Groundwater and aquifers still depleted.
The southern end of the central valley (San Joaquin region, whole central valley is outlined in red) is particularly hard-hit by groundwater depletion. Some of that storage does not come back, because the ground compacts after the groundwater is withdrawn.
If only we built reservoirs to keep the water for the drought years it would be great news.
Could use some large scale geo-engineering. Pity that we don't have a radiation-free way of blowing a gigantic hole into the ground that can store a few trillion litres.

California has already invested a lot into reservoirs. In fact, as a pilot, I recall noticing that nearly all lakes in California are actually man-made reservoirs. I doubt there is much room left for economically building more; all the easy ones have been taken, and more. Surely the cost benefit of just investing a lot into desalination must be getting close.
I haven't heard of any new desalination projects making headway since. The cost-benefit analysis may favor it, but I'm not sure the politics do. Of course, those politics will probably change in 10-15 years in our next big drought cycle, and then we'll really wish we'd gone forward with more desalination.

In 2020 federal memo and regulatory changes under Trump's first administration to send more water from Northern California to Central Valley agriculture via federal projects were ignored by the governor of california, and instead of allowing the water to flow into southern california, his office sued over those Trump-era water rules, arguing they violated environmental protections for endangered fish.... had he done…
All urban use is 11% of California water. SB79 has nothing to do with the drought. Gavin Newsom ran on building housing, and SB79 is him fulfilling his mandate from voters, "local resistance by residents" is why California has some of the most expensive housing in the world.
there would be no drought if the 2020 Federal regulations were followed. the only reason there's no drought today is because the federal government stepped in and finally opened up the water lines in the North coming south.
keep in mind there used to be a big freshwater lake (Tulare Lake) in the middle of California for at least ten thousand years.....

Desalination must be insanely expensive; I’m always shocked it wasn’t done decades ago. Considering California always seems to have power and water issues, I’d think combining these things would make a lot of sense. Some of these exist and there seems to be a fair bit of research in the area. I have to image at some point that will be the direction California would need to go. Of course, if they are all-in on solar a…
It isn't. Mostly there are environmental concerns.
Previous CA resident anecdata, I remember droughts being a normal part of life in central CA 1990-early 2000s. Don't run sprinklers during certain hours, odd/even watering, "the water bill" exclaimations, etc. Like another commentor mentioned I don't anticipate this will last, but it's nice to see the "official" state change even if for a bit.
I recall rather absurd demands such as telling restaurants not to offer water (as if a glass of water makes any difference) and telling residents to skip showers.

Got any sources for that?

2. The water management plan has nothing to do with where water flows to fight fires.
3. A legal fight in 2020 is not caused by a bill that was passed in 2025.
> there would be no drought in 2020
That’s not how droughts work. A drought is a lack of rainfall. Moving water can reduce the problems caused by a drought, but it cannot prevent a drought.
I've lived in California my whole life (and the same town for most of that). This was the most rain I can remember in decades and the most "destruction" I've seen caused by it. Between the ground being saturated and wind before/after/during the storms there were plenty of downed trees. We were also down to running sprinklers once a week (lawns are silly), but have had them off entirely for a bit now.
The statewide rain totals for the 2025-2026 water year so far rank 6th out of the years of the 21st century, so aren't that remarkable in context. Do you live in a place that got slapped with a peculiarly high rainfall?
