The lake responded the same way during the drought of 1975-6. Very high cyanobacteria blooms. All from legacy nutrients and high temps.
Alicia Cortes

Yes, but the lake didn't have the same conditions. As an example: (A) In 1975-6 the lake had a mean dissolved oxygen concentration ~8 mg/L and orthophosphate ~0.03 mg/L; (B) In 2020-21 the lake mean dissolved oxygen concentration ~7 mg/L and orthophosphate ~0.15 mg/L. These conditions are driven both by the cumulative input from the stream loading plus the lake suffering from extreme events over the years

One of the priorate's should be to bring the lake management to the local governments. Is that in the mix?
Jim Steele
01:09:47
You need bench marks to determine success. So the BRC should determine what those should be.
Jim Steele
01:12:14
That's a technical questions rather than a political one. So maybe there should statements in both categories.

Recovery of hitch populations is another important goal.
Jim Steele
01:15:33
The political goal is to have lake conditions where it is safe and usable for recreation and visitor use.
Jim Steele
01:16:24
The technical goals are to have a management plan with measurable metrics that define progress.

Replace "have" with "implement?"

I know the focus is on the lake but what we do in the watershed from the policy side should be in the mix.

Sorry, I need to hope off the line. Thank you for the stimulating conversation.

"Develop solutions" or identify solutions and benchmarks? I don't think the committee is the funder but they can guide direction.
Jim Steele
01:47:22
Improve natural shoreline area, increase wetland numbers and functions. We're at >85% loss right now.

Management Questions for Nutrient ResearchA. Is there a water quality problem?B. Are nutrients contributing to the water quality problem?C. Can nutrient management help address or ameliorate the problem?D. Are particular hydrologic, biological, meteorological, or biogeochemical conditions needed for nutrient management to be effective?E. How may anticipated future Delta conditions affect the nutrient-related problem?F. What nutrient management measures are needed to protect beneficial uses now and in the future?

At a higher level are we talking about a healthy and sustainable,resilient lake capable of withstanding extreme climate events.

Jim's statement sounds robust
