It percolates into the groundwater, even if it drains through a drainage canal. None of what you quoted refers to the amount of water that is actually consumed in the crop and unused in the future.
Actually most of it evaporates when it is 100 degrees and sunny all the time, with low humidity. The ground is clay, which is why it is good for rice and not other plants, partly because it DOES NOT soak up the water.

Actually, there are a lot of water saving techniques used in my area that cut way down on the water consumption (some up to 2/3 total gallons). I don't believe that you cant grow rice in CA, you just have to be smarter about it.
Yes, but the people in the state won't force the growers to change because their focus is on shaming their neighbors for getting a car wash.

Water percolates through any soil. It may be slower than sandy loam, but it goes into the soil. MOST is not a correct term. Some water evaporates, because with a permanent flood, all the surface water is exposed. They could furrow irrigate rice, which saves between 2/3-75% on your water consumption. The problem is that the farmer gets nothing in return for using this practice. It is a riskier way of rice farming. CA-Ag dept should look into this type of program. I know when the drought was at peak, farmers were paid to simply not grow rice as a way to combat consumption.

What I don't understand is the process they use for desal.
On my submarine, we used the superheated water from the nuke power plant coolant system to boil seawater and then condense the steam for freshwater.
These desal plants use high pressure (high energy consumed) pumps to push saltwater through filters to get the salt out.
Why couldn't the 2 large commercial nuclear power plants on California's coast be retrofitted so that their secondary coolant (non-radioactive) can use the same process the US Navy has proven over the last 70 years?
I think it's a problem of scale and efficiency.
Reverse osmosis is simply more efficient than boiling water. IF you have excess energy (as on a sub), it still makes sense to just boil water. Power plants are already very efficient. If they had enough "waste" energy to boil water for desal, why wouldn't they use it to generate more power instead? They probably do.

OK, but if the water percolates 3x slower through the clay (I made that up), then it allows for the water surface to be exposed a lot longer for more evaporation. I just don't see it as an efficient use of water in that particular area of the country.
I don't disagree about cows and alfalfa being big parts of the problem too.

When people say this, I envision some guy sitting in all camo with a shotgun and a bible who is about to field dress a deer. California undoubtedly has its issues, but saying it sucks is completely inaccurate. It's probably the most diverse state as far as scenery and climate go. Big Sur is awesome. San Diego is awesome. LA is meh. San Fran is awesome but$$$ and, NorCal is some of the most beautiful country i've ever seen.
When people say California sucks they're talking about the government corruption and hypocrisy of the vocal left.

I assure you there is plenty of energy left to boil seawater efficiently especially during times where demand for electricity is not at its peak. Using a balancing scale that maximizes the heat generated from a nuclear plant to produce either electricity or freshwater

I know this is a stupid question.... but... that big white line in Lake Mead showing the drop in the water level... that not from California using water... that's from Colorado not putting enough water into the reservoir, right? As in.. it's not raining/snowing enough to keep the reservoir full. Which, in turn, causes issues with the amount of water Cali pulls from the river, right?

California is probably the most diverse State as far as geography goes. It's a microcosm of the USA.
I think when people criticize it, they're talking about the elitists who push for/pass legislation while living in ivory towers and not really having to deal with the real world, like the average American does.
Coastal California is a very unique place, in several ways.

Anyone been to Yellowstone in the spring? It's jaw dropping insane what melting snow looks like coming down the mountains. Crazy how those little trickles eventually turn into raging water as you follow it down

Former Alaska Gov. Wally Hickel proposed a water pipeline from AK to California. Some places here in Southeast get over 200" of precip.

To be sustainable, you not only have to support the people and critters but maintain an ecological balance and keep from depleting natural resources. You're arguing the wrong concept of the word.
My point is that it is sustainable if they're not careless. Their issues are not irreversible.

They have a huge aqueduct that brings water south to reservoirs from the Sierra Nevadas. Been in place for 70 years. Problem is, sometimes the Sierras get 400+ inches of snow, and other years they get 150 inches. They've had a number of consecutive years (prior to this past winter) that were in that 150 inch range.
This also steals water from the high desert areas up near Lake Mono, which absolutely destroyed the Upper Owens river (formerly a great resource for trout fishing and duck hunting).

That's what makes the Mississippi River, isn't it? Melting snow?
Heck, it floods every year, they should divert some of it to California with a long pipeline
