And then 209 00:11:02,399 --> 00:11:05,600 Caron Cat Ring at USU um is taking about 210 00:11:05,600 --> 00:11:08,959 the last 10-15 years of work that she's 211 00:11:08,959 --> 00:11:11,839 done um with reveation of Great Salt 212 00:11:11,839 --> 00:11:14,079 Lake wetlands and making it so it's much 213 00:11:14,079 --> 00:11:17,360 more accessible for um decision makers 214 00:11:17,360 --> 00:11:19,600 around the lake, wetland managers, uh 215 00:11:19,600 --> 00:11:21,040 private land owners upland who are 216 00:11:21,040 --> 00:11:23,200 trying to figure out after frag what 217 00:11:23,200 --> 00:11:27,920 next. Um so so some tools to help um 218 00:11:27,920 --> 00:11:30,399 people look at that. If you take a look 219 00:11:30,399 --> 00:11:33,040 at the total funding, we awarded about 220 00:11:33,040 --> 00:11:35,360 $370,000. 221 00:11:35,360 --> 00:11:38,880 Um, usually we award about we award 222 00:11:38,880 --> 00:11:41,760 $500,000. So, I just wanted to to take a 223 00:11:41,760 --> 00:11:43,200 moment to explain this. You remember 224 00:11:43,200 --> 00:11:46,399 that last year we started accepting both 225 00:11:46,399 --> 00:11:49,519 one and two-year projects. And so, this 226 00:11:49,519 --> 00:11:52,079 is the end of the first 227 00:11:52,079 --> 00:11:55,200 of year one of the first time we've done 228 00:11:55,200 --> 00:11:57,440 two-year projects. Um, so at our meeting 229 00:11:57,440 --> 00:11:59,760 in September, I'd like to spend do spend 230 00:11:59,760 --> 00:12:01,040 a little time doing a little bit of a 231 00:12:01,040 --> 00:12:03,040 post-mortem. How did that go? What do we 232 00:12:03,040 --> 00:12:06,639 need to adjust something? Um, 233 00:12:06,639 --> 00:12:09,920 and uh, you know, so hearing about that. 234 00:12:09,920 --> 00:12:12,399 So, usually it's 500,000, but what we've 235 00:12:12,399 --> 00:12:14,160 done the past two years is split it 236 00:12:14,160 --> 00:12:16,959 across two years. So, we've awarded um 237 00:12:16,959 --> 00:12:18,639 $250,000 238 00:12:18,639 --> 00:12:22,320 of this year and then we awarded 239 00:12:22,320 --> 00:12:24,959 $250,000 of next year's funds. And then 240 00:12:24,959 --> 00:12:27,279 it layered on. So this year we had the 241 00:12:27,279 --> 00:12:29,760 other 250,000 to award for this coming 242 00:12:29,760 --> 00:12:33,680 fiscal year and then 200 for the 250 for 243 00:12:33,680 --> 00:12:35,760 the year after that. What happened with 244 00:12:35,760 --> 00:12:37,519 this was it was kind of interesting just 245 00:12:37,519 --> 00:12:40,320 the way the projects fell out. Um we 246 00:12:40,320 --> 00:12:43,920 awarded all 250 for fiscal year 27. We 247 00:12:43,920 --> 00:12:45,279 maxed out the funding for this coming 248 00:12:45,279 --> 00:12:47,760 year, but just the way the funding was 249 00:12:47,760 --> 00:12:49,360 spread across these projects for year 250 00:12:49,360 --> 00:12:52,720 one and year two. um we only awarded I 251 00:12:52,720 --> 00:12:55,440 mean whatever the rest of it is $119,000 252 00:12:55,440 --> 00:12:58,480 for fiscal year 28. Um so what it looks 253 00:12:58,480 --> 00:13:00,959 like is I mean what we did is we ended 254 00:13:00,959 --> 00:13:03,120 up awarding less money than normal 255 00:13:03,120 --> 00:13:05,600 because there was more money left in 256 00:13:05,600 --> 00:13:08,399 year two in fiscal year 28 257 00:13:08,399 --> 00:13:11,120 um than we you know had thought there 258 00:13:11,120 --> 00:13:13,440 might be. So the bad news is you know it 259 00:13:13,440 --> 00:13:14,720 looks like a lower amount this year. The 260 00:13:14,720 --> 00:13:17,120 good news is next year when we open the 261 00:13:17,120 --> 00:13:20,000 grant process, which will be this fall, 262 00:13:20,000 --> 00:13:23,040 um for fiscal year 28 projects, 263 00:13:23,040 --> 00:13:25,279 uh 27 28. Wait, I'm losing track of my 264 00:13:25,279 --> 00:13:28,720 years. 28. Um 265 00:13:28,720 --> 00:13:30,880 we will be able to award more money than 266 00:13:30,880 --> 00:13:33,519 normal um because we'll have extra money 267 00:13:33,519 --> 00:13:35,600 in next year's pot, if that makes sense. 268 00:13:35,600 --> 00:13:37,440 If you have questions about that, let me 269 00:13:37,440 --> 00:13:39,920 know. 270 00:13:39,920 --> 00:13:45,670 A couple other updates. Um, 271 00:13:45,680 --> 00:13:48,240 for me, Great Salt Lake Advisory 272 00:13:48,240 --> 00:13:52,560 Council, um, is having its I'm not sure 273 00:13:52,560 --> 00:13:54,639 what the official term for this is, but 274 00:13:54,639 --> 00:13:59,920 it in its statute, it has, um, a sunset 275 00:13:59,920 --> 00:14:02,959 that um, unless it's renewed, it will 276 00:14:02,959 --> 00:14:04,800 sunset. So, it's having its sunset 277 00:14:04,800 --> 00:14:07,519 hearing at the natural resources 278 00:14:07,519 --> 00:14:11,440 um intram subcommittee meeting in May. 279 00:14:11,440 --> 00:14:12,720 So, if you're interested in that, you 280 00:14:12,720 --> 00:14:15,920 can talk to me about more details. Um I 281 00:14:15,920 --> 00:14:18,399 would and um there, you know, they're 282 00:14:18,399 --> 00:14:19,600 just hearing about what the work that 283 00:14:19,600 --> 00:14:21,120 it's done and thinking about how it 284 00:14:21,120 --> 00:14:23,199 looks going forward. 285 00:14:23,199 --> 00:14:24,720 Um one other update, the Solinity 286 00:14:24,720 --> 00:14:26,399 Advisory Council, we bumped the meeting 287 00:14:26,399 --> 00:14:29,760 from this Thursday to the 27th. It's a 288 00:14:29,760 --> 00:14:32,720 Wednesday at the end of the month and 289 00:14:32,720 --> 00:14:35,760 we're going to be looking at actually um 290 00:14:35,760 --> 00:14:37,519 it'll be a continuation of the 291 00:14:37,519 --> 00:14:39,360 conversation that we'll be having today 292 00:14:39,360 --> 00:14:42,480 with Christine and Gary um which is a 293 00:14:42,480 --> 00:14:45,120 really important look at uh how 294 00:14:45,120 --> 00:14:47,040 nutrients are moving in the lake. So 295 00:14:47,040 --> 00:14:53,600 this is sort of an emerging issue that um we're I mean most of us are new 296 00:14:53,600 --> 00:14:56,959 to. So, we're we're diving to that um in 297 00:14:56,959 --> 00:14:58,720 the salinity advisory council meeting 298 00:14:58,720 --> 00:15:01,839 and really thinking um about 299 00:15:01,839 --> 00:15:05,279 implications for the burm this year. So, 300 00:15:05,279 --> 00:15:09,680 come to that. That's going to be a winner. 301 00:15:09,680 --> 00:15:11,440 Um are there any other updates that 302 00:15:11,440 --> 00:15:13,279 anyone would like to share before we 303 00:15:13,279 --> 00:15:20,389 dive into today's presentations? 304 00:15:20,399 --> 00:15:26,310 Okay, great. Did I stop sharing? 305 00:15:26,320 --> 00:15:29,279 Okay. On our agenda today, we've got um 306 00:15:29,279 --> 00:15:31,680 two folks. If you came to the Great Salt 307 00:15:31,680 --> 00:15:35,040 Lake issues uh forum last week, you got 308 00:15:35,040 --> 00:15:38,079 sort of a a teaser for this. Um so today 309 00:15:38,079 --> 00:15:40,079 Gary Bolovski from University of Notre 310 00:15:40,079 --> 00:15:43,600 Dame and Christine Ramsey from USGS are 311 00:15:43,600 --> 00:15:46,240 talking to us in more detail about um 312 00:15:46,240 --> 00:15:48,240 what they're what they've been seeing 313 00:15:48,240 --> 00:15:52,079 and calculating um with nutrient 314 00:15:52,079 --> 00:15:55,759 um flows in Great Salt Lake. So Gary 315 00:15:55,759 --> 00:15:59,189 should be online 316 00:15:59,199 --> 00:16:03,350 and 317 00:16:03,360 --> 00:16:05,199 if you are Gary can you hear us? Can we 318 00:16:05,199 --> 00:16:16,710 hear you? 319 00:16:16,720 --> 00:16:27,430 Nope. 320 00:16:27,440 --> 00:16:31,350 Yeah, 321 00:16:31,360 --> 00:16:35,839 » Gary, if it's okay with you, we will 322 00:16:35,839 --> 00:16:38,880 Hey, now we see you. 323 00:16:38,880 --> 00:16:45,910 I mean, we can see your screen. 324 00:16:45,920 --> 00:16:47,040 » Can you hear me now? 325 00:16:47,040 --> 00:16:48,560 >> Yes. 326 00:16:48,560 --> 00:16:51,600 >> Okay. Uh the the link you sent me only 327 00:16:51,600 --> 00:16:54,639 allowed me to um 328 00:16:54,639 --> 00:16:57,680 uh to listen. 329 00:16:57,680 --> 00:17:00,399 So 330 00:17:00,399 --> 00:17:02,160 >> great.

It's just 336 00:17:31,600 --> 00:17:43,590 being quite slow for me. 337 00:17:43,600 --> 00:17:48,070 » Can you see that? 338 00:17:48,080 --> 00:17:49,679 Nope, 339 00:17:49,679 --> 00:18:01,029 it's not coming through. 340 00:18:01,039 --> 00:18:10,310 Nope. Let's see. 341 00:18:10,320 --> 00:18:15,990 There we go. 342 00:18:16,000 --> 00:18:16,799 How about 343 00:18:16,799 --> 00:18:17,360 >> Okay. 344 00:18:17,360 --> 00:18:18,960 >> How about that? Can you see mine? 345 00:18:18,960 --> 00:18:21,200 >> That's That's fine. I can see yours now. 346 00:18:21,200 --> 00:18:28,630 >> Great. Okay. Now, 347 00:18:28,640 --> 00:18:30,799 here we go. Okay. 348 00:18:30,799 --> 00:18:32,857 >> Okay. So, you're going to control it. 349 00:18:32,857 --> 00:18:34,799 [snorts] 350 00:18:34,799 --> 00:18:35,440 >> Yes. 351 00:18:35,440 --> 00:18:36,080 >> Right. 352 00:18:36,080 --> 00:18:39,510 >> Okay. 353 00:18:39,520 --> 00:18:42,000 » All right. Can we have the next slide? 354 00:18:42,000 --> 00:18:44,640 >> Yes. Although it's not showing the right 355 00:18:44,640 --> 00:18:46,400 one. 356 00:18:46,400 --> 00:18:49,280 Hold please. [sighs] 357 00:18:49,280 --> 00:18:52,000 >> Technology. 358 00:18:52,000 --> 00:18:55,200 All right. Um, so over the last three 359 00:18:55,200 --> 00:18:59,840 years, we've uh conducted uh experiments 360 00:18:59,840 --> 00:19:02,559 to be able to do nutrient budgets within 361 00:19:02,559 --> 00:19:04,960 the south arm of the lake. And these 362 00:19:04,960 --> 00:19:08,400 experiments have dealt with um looking 363 00:19:08,400 --> 00:19:11,600 at the decomposition rate, the fall rate 364 00:19:11,600 --> 00:19:15,840 through the water column and how um and 365 00:19:15,840 --> 00:19:18,720 the chemical composition of various uh 366 00:19:18,720 --> 00:19:21,360 biological materials in the lake. And 367 00:19:21,360 --> 00:19:23,039 with this, we've been able to put 368 00:19:23,039 --> 00:19:26,080 together um nutrient budgets for the 369 00:19:26,080 --> 00:19:30,640 south arm of the lake. and a lot a lot 370 00:19:30,640 --> 00:19:33,440 of the material ends up in the in the 371 00:19:33,440 --> 00:19:38,240 benthic zone and um 372 00:19:38,240 --> 00:19:40,880 that that poses problems in terms of the 373 00:19:40,880 --> 00:19:43,200 release of that from the benthic zone 374 00:19:43,200 --> 00:19:47,039 into the water column. However, after 375 00:19:47,039 --> 00:19:49,039 doing all of the calculations and 376 00:19:49,039 --> 00:19:55,750 everything, next slide, 377 00:19:55,760 --> 00:19:59,280 uh the results are very promising. Uh 378 00:19:59,280 --> 00:20:02,080 first, the budgets um in the pelagic 379 00:20:02,080 --> 00:20:05,039 zone and the benthic zones are nearly 380 00:20:05,039 --> 00:20:07,520 balanced, which is what you'd expect. In 381 00:20:07,520 --> 00:20:10,640 other words, the ecosystem is in some 382 00:20:10,640 --> 00:20:13,039 sort of I don't want to say equilibrium, 383 00:20:13,039 --> 00:20:15,520 but at least on the short term, on an 384 00:20:15,520 --> 00:20:18,160 annual basis, it seems that you're 385 00:20:18,160 --> 00:20:20,880 releasing certain amounts of nutrients 386 00:20:20,880 --> 00:20:24,160 at the same rate that they're that 387 00:20:24,160 --> 00:20:26,640 they're being used up within the lake. 388 00:20:26,640 --> 00:20:28,720 Now, the most important nutrient, let me 389 00:20:28,720 --> 00:20:31,440 point out right now, is nitrogen. 390 00:20:31,440 --> 00:20:34,240 appears to be the limiting 391 00:20:34,240 --> 00:20:37,039 nutrient for phytolanton production. 392 00:20:37,039 --> 00:20:39,840 and for the production of the the 393 00:20:39,840 --> 00:20:48,559 photosynthesis in the microbialite uh uh community. Now this could change over 394 00:20:48,559 --> 00:20:51,280 time with phosphorus becoming a limiting 395 00:20:51,280 --> 00:20:54,559 nutrient or both of them working in uh 396 00:20:54,559 --> 00:20:57,679 coordination to limit uh production but 397 00:20:57,679 --> 00:21:00,159 at least at present it seems nitrogen is 398 00:21:00,159 --> 00:21:04,870 the limiting nutrient. Next. 399 00:21:04,880 --> 00:21:07,440 Okay, we can test these results and 400 00:21:07,440 --> 00:21:09,600 Christine I'm sure may be talking a 401 00:21:09,600 --> 00:21:12,000 little more about this, but if we look 402 00:21:12,000 --> 00:21:14,240 at from her experiments the 403 00:21:14,240 --> 00:21:17,200 sedimentation in traps that she's put 404 00:21:17,200 --> 00:21:20,080 out in the lake for June and July, 405 00:21:20,080 --> 00:21:22,640 um the amount of total dissolved 406 00:21:22,640 --> 00:21:25,600 nitrogen or no, the mass that appears in 407 00:21:25,600 --> 00:21:28,240 the sediment traps that she's measuring 408 00:21:28,240 --> 00:21:29,840 is 409 00:21:29,840 --> 00:21:34,159 about 2.3 g per meter squared per day. 410 00:21:34,159 --> 00:21:37,440 And just based on the uh fecal pellet 411 00:21:37,440 --> 00:21:41,280 snowfall from shrimp uh artmia in the 412 00:21:41,280 --> 00:21:44,960 lake, we calculate 1.9 grams per meter 413 00:21:44,960 --> 00:21:47,600 squared per day. And that term snowfall 414 00:21:47,600 --> 00:21:50,240 is from marine studies uh where they 415 00:21:50,240 --> 00:21:52,320 measure uh it's the term they use for 416 00:21:52,320 --> 00:21:57,120 the uh sinking of fecal pellets from uh 417 00:21:57,120 --> 00:22:02,000 zoplankton in the water column. Next, 418 00:22:02,000 --> 00:22:04,880 when we observed the observed total 419 00:22:04,880 --> 00:22:07,679 dissolved nitrogen that Christine 420 00:22:07,679 --> 00:22:10,240 probably will be talking about today is 421 00:22:10,240 --> 00:22:12,400 4.21 422 00:22:12,400 --> 00:22:16,320 mg per liter and the total dissolved 423 00:22:16,320 --> 00:22:19,679 nitrogen that the um budget comes up 424 00:22:19,679 --> 00:22:22,480 with is 4.15 425 00:22:22,480 --> 00:22:25,760 mg per liter. So we're getting similar 426 00:22:25,760 --> 00:22:28,400 results between what's being measured by 427 00:22:28,400 --> 00:22:32,559 US Geological Survey and what the budget 428 00:22:32,559 --> 00:22:37,679 excuse me uh is uh estimating next 429 00:22:37,679 --> 00:22:40,159 and the same thing can be observed for 430 00:22:40,159 --> 00:22:43,679 phosphorus dissolved phosphorus and we 431 00:22:43,679 --> 00:22:47,679 um the observation from USGS is 2.295 432 00:22:47,679 --> 00:22:51,919 295 mg per liter and the budget that we 433 00:22:51,919 --> 00:22:55,840 get is 26 millgrams per liter. So we 434 00:22:55,840 --> 00:22:58,000 were very pleased with these results. 435 00:22:58,000 --> 00:23:00,960 Next slide. 436 00:23:00,960 --> 00:23:02,960 Except one thing that we hadn't 437 00:23:02,960 --> 00:23:05,840 considered was because we thought that 438 00:23:05,840 --> 00:23:08,159 the south arm of the lake was basically 439 00:23:08,159 --> 00:23:11,840 a single was a unit independent of the 440 00:23:11,840 --> 00:23:14,720 north arm of the lake. We did did not 441 00:23:14,720 --> 00:23:17,520 include the transport of material 442 00:23:17,520 --> 00:23:20,000 between the south arm to the north arm 443 00:23:20,000 --> 00:23:22,480 and return of material from the north 444 00:23:22,480 --> 00:23:27,600 arm to the south arm. So this became a 445 00:23:27,600 --> 00:23:30,799 concern to us when we started thinking 446 00:23:30,799 --> 00:23:33,280 about the burm that had been con uh 447 00:23:33,280 --> 00:23:37,200 constructed that restricted the movement 448 00:23:37,200 --> 00:23:40,240 of water from the south arm to the north 449 00:23:40,240 --> 00:23:43,039 arm and particularly restricted the 450 00:23:43,039 --> 00:23:45,679 movement of water from the north arm to 451 00:23:45,679 --> 00:23:47,760 the south arm. 452 00:23:47,760 --> 00:23:51,110 Next slide. 453 00:23:51,120 --> 00:23:53,600 So this burm was constructed and we can 454 00:23:53,600 --> 00:23:56,400 see that if we look at the ratio of the 455 00:23:56,400 --> 00:23:59,520 flow between north to south and south to 456 00:23:59,520 --> 00:24:02,480 north on the y ais and we look at 457 00:24:02,480 --> 00:24:05,919 measurements over time of that ratio 458 00:24:05,919 --> 00:24:08,240 where we have complete annual 459 00:24:08,240 --> 00:24:10,880 measurements monthly measurements of the 460 00:24:10,880 --> 00:24:13,919 flow. We can see that before the burm 461 00:24:13,919 --> 00:24:18,400 was constructed and took effect in 2023 462 00:24:18,400 --> 00:24:20,559 that there was considerable flow 463 00:24:20,559 --> 00:24:22,799 exchanged between the two arms of the 464 00:24:22,799 --> 00:24:25,279 lake. After the construction of that 465 00:24:25,279 --> 00:24:29,600 burm in 2022 and essentially its impact 466 00:24:29,600 --> 00:24:31,840 starting in 2023, 467 00:24:31,840 --> 00:24:35,120 the return flow from the north arm to 468 00:24:35,120 --> 00:24:38,799 the south arm was drastically reduced. 469 00:24:38,799 --> 00:24:42,149 Next slide. 470 00:24:42,159 --> 00:24:45,520 Well, looking at these data over time or 471 00:24:45,520 --> 00:24:47,520 looking at data from the south arm of 472 00:24:47,520 --> 00:24:51,840 the lake over time, we we were uh 473 00:24:51,840 --> 00:24:55,279 surprised in seeing that in 2024 to 474 00:24:55,279 --> 00:24:59,279 2025, we got a dramatic decline in the 475 00:24:59,279 --> 00:25:02,400 annual chlorophyll a measurements for 476 00:25:02,400 --> 00:25:05,600 the lake. Prior to that time, you can 477 00:25:05,600 --> 00:25:08,640 see the green bars, we had higher 478 00:25:08,640 --> 00:25:12,799 chlorophyll A and 2024 and 2025, we 479 00:25:12,799 --> 00:25:15,360 started to see a decrease in the 480 00:25:15,360 --> 00:25:18,159 chlorophyll a comp uh produced in the 481 00:25:18,159 --> 00:25:20,480 south arm of the lake. And this was 482 00:25:20,480 --> 00:25:22,960 bothersome. It's because this 483 00:25:22,960 --> 00:25:25,919 phytolanton chlorophyll a in the south 484 00:25:25,919 --> 00:25:30,720 arm is what is controlling driving the 485 00:25:30,720 --> 00:25:33,120 whole production within the pelagic 486 00:25:33,120 --> 00:25:37,360 stone. If we look at the chlorophyll a 487 00:25:37,360 --> 00:25:40,559 per cell in the phytolanton 488 00:25:40,559 --> 00:25:44,000 the green line shows by month what the 489 00:25:44,000 --> 00:25:45,760 chlorophyll content is of the 490 00:25:45,760 --> 00:25:49,600 phytolanton cells. The brown line below 491 00:25:49,600 --> 00:25:52,480 points out what is the chlorophyll a per 492 00:25:52,480 --> 00:25:56,960 cell after the berm was constructed and 493 00:25:56,960 --> 00:26:00,000 went into started to change the flow 494 00:26:00,000 --> 00:26:01,840 rates. 495 00:26:01,840 --> 00:26:05,120 You can see that the cell chlorophyll a 496 00:26:05,120 --> 00:26:09,520 component is considerably reduced after 497 00:26:09,520 --> 00:26:12,880 the burm was put in place. Now this burm 498 00:26:12,880 --> 00:26:15,600 was placed there to try to control the 499 00:26:15,600 --> 00:26:18,000 salinity in the south arm of the lake 500 00:26:18,000 --> 00:26:20,000 which was getting too high under the 501 00:26:20,000 --> 00:26:22,320 current drought conditions and this was 502 00:26:22,320 --> 00:26:25,039 important to maintain the productivity 503 00:26:25,039 --> 00:26:28,240 of that south arm ecosystem. 504 00:26:28,240 --> 00:26:31,360 However, the un the unanticipated 505 00:26:31,360 --> 00:26:34,640 consequence of this berm controlling 506 00:26:34,640 --> 00:26:38,559 salinity was to change the productivity 507 00:26:38,559 --> 00:26:42,240 in the south arm by returning the amount 508 00:26:42,240 --> 00:26:45,760 of nitrogen from the north arm to the 509 00:26:45,760 --> 00:26:48,320 south arm. 510 00:26:48,320 --> 00:26:52,390 Next slide. 511 00:26:52,400 --> 00:26:55,279 So constructing a simple 512 00:26:55,279 --> 00:26:57,520 back of the envelope calculations of 513 00:26:57,520 --> 00:27:00,640 flow of water between the south to the 514 00:27:00,640 --> 00:27:03,279 north arm, the green arrow and the 515 00:27:03,279 --> 00:27:06,400 return from the north arm to the south 516 00:27:06,400 --> 00:27:07,919 arm 517 00:27:07,919 --> 00:27:09,679 about 518 00:27:09,679 --> 00:27:12,880 for the period without the burm and then 519 00:27:12,880 --> 00:27:15,679 solving that we saw that the equilibrium 520 00:27:15,679 --> 00:27:18,159 that was obtained in the south arm in 521 00:27:18,159 --> 00:27:22,320 terms of nitrogen per liter was matched 522 00:27:22,320 --> 00:27:25,200 up with what was predicted in the budget 523 00:27:25,200 --> 00:27:27,919 and very similar to what USGS was 524 00:27:27,919 --> 00:27:31,279 predicting or measuring in the south arm 525 00:27:31,279 --> 00:27:36,559 and that's 4.15 mg per liter. 526 00:27:36,559 --> 00:27:38,880 However, if you look at the north arm, 527 00:27:38,880 --> 00:27:41,919 the nitrogen content in the north arm is 528 00:27:41,919 --> 00:27:47,279 9.96 mg per liter. And USGS, and I'm 529 00:27:47,279 --> 00:27:48,880 sure Christine will be talking about 530 00:27:48,880 --> 00:27:52,559 this, USGS measurements come up with a 531 00:27:52,559 --> 00:27:55,120 value between two to three times greater 532 00:27:55,120 --> 00:27:59,679 nitrogen content in the north arm. 533 00:27:59,679 --> 00:28:01,679 Our estimate here on these back of the 534 00:28:01,679 --> 00:28:04,799 envelope calculations is about 2.4 times 535 00:28:04,799 --> 00:28:08,640 greater nitrogen content at 9.96 536 00:28:08,640 --> 01:01:02,710 milligrams per liter. 537 01:01:02,720 --> 01:01:05,920 set at the new breach. So this is again 538 01:01:05,920 --> 01:01:07,520 where that exchange is happening where 539 01:01:07,520 --> 01:01:10,559 USGS heavily instruments uh this area to 540 01:01:10,559 --> 01:01:12,079 monitor both the discharge and 541 01:01:12,079 --> 01:01:14,079 concentrations of constituents so we can 542 01:01:14,079 --> 01:01:16,880 uh estimate the fluxes happening here. 543 01:01:16,880 --> 01:01:19,200 Um this is analysis done by Scott. So 544 01:01:19,200 --> 01:01:21,680 thank you for sharing your work here. Um 545 01:01:21,680 --> 01:01:23,440 these are total dissolved nitrogen 546 01:01:23,440 --> 01:01:25,599 concentrations. This is a plot of that. 547 01:01:25,599 --> 01:01:28,480 And the red dots indicate north to south 548 01:01:28,480 --> 01:01:30,640 concentrations from about 2017 to 549 01:01:30,640 --> 01:01:33,119 present. The green dots indicate south 550 01:01:33,119 --> 01:01:34,720 to north. And this is really just to 551 01:01:34,720 --> 01:01:36,799 illustrate the magnitude differences in 552 01:01:36,799 --> 01:01:38,480 concentrations between each of these 553 01:01:38,480 --> 01:01:40,880 arms of the lake. So in the south arm on 554 01:01:40,880 --> 01:01:43,040 average we have about 4.3 milligram per 555 01:01:43,040 --> 01:01:45,119 liter nitrogen. In the north arm what's 556 01:01:45,119 --> 01:01:47,280 coming to the south it's about 6.9 557 01:01:47,280 --> 01:01:49,520 milligrams per liter. So about one and a 558 01:01:49,520 --> 01:01:52,319 half times greater um concentrations uh 559 01:01:52,319 --> 01:01:53,760 in the north arm coming back to the 560 01:01:53,760 --> 01:01:55,599 south than in what is leaving. So that 561 01:01:55,599 --> 01:01:57,119 north arm really packs a punch. It's 562 01:01:57,119 --> 01:01:58,880 more concentrated than the south arm 563 01:01:58,880 --> 01:02:00,799 water. 564 01:02:00,799 --> 01:02:02,640 And if we look at loads, so pairing 565 01:02:02,640 --> 01:02:04,880 those concentrations with a discharge 566 01:02:04,880 --> 01:02:07,520 estimate to get a mass flux. Uh we can 567 01:02:07,520 --> 01:02:10,160 see kind of just compare the pre and 568 01:02:10,160 --> 01:02:13,040 postm modification time period. So prior 569 01:02:13,040 --> 01:02:15,200 to burm modification um which is right 570 01:02:15,200 --> 01:02:18,960 about here in 2020 summer of 2022 you 571 01:02:18,960 --> 01:02:22,559 can see um how north to south and south 572 01:02:22,559 --> 01:02:26,000 to north fluxes tended to be um a bit 573 01:02:26,000 --> 01:02:29,760 more uh in sync or a a bit more equal 574 01:02:29,760 --> 01:02:31,760 after burm modification when we really 575 01:02:31,760 --> 01:02:33,599 cut off that northarm arm flow. You can 576 01:02:33,599 --> 01:02:35,200 just see those go to zero. Essentially 577 01:02:35,200 --> 01:02:37,599 there was no flow nothing coming in. So 578 01:02:37,599 --> 01:02:40,319 we just see a really stark reduction in 579 01:02:40,319 --> 01:02:42,640 the the flux um at the new breach as you 580 01:02:42,640 --> 01:02:44,480 might expect. So the pre-burner 581 01:02:44,480 --> 01:02:46,240 modification fluxes were on the order of 582 01:02:46,240 --> 01:02:48,480 six tons per day. After that we're 583 01:02:48,480 --> 01:02:50,400 looking at less than one ton per day. 584 01:02:50,400 --> 01:02:52,559 And if we extrapolate those values on an 585 01:02:52,559 --> 01:02:54,559 annual basis, we're approaching about 586 01:02:54,559 --> 01:02:56,960 2,000 u ton per year reduction in 587 01:02:56,960 --> 01:03:00,559 nitrogen coming back into the south arm. 588 01:03:00,559 --> 01:03:02,559 If we do a similar exercise for total 589 01:03:02,559 --> 01:03:05,040 dissolved phosphorus, we can see that um 590 01:03:05,040 --> 01:03:06,880 concentrations for total dissolved 591 01:03:06,880 --> 01:03:09,119 phosphorus in the north arm are higher 592 01:03:09,119 --> 01:03:10,799 than in the south like you might expect. 593 01:03:10,799 --> 01:03:13,680 Very similar for nitrogen. And pairing 594 01:03:13,680 --> 01:03:15,599 those with fluxes, we can see how prior 595 01:03:15,599 --> 01:03:17,280 to the bur modification when we had 596 01:03:17,280 --> 01:03:19,839 birectional exchange, um we were getting 597 01:03:19,839 --> 01:03:23,599 about 3 million or sorry.3 tons per day 598 01:03:23,599 --> 01:03:25,760 uh coming from north to south in 599 01:03:25,760 --> 01:03:27,520 phosphorus and then after that it really 600 01:03:27,520 --> 01:03:31,440 tapered off to almost nothing. 601 01:03:31,440 --> 01:03:33,039 And then looking at this a slightly 602 01:03:33,039 --> 01:03:34,400 different way, if we just look at the 603 01:03:34,400 --> 01:03:37,119 nut net nutrient flux. So comparing both 604 01:03:37,119 --> 01:03:39,599 what's going out and what's coming in, 605 01:03:39,599 --> 01:03:41,920 um we can see after burn modification 606 01:03:41,920 --> 01:03:44,000 shown in this salmon color, we had a 607 01:03:44,000 --> 01:03:46,559 higher great uh a greater nitrogen loss. 608 01:03:46,559 --> 01:03:48,079 That's kind of what that shift upward in 609 01:03:48,079 --> 01:03:50,000 the box plot indicates. We had more 610 01:03:50,000 --> 01:03:52,240 nitrogen loss to the north arm as you 611 01:03:52,240 --> 01:03:53,680 might expect because the fluxes coming 612 01:03:53,680 --> 01:03:55,599 back in were shut off and we continue to 613 01:03:55,599 --> 01:03:57,920 export to the south. And if we kind of 614 01:03:57,920 --> 01:03:59,680 take an annual estimate of what that 615 01:03:59,680 --> 01:04:02,720 nitrogen reduction is over a period of 616 01:04:02,720 --> 01:04:04,880 well I'll do it in on an annual basis 617 01:04:04,880 --> 01:04:07,760 and and compare that to the mass in the 618 01:04:07,760 --> 01:04:10,000 south arm. So we're considering the 619 01:04:10,000 --> 01:04:12,079 resident nitrogen mass in the south arm 620 01:04:12,079 --> 01:04:14,720 as well as the volume that we get about 621 01:04:14,720 --> 01:04:17,200 we estimate that we get about a 0.1 to 2 622 01:04:17,200 --> 01:04:20,240 milligram per liter nitrogen decrease in 623 01:04:20,240 --> 01:04:21,920 the south arm. So essentially 624 01:04:21,920 --> 01:04:24,319 extrapolating what's that flux at the at 625 01:04:24,319 --> 01:04:26,640 the breach to the entire south arm what 626 01:04:26,640 --> 01:04:28,799 that would do to the resident salt mass 627 01:04:28,799 --> 01:04:30,880 um is is kind of what you get a 0.1 to 628 01:04:30,880 --> 01:04:32,799 point 2 milligram per liter decrease in 629 01:04:32,799 --> 01:04:35,039 south arm nitrogen extrapolated over 630 01:04:35,039 --> 01:04:36,559 multiple years because the effect of 631 01:04:36,559 --> 01:04:38,960 this is cumulative it's about a.5 632 01:04:38,960 --> 01:04:40,799 milligram per liter nitrogen decrease 633 01:04:40,799 --> 01:04:43,039 over um kind of the last three years 634 01:04:43,039 --> 01:04:45,280 which is in line with kind of what Gary 635 01:04:45,280 --> 01:04:47,920 had estimated and also what we we we 636 01:04:47,920 --> 01:04:50,240 observed in the change in um total 637 01:04:50,240 --> 01:04:52,160 dissolved nit rogen concentration after 638 01:04:52,160 --> 01:04:55,039 the berm was modified. So I'll just 639 01:04:55,039 --> 01:04:56,960 summarize kind of these exercises by 640 01:04:56,960 --> 01:04:59,200 saying we we used two independent data 641 01:04:59,200 --> 01:05:01,680 sets. The first uh using our nutrient 642 01:05:01,680 --> 01:05:04,319 data collected in the south arm to show 643 01:05:04,319 --> 01:05:06,240 or to estimate that there has been a 644 01:05:06,240 --> 01:05:08,079 statistically significant decrease in 645 01:05:08,079 --> 01:05:10,400 the nitrogen mass in the south arm after 646 01:05:10,400 --> 01:05:13,039 the burm was modified. And similarly if 647 01:05:13,039 --> 01:05:14,559 we look at fluxes happening at the 648 01:05:14,559 --> 01:05:16,290 brereech we kind of we measure 649 01:05:16,290 --> 01:05:17,680 [clears throat] that there has just been 650 01:05:17,680 --> 01:05:20,400 a decrease in flux or decrease in import 651 01:05:20,400 --> 01:05:22,880 of nitrogen coming in from uh the north 652 01:05:22,880 --> 01:05:24,559 arm 653 01:05:24,559 --> 01:05:26,720 and moving forward as as Angela 654 01:05:26,720 --> 01:05:28,720 mentioned this will be a topic of 655 01:05:28,720 --> 01:05:30,400 conversation in the solen next salinity 656 01:05:30,400 --> 01:05:32,480 advisory committee um what we've done 657 01:05:32,480 --> 01:05:35,359 for salinity to help us track salinity 658 01:05:35,359 --> 01:05:36,880 salt mass and volume and kind of 659 01:05:36,880 --> 01:05:38,960 integrate those variables is to come up 660 01:05:38,960 --> 01:05:40,559 with a plot like this which we call an 661 01:05:40,559 --> 01:05:42,079 isomass plot 662 01:05:42,079 --> 01:05:43,839 um where south arm elevation is shown on 663 01:05:43,839 --> 01:05:45,359 the y- axis and we have a volume 664 01:05:45,359 --> 01:05:47,599 weighted salinity estimate on the x- 665 01:05:47,599 --> 01:05:49,839 axis. And this kind of allows us to 666 01:05:49,839 --> 01:05:51,680 triangulate at any given time when we 667 01:05:51,680 --> 01:05:53,359 have most you know more recent 668 01:05:53,359 --> 01:05:54,880 measurements and say okay here's our 669 01:05:54,880 --> 01:05:56,559 salinity at a given time here's our 670 01:05:56,559 --> 01:05:58,799 elevation and here's our mass. Putting 671 01:05:58,799 --> 01:06:00,880 that in the context of targets that have 672 01:06:00,880 --> 01:06:02,880 been identified currently we're in a 673 01:06:02,880 --> 01:06:05,599 pretty good shape. um you know one with 674 01:06:05,599 --> 01:06:07,680 the target our optimal range identified 675 01:06:07,680 --> 01:06:09,920 as 90 to 160 grams per liter and we're 676 01:06:09,920 --> 01:06:13,039 sitting at about 120. So this framework 677 01:06:13,039 --> 01:06:15,440 um allows us to kind of know where we 678 01:06:15,440 --> 01:06:17,839 are. It also helps us to uh predict 679 01:06:17,839 --> 01:06:20,240 where we might go because as elevations 680 01:06:20,240 --> 01:06:22,160 go up for a given salt mass, we predict 681 01:06:22,160 --> 01:06:24,240 salinities will decrease as we move to 682 01:06:24,240 --> 01:06:26,480 the left on that y- axis and vice versa. 683 01:06:26,480 --> 01:06:28,160 If we're entering more of an evaporative 684 01:06:28,160 --> 01:06:30,480 season and we elevations go down, we can 685 01:06:30,480 --> 01:06:32,240 predict where we might end up in terms 686 01:06:32,240 --> 01:06:34,799 of salinity. So that this framework has 687 01:06:34,799 --> 01:06:36,640 been useful for salt and it was 688 01:06:36,640 --> 01:06:38,240 requested by solinity advisory committee 689 01:06:38,240 --> 01:06:40,160 that we kind of build something like 690 01:06:40,160 --> 01:06:42,720 this for nutrients and so I just here's 691 01:06:42,720 --> 01:06:45,599 the first cut at that um is trying to 692 01:06:45,599 --> 01:06:47,839 get at our ISOs plot for nutrients and 693 01:06:47,839 --> 01:06:49,760 exploring whether this framework is also 694 01:06:49,760 --> 01:06:51,599 useful for something like nutrients or 695 01:06:51,599 --> 01:06:55,680 any constituent that that the state or others identify as important for 696 01:06:55,680 --> 01:06:57,839 trying to track and understand um 697 01:06:57,839 --> 01:06:59,599 constituent fluxes and the status of 698 01:06:59,599 --> 01:07:01,760 mass in the south arm. So similarly 699 01:07:01,760 --> 01:07:03,440 we've got south arm elevation on the y- 700 01:07:03,440 --> 01:07:06,240 axis and a volume weighted in this case 701 01:07:06,240 --> 01:07:08,400 totals dissolved nitrogen uh 702 01:07:08,400 --> 01:07:11,280 concentration on the x axis and so the 703 01:07:11,280 --> 01:07:12,720 most recent data we have is from 704 01:07:12,720 --> 01:07:14,480 November 4th. So we can integrate where 705 01:07:14,480 --> 01:07:16,480 we were in terms of elevation where we 706 01:07:16,480 --> 01:07:19,440 were in terms of the um nitrogen 707 01:07:19,440 --> 01:07:21,280 concentration and the mass. So 708 01:07:21,280 --> 01:07:22,720 integrating kind of these three 709 01:07:22,720 --> 01:07:25,039 variables that have been helpful for the 710 01:07:25,039 --> 01:07:26,480 solenity advisory committee and division 711 01:07:26,480 --> 01:07:28,400 of forestry fine state lands as they try 712 01:07:28,400 --> 01:07:31,200 to manage the exchange the mass fluxes 713 01:07:31,200 --> 01:07:33,119 of various constituents in the south 714 01:07:33,119 --> 01:07:36,000 arm. Um and so as a first cut looking at 715 01:07:36,000 --> 01:07:38,480 this for nutrients um where we currently 716 01:07:38,480 --> 01:07:40,240 sit is kind of in the middle of the 717 01:07:40,240 --> 01:07:42,160 range of total dissolved nitrogen 718 01:07:42,160 --> 01:07:43,839 concentrations. And so this is actually 719 01:07:43,839 --> 01:07:45,680 something that I would love to explore 720 01:07:45,680 --> 01:07:47,280 with Gary or others who are interested 721 01:07:47,280 --> 01:07:49,680 is that um we've been here before. These 722 01:07:49,680 --> 01:07:51,440 total dissolved nitrogen concentrations 723 01:07:51,440 --> 01:07:54,000 are not anomalously low. They're kind of 724 01:07:54,000 --> 01:07:56,079 middle of the road. And so in the past 725 01:07:56,079 --> 01:07:58,160 where we've had similar nit total 726 01:07:58,160 --> 01:07:59,920 dissolved nitrogen concentrations, what 727 01:07:59,920 --> 01:08:02,079 has been the effect on the biota? Um 728 01:08:02,079 --> 01:08:03,760 because we're not we're kind of from 729 01:08:03,760 --> 01:08:06,400 what I can tell not at an extremely low 730 01:08:06,400 --> 01:08:08,160 nitrogen concentration relative to what 731 01:08:08,160 --> 01:08:10,480 we've measured in the past. 732 01:08:10,480 --> 01:08:12,720 In terms of mass in the South Arm, we do 733 01:08:12,720 --> 01:08:14,319 it does seem to me like we're kind of in 734 01:08:14,319 --> 01:08:16,159 the lower end of that distribution. If 735 01:08:16,159 --> 01:08:17,839 we sort of look at where we've been in 736 01:08:17,839 --> 01:08:20,799 the past around 30 to 35,000 tons, now 737 01:08:20,799 --> 01:08:22,880 we're sitting at around 30,000. So that 738 01:08:22,880 --> 01:08:24,960 does does look different and you know 739 01:08:24,960 --> 01:08:27,440 statistically is significantly lower. 740 01:08:27,440 --> 01:08:29,120 And then of course we are at the low end 741 01:08:29,120 --> 01:08:30,719 of a distribution in terms of lake 742 01:08:30,719 --> 01:08:32,880 elevation. So, um, this is just an 743 01:08:32,880 --> 01:08:35,279 initial framework to help us wrap our 744 01:08:35,279 --> 01:08:37,040 brain around this new constituent 745 01:08:37,040 --> 01:08:39,440 extending management considerations to 746 01:08:39,440 --> 01:08:41,600 more than just salt. Um, not sure if 747 01:08:41,600 --> 01:08:43,120 this will be useful yet, but it's a 748 01:08:43,120 --> 01:08:44,719 first stab at something that might be. 749 01:08:44,719 --> 01:08:46,799 So, with that, I will I'm happy to take 750 01:08:46,799 --> 01:08:49,040 any questions or clarify anything that 751 01:08:49,040 --> 01:08:55,910 might have been confusing. 752 01:08:55,920 --> 01:09:06,229 » Thank you, Christine. Questions? 753 01:09:06,239 --> 01:09:08,239 I got one. 754 01:09:08,239 --> 01:09:12,480 Um, so we've I think arrived at for 755 01:09:12,480 --> 01:09:16,560 salt. If you were to take one annual 756 01:09:16,560 --> 01:09:18,719 observation that you were going to use 757 01:09:18,719 --> 01:09:21,520 for long-term trends that you would use 758 01:09:21,520 --> 01:09:24,319 October, November to look at the total 759 01:09:24,319 --> 01:09:25,920 dissolved salt mass because it would 760 01:09:25,920 --> 01:09:28,159 incorporate the cumulative effects of 761 01:09:28,159 --> 01:09:32,400 runoff and then strong evaporation. 762 01:09:32,400 --> 01:09:36,960 Uh I'm wondering if there I if there is 763 01:09:36,960 --> 01:09:39,440 a time of the year given that nitrogen 764 01:09:39,440 --> 01:09:43,279 is so reactive salt the salt is too in 765 01:09:43,279 --> 01:09:45,759 this system I guess but um is there a 766 01:09:45,759 --> 01:09:48,319 time of if there was one sample a year 767 01:09:48,319 --> 01:09:50,159 that you could use to to look at 768 01:09:50,159 --> 01:09:53,040 long-term trends would it be the same or 769 01:09:53,040 --> 01:09:54,560 different? 770 01:09:54,560 --> 01:09:56,640 >> Good question. Um I guess I'll just 771 01:09:56,640 --> 01:09:58,000 start by saying and you know look 772 01:09:58,000 --> 01:09:59,520 working with these data they are much 773 01:09:59,520 --> 01:10:02,159 noisier than a salt concentration or a 774 01:10:02,159 --> 01:10:04,320 salt mass estimate. So that's for 775 01:10:04,320 --> 01:10:06,480 starters the data set is more variable 776 01:10:06,480 --> 01:10:08,640 and as you mentioned it's more reactive. 777 01:10:08,640 --> 01:10:11,040 So inorganic nitrogen is exchanging with 778 01:10:11,040 --> 01:10:13,760 the biota um decomposition is happening 779 01:10:13,760 --> 01:10:15,280 things are changing deep brine layer 780 01:10:15,280 --> 01:10:18,400 affects these things. Um I don't know 781 01:10:18,400 --> 01:10:21,120 yet. I think that it would be similar 782 01:10:21,120 --> 01:10:23,120 probably fall just because you remove 783 01:10:23,120 --> 01:10:24,880 hydraological variables that variance 784 01:10:24,880 --> 01:10:26,960 there. But I think we need to work with 785 01:10:26,960 --> 01:10:29,440 Gary and other biologists to really uh 786 01:10:29,440 --> 01:10:31,920 kind of home in on a time of year where 787 01:10:31,920 --> 01:10:33,520 we we would think those would be more 788 01:10:33,520 --> 01:10:35,679 stable. I will also say this initial 789 01:10:35,679 --> 01:10:38,480 framework that I have shared with you 790 01:10:38,480 --> 01:10:40,400 today is integrating the entire water 791 01:10:40,400 --> 01:10:43,520 column. So this volume weighted um 792 01:10:43,520 --> 01:10:49,360 concentration that I share is is uh is really including anything that might 793 01:10:49,360 --> 01:10:50,719 have historically been sequestered in 794 01:10:50,719 --> 01:10:52,800 the deep brine layer. And perhaps a more 795 01:10:52,800 --> 01:10:55,360 relevant uh framework would actually o 796 01:10:55,360 --> 01:10:57,360 be only looking at the concentration in 797 01:10:57,360 --> 01:10:58,719 the upper brine layer and how that 798 01:10:58,719 --> 01:11:00,000 changes through time and that's 799 01:11:00,000 --> 01:11:01,360 something we can easily do but I didn't 800 01:11:01,360 --> 01:11:03,360 have a chance to do that. Um, so there's 801 01:11:03,360 --> 01:11:04,880 I guess I'll just answer by saying I 802 01:11:04,880 --> 01:11:06,640 don't know. And there's additional uh 803 01:11:06,640 --> 01:11:08,960 considerations that we haven't really 804 01:11:08,960 --> 01:11:11,120 had to dive into for salt that we will 805 01:11:11,120 --> 01:11:12,480 for nutrients and I think we should do 806 01:11:12,480 --> 01:11:18,470 that pretty carefully. 807 01:11:18,480 --> 01:11:20,960 » Quick question out of curiosity. Do we 808 01:11:20,960 --> 01:11:23,040 know the nitrogen coming out of West 809 01:11:23,040 --> 01:11:25,760 Davis water treatment? 810 01:11:25,760 --> 01:11:27,840 >> I believe they're measuring it, but we 811 01:11:27,840 --> 01:11:29,920 have not analyzed those data. And in 812 01:11:29,920 --> 01:11:31,760 fact, it might it perhaps would be a 813 01:11:31,760 --> 01:11:33,760 worthwhile while well exercise for us to 814 01:11:33,760 --> 01:11:35,600 update the kind of mass balance that 815 01:11:35,600 --> 01:11:38,880 Hannah did and include that outflow. Um, 816 01:11:38,880 --> 01:11:43,430 but no, we haven't looked at that yet. 817 01:11:43,440 --> 01:11:44,880 » We have a couple of questions online. 818 01:11:44,880 --> 01:11:48,229 Alex, 819 01:11:48,239 --> 01:11:51,280 » hey Christine, Alex of Duke University. 820 01:11:51,280 --> 01:11:53,360 Um, really fascinating results. I'm 821 01:11:53,360 --> 01:11:55,840 really interested to see how this uh 822 01:11:55,840 --> 01:11:59,280 progresses. Um I'm curious if these 823 01:11:59,280 --> 01:12:01,520 uh nitrogen concentration data are 824 01:12:01,520 --> 01:12:05,679 available through from like the whole 825 01:12:05,679 --> 01:12:09,040 time range like through 2025 up on USGS 826 01:12:09,040 --> 01:12:10,239 website. Right now 827 01:12:10,239 --> 01:12:12,000 >> they're [snorts] not. Um so a 828 01:12:12,000 --> 01:12:13,840 complicating factor in this has been 829 01:12:13,840 --> 01:12:17,600 that we we switched labs because the 830 01:12:17,600 --> 01:12:20,560 USGS laboratory decided no longer to 831 01:12:20,560 --> 01:12:22,480 analyze hyperscaling nutrients. So in 832 01:12:22,480 --> 01:12:24,960 about 2023, sorry a long story, but they 833 01:12:24,960 --> 01:12:26,880 um essentially we've been in the middle 834 01:12:26,880 --> 01:12:29,280 of a transition into using a new 835 01:12:29,280 --> 01:12:32,320 laboratory which is not an insignificant 836 01:12:32,320 --> 01:12:34,239 task because we're dealing with hypers 837 01:12:34,239 --> 01:12:36,800 saline water as you know and so we have 838 01:12:36,800 --> 01:12:39,120 been doing a pretty rigorous an um 839 01:12:39,120 --> 01:12:41,520 evaluation of this new laboratory. We've 840 01:12:41,520 --> 01:12:43,280 been doing a number of comparisons and 841 01:12:43,280 --> 01:12:46,239 doing a lot of additional um analytical 842 01:12:46,239 --> 01:12:48,080 requests in terms of spike recoveries 843 01:12:48,080 --> 01:12:50,239 and everything. And so I say that all to 844 01:12:50,239 --> 01:12:52,000 say we have not published it publicly 845 01:12:52,000 --> 01:12:53,600 because we're we've been really busy 846 01:12:53,600 --> 01:12:55,840 trying to verify this new data set. 847 01:12:55,840 --> 01:12:57,360 We're close to doing that. We're close 848 01:12:57,360 --> 01:12:58,960 to wrapping that up and we hope that by 849 01:12:58,960 --> 01:13:01,040 the end of the summer we will load all 850 01:13:01,040 --> 01:13:04,239 of our data into um water quality portal 851 01:13:04,239 --> 01:13:05,600 so that it will be available to 852 01:13:05,600 --> 01:13:07,199 everyone. [snorts] 853 01:13:07,199 --> 01:13:09,440 >> Fantastic. And then um you already 854 01:13:09,440 --> 01:13:11,520 touched on uh this I think but I just 855 01:13:11,520 --> 01:13:12,640 wanted to double check because I'm not 856 01:13:12,640 --> 01:13:14,880 as used to thinking about dissolved 857 01:13:14,880 --> 01:13:17,280 nutrient species but um this is 858 01:13:17,280 --> 01:13:20,000 measuring just like dissolved uh nitrate 859 01:13:20,000 --> 01:13:22,239 nitrite and ammonia and it does not 860 01:13:22,239 --> 01:13:24,640 count things that are like currently 861 01:13:24,640 --> 01:13:27,840 locked up inside biomolelecules. Uh 862 01:13:27,840 --> 01:13:28,400 correct. 863 01:13:28,400 --> 01:13:30,880 >> This would so this total dissolved 864 01:13:30,880 --> 01:13:33,520 nitrogen uh metric does include organic 865 01:13:33,520 --> 01:13:35,920 and inorganic forms of phosphor or sorry 866 01:13:35,920 --> 01:13:37,520 nitrogen 867 01:13:37,520 --> 01:13:38,880 >> and phosphorus. 868 01:13:38,880 --> 01:13:41,199 >> Uh we do have phosphorus. Yes. Two also. 869 01:13:41,199 --> 01:13:41,520 Okay. 870 01:13:41,520 --> 01:13:42,000 >> Mhm. 871 01:13:42,000 --> 01:13:42,320 >> Yeah. 872 01:13:42,320 --> 01:13:44,480 >> Wonderful. Thank you. 873 01:13:44,480 --> 01:13:46,400 >> Yeah. Um and the dissolved fraction is 874 01:13:46,400 --> 01:13:50,390 045 microns. 875 01:13:50,400 --> 01:13:51,920 045. Yeah. 876 01:13:51,920 --> 01:13:55,360 >> Gary, you had your hand raised. 877 01:13:55,360 --> 01:13:58,480 >> Yeah. Uh just Scott's question about 878 01:13:58,480 --> 01:14:02,640 picking a time of the year that is uh 879 01:14:02,640 --> 01:14:05,840 most uh instructive in terms of the uh 880 01:14:05,840 --> 01:14:09,120 nitrogen value. I think uh couple 881 01:14:09,120 --> 01:14:12,880 cautions here. [snorts] Um one is 882 01:14:12,880 --> 01:14:15,120 because of the problems of measuring 883 01:14:15,120 --> 01:14:18,960 nitrogen in the hypersailing water. um 884 01:14:18,960 --> 01:14:20,960 we're talking about total dissolved 885 01:14:20,960 --> 01:14:24,400 nitrogen and biologically the most 886 01:14:24,400 --> 01:14:27,920 important is the inorganic nitrogen 887 01:14:27,920 --> 01:14:33,199 and um that those measurements are uh 888 01:14:33,199 --> 01:14:38,400 not as uh good because of the uh 889 01:14:38,400 --> 01:14:41,360 oftentimes they come in beyond detect 890 01:14:41,360 --> 01:14:43,600 they can't be detected they're below the 891 01:14:43,600 --> 01:14:47,440 uh criteria for detection and so total 892 01:14:47,440 --> 01:14:49,679 dissolve nitrogen is being used because 893 01:14:49,679 --> 01:14:53,280 that is easil more easily measured. 894 01:14:53,280 --> 01:14:56,640 Second of all, the problem that you face 895 01:14:56,640 --> 01:14:59,600 um with a time of the year is that the 896 01:14:59,600 --> 01:15:02,960 phytolanton are very productive in the 897 01:15:02,960 --> 01:15:06,159 wintertime often before uh without 898 01:15:06,159 --> 01:15:09,600 grazing by the the shri the shrimp. And 899 01:15:09,600 --> 01:15:12,560 as a result, that's critical and that 900 01:15:12,560 --> 01:15:14,560 helps to go into how much you're going 901 01:15:14,560 --> 01:15:17,360 to have into the spring and early summer 902 01:15:17,360 --> 01:15:20,320 as the shrimp population starts to grow. 903 01:15:20,320 --> 01:15:22,719 But that also you need to know the 904 01:15:22,719 --> 01:15:25,760 nitrogen at other months um because 905 01:15:25,760 --> 01:15:28,400 that's when the uh phytolankton is 906 01:15:28,400 --> 01:15:31,440 recovering from being fed upon. So 907 01:15:31,440 --> 01:15:33,840 trying to pick a particular time that's 908 01:15:33,840 --> 01:15:36,400 most important I think is much more 909 01:15:36,400 --> 01:15:43,189 difficult than the salinity question. 910 01:15:43,199 --> 01:15:46,080 I'll just add that um in the winter 911 01:15:46,080 --> 01:15:47,840 months there there's a lot of 912 01:15:47,840 --> 01:15:50,000 chlorophyll but when we measure carbon 913 01:15:50,000 --> 01:15:53,520 assimilation it's very low. So um 914 01:15:53,520 --> 01:15:56,480 photosynthesis like most biochemistry 915 01:15:56,480 --> 01:16:00,159 works very slowly when it's cold. So um 916 01:16:00,159 --> 01:16:02,320 that we shouldn't equate presence of 917 01:16:02,320 --> 01:16:08,310 chlorophyll with actual metabolism. 918 01:16:08,320 --> 01:16:10,239 Let me just point out the metabolism 919 01:16:10,239 --> 01:16:13,120 isn't the necessarily the key. It's the 920 01:16:13,120 --> 01:16:16,080 population that is the food resource for 921 01:16:16,080 --> 01:16:19,199 the grazer. So, you know, 922 01:16:19,199 --> 01:16:28,229 >> that's absolutely. Yeah, I agree. 923 01:16:28,239 --> 01:16:32,470 » Other questions? 924 01:16:32,480 --> 01:16:35,120 Okay. Well, thank thank you both um for 925 01:16:35,120 --> 01:16:38,400 these sort of different perspectives on 926 01:16:38,400 --> 01:16:40,320 the same 927 01:16:40,320 --> 01:16:43,360 uh the same issue that that we're 928 01:16:43,360 --> 01:16:45,040 looking at. This is really interesting 929 01:16:45,040 --> 01:16:46,960 but a helpful conversation. Come back to 930 01:16:46,960 --> 01:16:50,320 the salinity advisory committee meeting for more at the end of 931 01:16:50,320 --> 01:16:52,960 the month. Um Ben made the joke that 932 01:16:52,960 --> 01:16:54,320 we're considering calling it the 933 01:16:54,320 --> 01:16:56,480 salinity and nutrient advisory committee 934 01:16:56,480 --> 01:16:59,990 which is snack 935 01:17:00,000 --> 01:17:01,199 » um for snacks. 936 01:17:01,199 --> 01:17:02,719 >> Yeah. 937 01:17:02,719 --> 01:17:10,640 Thank you so much everyone. Um I know that for our um visitors here 938 01:17:10,640 --> 01:17:12,800 today the specific content might not 939 01:17:12,800 --> 01:17:15,520 have been exactly relevant to to the 940 01:17:15,520 --> 01:17:16,719 problems you're working on, but are 941 01:17:16,719 --> 01:17:18,719 there any questions about the tech team 942 01:17:18,719 --> 01:17:21,040 in general or about the lake um more 943 01:17:21,040 --> 01:17:23,199 broadly that anyone in this room might 944 01:17:23,199 --> 01:17:29,350 speak to? 945 01:17:29,360 --> 01:17:32,800 So, one thing that that so you guys 946 01:17:32,800 --> 01:17:34,880 please this would be an opportunity to 947 01:17:34,880 --> 01:17:38,480 speak with people. Um, and I believe the 948 01:17:38,480 --> 01:17:39,840 plan is still to stay in here and 949 01:17:39,840 --> 01:17:41,600 continue some conversations, but I'm not 950 01:17:41,600 --> 01:17:44,800 sure Angela, but um, so one of the 951 01:17:44,800 --> 01:17:46,000 things that I wanted everyone to 952 01:17:46,000 --> 01:17:47,440 understand is this is a public meeting 953 01:17:47,440 --> 01:17:49,840 and this is how discussions and 954 01:17:49,840 --> 01:17:51,520 management of this resource sort of 955 01:17:51,520 --> 01:17:54,320 evolve. This is one of them. So, just 956 01:17:54,320 --> 01:17:56,400 consider that. Um, and then I'd also 957 01:17:56,400 --> 01:17:59,199 like to point out Bonnie over here who's 958 01:17:59,199 --> 01:18:01,600 done a lot of work. You you can tell the 959 01:18:01,600 --> 01:18:04,159 people who are actively engaged in the 960 01:18:04,159 --> 01:18:07,280 science here. Um, and so she's at a 961 01:18:07,280 --> 01:18:09,679 university in town. Gary's at a 962 01:18:09,679 --> 01:18:12,320 university someplace else. And it's also 963 01:18:12,320 --> 01:18:14,480 just really I think really important to 964 01:18:14,480 --> 01:18:16,560 understand the number of different 965 01:18:16,560 --> 01:18:19,280 entities that that share a common 966 01:18:19,280 --> 01:18:22,239 interest and and and how science and 967 01:18:22,239 --> 01:18:25,920 management advances in this system. Um, 968 01:18:25,920 --> 01:18:27,920 so 969 01:18:27,920 --> 01:18:30,960 anyway, have at it please if if you have 970 01:18:30,960 --> 01:18:34,239 some thoughts or or or anything about 971 01:18:34,239 --> 01:18:36,800 this system or or the governance you're 972 01:18:36,800 --> 01:18:45,270 kind of observing. 973 01:18:45,280 --> 01:18:47,360 » Okay, great. Well, no pressure right 974 01:18:47,360 --> 01:18:49,120 now, but it but you know, as the meeting 975 01:18:49,120 --> 01:18:51,199 wraps up, you can stay and and chat with 976 01:18:51,199 --> 01:18:54,159 any individuals that you you'd like to. 977 01:18:54,159 --> 01:18:56,960 Um and I also and I also neglected um at 978 01:18:56,960 --> 01:18:57,920 the beginning of the meeting to 979 01:18:57,920 --> 01:18:59,520 acknowledge that we have a lot of folks 980 01:18:59,520 --> 01:19:02,960 online um who are listening in and and 981 01:19:02,960 --> 01:19:07,280 can participate.
