The Great Salt Lake's unofficial watchdog, blending hydrology with weather watch, advocating for natural precipitation and better water management over conservation myths.
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.

I did a review of the information on twitter.

2025 GSL lost 1.5' year over year.
Still a gain of 2.5' over 2022' low elevation of 4188.5'
Average snowpack, below average summer precipitation ending at 85% of median.

The story made a big deal about soil moisture, so I checked.
considering the dry summer, it looks pretty damn good.

Kind of silly.
KSL did a story on reservoirs. We are at the end of the water year. We had a dry summer. Jordanelle is still almost 80% full, the rest as you can see are above 60%.
Every year we get snow. The reservoirs will replenish. Water is not scarce, it is mismanaged.

Governor cox is getting more bad advice from the politician he installed to lead the DNR. Making an unnecessary drought decree. A couple of counties, okay. Ferry is an alarmist, remember the "nuclear time bomb", then the lake grew. He can't be trusted. Another way to get a hold of tax funds?

#GreatSaltLake dust monitoring is complicated
Even more complicated when UTDNR is contaminating samples by burning phragmite, like today.
Ogden pollution is elevated today in the path of the smoke column

In the 2023 water year, Human consumption was only 5% of water yield instead of 23.3%.
Total yield 35,700,000 acre-ft.
Human consumption (HC) 1,786,539 acre-ft.
Agriculture depleted 75.8% of the human consumption, only 4% of yield.

Rather than the GSL contaminating urban areas, it appears urban areas emit more pollution.

Up 1.4' on the season
Up 5' above November 2022's low elevation.
Instead of receding the GSL has been gaining elevation for 2.5 years thanks to nature.
