We can add water management to the list of subjects in which Scott is
expert. Where do you propose storing the snow melt when it arrives?
We obviously need more and larger reservoirs or get off the snow melt dependency.
But neither is happening.
Snow melt is where California's water comes from. More reservoirs?
Pretty much every river in CA is dammed for flood control already.
It's much easier to "add capacity" by reducing consumption.
Meanwhile enough water has just run down the LA (concrete) River
into the Pacific to supply all of LAs water needs for a year.
Where would you store all that water?
“When you look at the Los Angeles River being between 50% and 70%
full during a storm, you realize that more water is running down the
river into the ocean than what Los Angeles would use in close to a
year,” said Mark Gold, associate vice chancellor for environment and
sustainability at UCLA. “What a waste of water supply.”

That's a need that is currently met by pumping water from far north.
Those pumps consume 1/3 of Ca. electricity. We spend more money on
keeping homeless methheads high than on increasing Ca. water
infrastructure.
I'm pretty sure that last claim is incorrect.
A little...that's peak demand percentage which is an issue when rolling blackouts
are required. Those pumps really can't be just shutdown.
That wasn't the incorrect side of the equation.
But the total consumption is still around 1/5, by far the largest consumer of electricity.
If you want to use the Los Angeles River, here's Mr Sustainability, Mark
Gold:
https://newsroom.ucla.edu/releases/ucla-study-los-angeles-independence-from-imported-water
“Los Angeles needs to reduce local water demand while also transforming
its water supply infrastructure to maximize recycled water, groundwater
supply and stormwater capture.”
That proposal suggests rather than a megaproject like a reservoir, "tens
of thousands to hundreds of thousands of treatment and infiltration
devices," ie bioretention ponds.
If you're bemoaning water "lost," there's hope:
https://www.reuters.com/business/environment/california-cover-canal-with-solar-panels-experiment-fight-drought-climate-change-2022-08-25/
"California is about to launch an experiment to cover aqueducts with
solar panels, a plan that if scaled up might save billions of gallons of otherwise evaporated water while powering millions of homes."
