#GreatSaltLake solution
Cap reservoir storage
Instead of filling every reservoir to capacity, cap reservoirs at 60,70, 80, 90% depending on actual needs of individual reservoirs.
This would cut down on evaporation losses, allow flows to return to the GSL and make water conservation meaningful.

Truth is like a lion, set it free and it will defend itself
Water conservation increases upstream retention by reducing inflows to #GreatSaltLake.

3 years in and I am seeing some public perception change🥳
Assumptions about conservation helping GSL are being replaced by evidence of management malpractice. If we can change the false narrative we can bring positive change to inflows. Then we can help mother nature rebuild elevation.

Derivative Junk Science.
If the first layer is already pseudoscience, and subsequent layers build on it, some critics call this “meta-pseudoscience” or “derivative junk science.

178 years is GSL's recorded history, a tiny fraction of its life. Yet, it is used as a baseline for projecting its health status.

as far as I can tell nobody reads me here, so I use this place to put together thoughts. I am going through the M&I document put out by UTDNR. I realize they are trying to retrofit decades worth of supply side water management into the new Great Salt Lake narrative. but it doesn't fit.

It appears to me that there really has not been a solid Great Salt Lake study. The USU study was on saline lakes in general, but each lake has its own nuances. BYU study took generalized information from Colorado river and else ware and applied it to the GSL. Nothing strictly GSL hydrology.

A list of reservoirs in the GSL basin.
Looking at this list exemplifies how problematic past #GreatSaltLake studies have been in omitting their retention and evaporation as a large portion of flows missing from GSL.
It has let policy make decisions on half of the information needed.

Understanding return to flow.
When you take a shower, press the plug down and allow the water to build up, notice how much water accumulates. when you pull the plug that water drains to the GSL after sanitation.
That is return to flow.

There are 3 ways it can playout.
Cap reservoirs and see positive change over time.
Weather steps in and delivers more precipitation than reservoirs can retain.
Continue water conservation as is, which depletes return flows and watch the lake diminish over time.

3 years ago, UTDNR claimed "GSL could dry up in 5 years", I knew they were full of shit. That started me on my journey of investigating everything GSL related.
UTDNR claimed water conservation, especially agriculture could "save" the lake, instead, that turned out to be a net negative.

The berm was raised.
The metric was not met - acre feet to the lake.
The lowering of salinity in the south arm is not guaranteed.
The rise of salinity to the north arm is the most likely outcome.

Going forward if the Utah media is mentioning the GSL but not talking about excessive reservoir storage and acre-feet to the lake, just know it is click bait. All the rest is theatrics.

Sooner or later policy makers are going to have to meet me at capping reservoir storage. Otherwise, status quo will continue, and the lake will slowly decline more. Let's hope they come to their senses sooner than later. If they don't it could get really costly to taxpayers and the GSL ecosystem.

Diversion ≠ Depletion
Imagine you scoop water from a stream into a bucket.
If you pour some of it on a plant, that portion is gone.
But if you dump the rest back into the stream, that portion keeps flowing.
That’s the difference
