,040 SAM or water resources to say, well, 1507 01:01:59,040 --> 01:02:01,520 okay, how is this 4183 condition 1508 01:02:01,520 --> 01:02:04,000 different than 2021 2022 because it it 1509 01:02:04,000 --> 01:02:06,559 might be slightly different and um Craig 1510 01:02:06,559 --> 01:02:08,559 was just mentioning how there could be 1511 01:02:08,559 --> 01:02:10,400 other factors that are controlling the 1512 01:02:10,400 --> 01:02:12,480 flow that we may not be aware of 1513 01:02:12,480 --> 01:02:14,720 >> because right now there's beimemetry, 1514 01:02:14,720 --> 01:02:18,799 there's um density um and then there's 1515 01:02:18,799 --> 01:02:21,599 lake elevation and the head difference. 1516 01:02:21,599 --> 01:02:23,280 I mean that's 1517 01:02:23,280 --> 01:02:25,440 factors that are playing into this 1518 01:02:25,440 --> 01:02:36,789 >> and there might be other exampations 1519 01:02:36,799 --> 01:02:39,040 you talked about how if I remember right 1520 01:02:39,040 --> 01:02:41,760 when there is no burn we expect to see a 1521 01:02:41,760 --> 01:02:43,599 deep layer 1522 01:02:43,599 --> 01:02:47,520 >> do do we know what time frame that would 1523 01:02:47,520 --> 01:02:49,760 expect to happen if we keep this open 1524 01:02:49,760 --> 01:02:52,480 how that affect 1525 01:02:52,480 --> 01:02:54,480 What did we measure the last time? Like 1526 01:02:54,480 --> 01:02:55,920 six six months. 1527 01:02:55,920 --> 01:02:59,200 >> Yeah, there was like a sixmon lag. Yeah, 1528 01:02:59,200 --> 01:03:02,799 this is based on the what were the years 1529 01:03:02,799 --> 01:03:03,680 for that study? 1530 01:03:03,680 --> 01:03:05,440 >> 2016 1531 01:03:05,440 --> 01:03:08,720 well no 2015 to 2017 1532 01:03:08,720 --> 01:03:10,480 >> and that's published by one of Bill 1533 01:03:10,480 --> 01:03:12,319 Johnson's graduate students in a 1534 01:03:12,319 --> 01:03:13,920 journal. So we would point you to it but 1535 01:03:13,920 --> 01:03:17,119 it seems like that was a 1536 01:03:17,119 --> 01:03:17,920 last time 1537 01:03:17,920 --> 01:03:19,839 >> and we haven't observed it yet. There 1538 01:03:19,839 --> 01:03:22,079 are Mr. Buys up there that might be able 1539 01:03:22,079 --> 01:03:24,000 to catch a thermocline. If we can get a 1540 01:03:24,000 --> 01:03:25,200 water quality measurement associated 1541 01:03:25,200 --> 01:03:26,720 with that, we be able to see when it 1542 01:03:26,720 --> 01:03:30,559 develops. Um, another factor to consider 1543 01:03:30,559 --> 01:03:32,480 is how shallow the cell farm is. Right 1544 01:03:32,480 --> 01:03:34,240 now, you get a lot of wind action that 1545 01:03:34,240 --> 01:03:37,119 can actually mix that out. So, we'll see 1546 01:03:37,119 --> 01:03:37,760 what we see. 1547 01:03:37,760 --> 01:03:40,319 >> If we do see that, do we expect a change 1548 01:03:40,319 --> 01:03:46,160 in the way that the BM actually flows? 1549 01:03:46,160 --> 01:03:48,480 Expect a difference in the transfer from 1550 01:03:48,480 --> 01:03:51,750 north to south, right? 1551 01:03:51,760 --> 01:03:53,760 um with the deep grind layer. 1552 01:03:53,760 --> 01:03:54,880 >> Yeah, 1553 01:03:54,880 --> 01:03:56,720 >> not to my knowledge. 1554 01:03:56,720 --> 01:03:58,880 >> I think that 1555 01:03:58,880 --> 01:04:01,680 that's putting up that schematic 1556 01:04:01,680 --> 01:04:09,910 use. 1557 01:04:09,920 --> 01:04:14,064 » Yeah, maybe not not so useful, but we we have we we have kind of a deep 1558 01:04:14,064 --> 01:04:15,200 [clears throat] pool where our uplooker 1559 01:04:15,200 --> 01:04:20,799 is right right now. Um I don't know. 1560 01:04:20,799 --> 01:04:22,319 Let's let's just do the monitoring and 1561 01:04:22,319 --> 01:04:25,520 see how it holds out. Yeah. 1562 01:04:25,520 --> 01:04:26,400 >> Curiosity. 1563 01:04:26,400 --> 01:04:30,950 >> Yeah. 1564 01:04:30,960 --> 01:04:32,880 So I think one of the I think one of the 1565 01:04:32,880 --> 01:04:35,039 hopes or things that we had talked about 1566 01:04:35,039 --> 01:04:36,720 was 1567 01:04:36,720 --> 01:04:39,599 that we saw this decline in nitrogen 1568 01:04:39,599 --> 01:04:43,039 flux to the south arm that if we were 1569 01:04:43,039 --> 01:04:45,119 able to lower the burm and open that 1570 01:04:45,119 --> 01:04:47,839 breach up, we could get reestablish the 1571 01:04:47,839 --> 01:04:50,640 birectional flow hopefully get to a net 1572 01:04:50,640 --> 01:04:56,000 zero salt flux. But um the big question 1573 01:04:56,000 --> 01:04:59,440 is going to be just the nitrogen flux. 1574 01:04:59,440 --> 01:05:01,200 We're getting more nitrogen now coming 1575 01:05:01,200 --> 01:05:04,960 from the north arm, but are we exporting 1576 01:05:04,960 --> 01:05:06,799 nitrogen? 1577 01:05:06,799 --> 01:05:10,400 Does that offset the birectional flow? 1578 01:05:10,400 --> 01:05:10,799 >> Yep. 1579 01:05:10,799 --> 01:05:13,680 >> We don't know. 1580 01:05:13,680 --> 01:05:15,440 >> I guess historically when we had 1581 01:05:15,440 --> 01:05:18,799 birectional flow, the nitrogen 1582 01:05:18,799 --> 01:05:25,430 was okay, right? So, so maybe 1583 01:05:25,440 --> 01:05:26,960 » it was maintained at certain levels. 1584 01:05:26,960 --> 01:05:29,280 Yeah. And it as we know the breach is 1585 01:05:29,280 --> 01:05:31,119 the largest source of nitrogen and 1586 01:05:31,119 --> 01:05:36,549 phosphorus to the south farm. So, 1587 01:05:36,559 --> 01:05:38,799 » fantastic. Any other questions or 1588 01:05:38,799 --> 01:05:42,319 comments on that? Thank you. 1589 01:05:42,319 --> 01:05:45,680 >> Takes a lot of wizardry. 1590 01:05:45,680 --> 01:05:48,400 >> Yeah. And if there I if there are more 1591 01:05:48,400 --> 01:05:50,319 um if there are specific questions or 1592 01:05:50,319 --> 01:05:52,400 specific scenarios I think we could we 1593 01:05:52,400 --> 01:05:54,240 could tackle it you know just need a 1594 01:05:54,240 --> 01:05:56,960 little more just probably some time um 1595 01:05:56,960 --> 01:05:59,280 to chew on things but if if any of this 1596 01:05:59,280 --> 01:06:01,200 if you like any of it in more depth I 1597 01:06:01,200 --> 01:06:02,799 think it's possible and we can learn a 1598 01:06:02,799 --> 01:06:05,829 lot. 1599 01:06:05,839 --> 01:06:07,520 » Great. 1600 01:06:07,520 --> 01:06:10,880 Thank you. Um Craig I don't want to mean 1601 01:06:10,880 --> 01:06:12,799 to put you on the spot but I know you 1602 01:06:12,799 --> 01:06:16,079 you've been working with Psalm and state 1603 01:06:16,079 --> 01:06:19,119 on just the hydraulic modeling. Do you 1604 01:06:19,119 --> 01:06:21,520 want to speak to that or do you want to 1605 01:06:21,520 --> 01:06:23,119 we can do it next time too? 1606 01:06:23,119 --> 01:06:26,799 >> We're we're still developing things. 1607 01:06:26,799 --> 01:06:30,559 It's getting closer. I I I'm hoping that 1608 01:06:30,559 --> 01:06:33,599 the time will come when regardless of 1609 01:06:33,599 --> 01:06:35,920 the salinity difference, regardless of 1610 01:06:35,920 --> 01:06:39,520 the elevation of of the burm, we'll have 1611 01:06:39,520 --> 01:06:43,200 a more reliable way of quickly 1612 01:06:43,200 --> 01:06:45,200 estimating the flows through the the 1613 01:06:45,200 --> 01:06:48,720 bridge, but I I don't have anything for 1614 01:06:48,720 --> 01:06:51,359 you right now. Okay. We're looking 1615 01:06:51,359 --> 01:06:54,480 forward to it. USGS is is telling us 1616 01:06:54,480 --> 01:06:56,319 that soon they'll have additional data 1617 01:06:56,319 --> 01:06:58,640 for us and they told us that a couple of 1618 01:06:58,640 --> 01:07:01,839 months ago and uh we're we're still 1619 01:07:01,839 --> 01:07:03,280 looking forward to some additional data 1620 01:07:03,280 --> 01:07:04,240 to help us with that. 1621 01:07:04,240 --> 01:07:07,440 >> Yeah, once once again uh we're kind of 1622 01:07:07,440 --> 01:07:09,680 holding the show up a little bit. Um 1623 01:07:09,680 --> 01:07:12,480 this has this gets to the uncertainty um 1624 01:07:12,480 --> 01:07:14,480 in in the build measurements 1625 01:07:14,480 --> 01:07:16,960 particularly the the north to south. Um 1626 01:07:16,960 --> 01:07:19,280 but also we've been doing a lot of work 1627 01:07:19,280 --> 01:07:22,160 um Andy and Mike Freeman on developing 1628 01:07:22,160 --> 01:07:24,480 an index velocity rating for both flow 1629 01:07:24,480 --> 01:07:26,240 directions. And so that's just that's a 1630 01:07:26,240 --> 01:07:29,599 standard you know way USGS 1631 01:07:29,599 --> 01:07:36,240 uh will develop um discharge ratings for for gauges that are unusual or you 1632 01:07:36,240 --> 01:07:37,520 can't get by with a simple stage 1633 01:07:37,520 --> 01:07:39,760 discharge rating. So these guys have 1634 01:07:39,760 --> 01:07:44,799 been working really hard on this and um 1635 01:07:44,799 --> 01:07:48,559 we're getting close. Um but the the um 1636 01:07:48,559 --> 01:07:51,039 the field measurements of discharge uh 1637 01:07:51,039 --> 01:07:52,640 the uncertainty there that that's 1638 01:07:52,640 --> 01:07:55,440 something we want to um 1639 01:07:55,440 --> 01:07:56,880 make sure we completely understand 1640 01:07:56,880 --> 01:07:59,599 before we lay out our progress on index 1641 01:07:59,599 --> 01:08:03,119 velocity uh ratings because everything's 1642 01:08:03,119 --> 01:08:05,119 sort of based on the field measurements 1643 01:08:05,119 --> 01:08:08,000 of discharge. So, SAS is about ready to 1644 01:08:08,000 --> 01:08:11,440 finish up her work on this uh another 1645 01:08:11,440 --> 01:08:15,280 week or so and uh 1646 01:08:15,280 --> 01:08:17,279 and her dissertation won't be done for 1647 01:08:17,279 --> 01:08:20,400 another two years. So, we'll we'll have 1648 01:08:20,400 --> 01:08:22,560 I suspect we'll have her back again next 1649 01:08:22,560 --> 01:08:25,040 summer and kind of complete this with 1650 01:08:25,040 --> 01:08:27,839 the uh wonderful data that you will be 1651 01:08:27,839 --> 01:08:30,719 providing us and we look forward to 1652 01:08:30,719 --> 01:08:32,239 that. 1653 01:08:32,239 --> 01:08:33,920 >> Fantastic. 1654 01:08:33,920 --> 01:08:34,319 >> All right, 1655 01:08:34,319 --> 01:08:38,480 >> that's about it. Okay. Well, thank you. 1656 01:08:38,480 --> 01:08:43,440 So, I I think that was I mean I have one 1657 01:08:43,440 --> 01:08:45,520 more thing on the agenda was just to 1658 01:08:45,520 --> 01:08:47,040 discuss the salinity management 1659 01:08:47,040 --> 01:08:49,120 framework or the [snorts] guide on the 1660 01:08:49,120 --> 01:08:53,839 plan and that's been I don't know what 1661 01:08:53,839 --> 01:08:56,960 direction if you know I don't know that 1662 01:08:56,960 --> 01:09:02,880 anybody's reading that again and again. Um but that's still on the 1663 01:09:02,880 --> 01:09:06,400 agenda. um in terms of things that we're 1664 01:09:06,400 --> 01:09:10,000 working on as a committee um and I think 1665 01:09:10,000 --> 01:09:13,679 the la the last change was made um in 1666 01:09:13,679 --> 01:09:15,679 April and mostly was just to make sure 1667 01:09:15,679 --> 01:09:17,759 that it was flexible for such issues 1668 01:09:17,759 --> 01:09:19,679 like nitrogen 1669 01:09:19,679 --> 01:09:23,839 um you know that that that it wasn't too 1670 01:09:23,839 --> 01:09:25,920 prescriptive that we would be able to 1671 01:09:25,920 --> 01:09:29,759 adapt for things like that that come up 1672 01:09:29,759 --> 01:09:33,040 um but I think what we want to try to do 1673 01:09:33,040 --> 01:09:35,279 is um we want to be able to reference it 1674 01:09:35,279 --> 01:09:39,759 in the CMP and and as a as a I guess 1675 01:09:39,759 --> 01:09:44,400 another document that that the CMP is um 1676 01:09:44,400 --> 01:09:47,359 can rely upon. So we'd love to get it 1677 01:09:47,359 --> 01:09:50,239 finalized and is that Ben do you think 1678 01:09:50,239 --> 01:09:52,560 that's something we can move forward 1679 01:09:52,560 --> 01:09:54,719 with? You want to move forward? 1680 01:09:54,719 --> 01:09:56,239 I mean, I'm comfortable with it, but I 1681 01:09:56,239 --> 01:09:58,719 think uh you know, I think ideally we 1682 01:09:58,719 --> 01:10:00,239 probably need to nudge people before the 1683 01:10:00,239 --> 01:10:02,239 meeting, give them a reminder that we're 1684 01:10:02,239 --> 01:10:05,360 going to, you know, tell that 1685 01:10:05,360 --> 01:10:06,880 just knowing how busy everybody is. I 1686 01:10:06,880 --> 01:10:08,159 would imagine not a lot of people were 1687 01:10:08,159 --> 01:10:09,840 looking at it right before this meeting. 1688 01:10:09,840 --> 01:10:12,800 So maybe it's something that we, you 1689 01:10:12,800 --> 01:10:14,560 know, unless someone feels strongly 1690 01:10:14,560 --> 01:10:16,080 maybe we table this till the next 1691 01:10:16,080 --> 01:10:18,239 meeting and then a week or so before the 1692 01:10:18,239 --> 01:10:19,760 meeting we remind people that they need 1693 01:10:19,760 --> 01:10:23,040 to pop in and provide any final comments 1694 01:10:23,040 --> 01:10:25,199 or concerns 1695 01:10:25,199 --> 01:10:30,560 unless anybody uh is ready to roll. 1696 01:10:30,560 --> 01:10:32,000 Sounds like we should just wait. 1697 01:10:32,000 --> 01:10:33,360 >> Yep, let's do that. 1698 01:10:33,360 --> 01:10:34,880 >> Okay, 1699 01:10:34,880 --> 01:10:37,679 great. Well, I I think then all that's 1700 01:10:37,679 --> 01:10:40,960 left is to schedule our next meeting. Um 1701 01:10:40,960 --> 01:10:43,679 I think the you know, if we go by our 1702 01:10:43,679 --> 01:10:46,480 typical pattern, it would be Thursday, 1703 01:10:46,480 --> 01:10:49,360 October 22nd. 1704 01:10:49,360 --> 01:10:52,080 Um unless you want to meet before then. 1705 01:10:52,080 --> 01:10:53,679 >> I suggest we meet before them just 1706 01:10:53,679 --> 01:10:55,600 because it's I think there's a crucial 1707 01:10:55,600 --> 01:10:58,159 time period in October that we need to 1708 01:10:58,159 --> 01:11:01,199 decide if we're going to you know raise 1709 01:11:01,199 --> 01:11:03,840 the BM. That would be probably at least 1710 01:11:03,840 --> 01:11:05,600 one of the decision points is whether we 1711 01:11:05,600 --> 01:11:07,679 do it at the end of October as Christine 1712 01:11:07,679 --> 01:11:10,400 kind of model or if we're waiting and I 1713 01:11:10,400 --> 01:11:11,440 think we're going to need a little bit 1714 01:11:11,440 --> 01:11:14,159 of be time to figure out if we're going 1715 01:11:14,159 --> 01:11:15,760 to get a freebie again or we're going to 1716 01:11:15,760 --> 01:11:17,920 have to contract it or how that'll pan 1717 01:11:17,920 --> 01:11:20,239 out. 1718 01:11:20,239 --> 01:11:24,320 So um so September probably in a month 1719 01:11:24,320 --> 01:11:24,880 from now 1720 01:11:24,880 --> 01:11:26,560 >> maybe 1721 01:11:26,560 --> 01:11:29,360 is there like any um sampling dates that 1722 01:11:29,360 --> 01:11:31,760 correspond where we could you know get 1723 01:11:31,760 --> 01:11:35,520 the most fresh recent data that we could 1724 01:11:35,520 --> 01:11:37,920 say you know let's meet this many days 1725 01:11:37,920 --> 01:11:39,679 after that gives you a chance to do your 1726 01:11:39,679 --> 01:11:41,040 modeling so we're not like 1727 01:11:41,040 --> 01:11:42,080 >> for the south 1728 01:11:42,080 --> 01:11:43,280 >> yeah I mean like this time we're looking 1729 01:11:43,280 --> 01:11:45,440 at June 22nd is there a time frame so we 1730 01:11:45,440 --> 01:11:46,880 could be like a little further along and 1731 01:11:46,880 --> 01:11:48,239 get a little more 1732 01:11:48,239 --> 01:11:50,880 >> recent I know Gle was trying to get out 1733 01:11:50,880 --> 01:11:52,000 last week. It really I [clears throat] 1734 01:11:52,000 --> 01:11:53,679 mean it was wind. They couldn't get out 1735 01:11:53,679 --> 01:11:55,760 and get samples.

Um you all 1953 01:20:53,440 --> 01:20:55,600 are certainly the experts on this and so 1954 01:20:55,600 --> 01:20:57,440 I appreciate um Ben's done a really good 1955 01:20:57,440 --> 01:20:59,600 job looping me in and I've been trying 1956 01:20:59,600 --> 01:21:01,600 uh to be a more regular presence at your 1957 01:21:01,600 --> 01:21:03,520 meetings and to be in the loop as these 1958 01:21:03,520 --> 01:21:05,679 decisions are made and so I'm happy to 1959 01:21:05,679 --> 01:21:07,840 remain in that role. I don't think that 1960 01:21:07,840 --> 01:21:10,080 I need a voting role. Um I just like to 1961 01:21:10,080 --> 01:21:12,320 be advisory and and know what's going on 1962 01:21:12,320 --> 01:21:16,800 so I can speak um well to the subject. 1963 01:21:16,800 --> 01:21:18,400 >> And I' I'd also just add one other 1964 01:21:18,400 --> 01:21:19,920 thing. You know, the commissioner's 1965 01:21:19,920 --> 01:21:22,239 office has the ability to, you know, 1966 01:21:22,239 --> 01:21:24,480 tell any division to do something or not 1967 01:21:24,480 --> 01:21:26,080 do something. And so I think it's also 1968 01:21:26,080 --> 01:21:28,000 important that, you know, they maintain 1969 01:21:28,000 --> 01:21:29,600 that ability. We've never run into a 1970 01:21:29,600 --> 01:21:31,440 situation yet where we've had to where I 1971 01:21:31,440 --> 01:21:33,120 think they've had to use that power. But 1972 01:21:33,120 --> 01:21:34,800 I think that that gives them an option 1973 01:21:34,800 --> 01:21:36,640 if they're not in a voting capacity here 1974 01:21:36,640 --> 01:21:38,560 to be able to, you know, exercise that 1975 01:21:38,560 --> 01:21:40,320 role as well. So I think it's a good 1976 01:21:40,320 --> 01:21:41,520 set. 1977 01:21:41,520 --> 01:21:44,000 >> Is that within the DNR or across the 1978 01:21:44,000 --> 01:21:45,199 state? 1979 01:21:45,199 --> 01:21:47,040 >> I don't have to answer that, but the the 1980 01:21:47,040 --> 01:21:49,600 code originally I think was it excluded 1981 01:21:49,600 --> 01:21:51,199 certain agencies, but I think was you 1982 01:21:51,199 --> 01:21:53,760 know obviously relation 1983 01:21:53,760 --> 01:21:56,320 they have some authority that 1984 01:21:56,320 --> 01:21:58,159 >> Yeah.
