They don't have water to spare for that.

it would probably take more energy to pump it up than it would make coming down.
Doesn’t have to be fresh water
Say you get 35% loss, that’s still a lot of potential energy you’d be able to unlock. You’re big trouble is that it’s California and they can **** up anything.

Power with Control
But with salt water your equipment suffers

True, but salt water introduces all kinds of maintenance issues. Corrosion from salt, barnacles, etc... Might raise the cost to beyond acceptable.
Pumped Storage Hydropower
WHAT IS PUMPED STORAGE HYDROPOWER?
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge). PSH acts similarly to a giant battery, because it can store power and then release it when needed. The Department of Energy's "Pumped Storage Hydropower" video explains how pumped storage works.The first known use cases of PSH were found in Italy and Switzerland in the 1890s, and PSH was first used in the United States in 1930. Now, PSH facilities can be found all around the world! According to the 2021 edition of the Hydropower Market Report, PSH currently accounts for 93% of all utility-scale energy storage in the United States. America currently has 43 PSH plants and has the potential to add enough new PSH plants to more than double its current PSH capacity.

I read an idea about energy storage some time back, and I haven't seen much of it - since.
One of the challenges of a nuclear power plant - I imagine, just about any power plant - is matching demand to production. Now I don't get everything about producing power, but I imagine that while you don't want to produce LESS electricity than needed, if you produce more, you're just going to waste it as heat. But if you use that heat to STORE energy - and I imagine many of them do - you can just run at full speed all the time.
The idea for a nuke plant was to use the extra energy to make hydrogen. It's not as though it's complex, and it's clean. Run at full throttle, use the "extra" electricity to create hydrogen, and just store it and sell it or use it. Unlike say, a battery, it's not going to lose anything.

were talking storage, not generation

Losses with hydropower storage are acceptable, because the goal is to offset the generation of power to a time where it's needed. Use "green" power sources to lift the water, then use the water to generate power when other sources cannot or during higher-than-normal peaks.
If you want to talk losses, a typical solar panel is less than 20% effective at creating electricity from solar.

When it's at the top of the hill, yes. Stored potential energy.
the water is the ' stored ' power ?
One drawback I can see here is that hydrogen sometimes goes all Hindenburgy
Face It Newsom, You'll Never Be DeSantis
During an interview, Newsom said he worries about former President Trump but worries more about both Fox News host Tucker Carlson and DeSantis.
"I worry about Trump. I worry about Trumpism… I worry more about Tucker Carlson. I worry about Ron DeSantis,"Newsom said while speaking at the Texas Tribune Festival in Austin.
DeSantis previously threatened the Special Olympics that he would fine them $27 million if they refused to lift their Covid-19 vaccine mandate, which they eventually gave in and lifted it.
Newsom called DeSantis a “bully,” however the Florida governor was the only person to stand up and fight for athletes so that they can compete.
Newsom Seeks to Delete Law That Makes it a Crime to Kill a Baby After It's Born
Introduced by Assembly member Buffy Wicks, the proposed bill would do away with its current infanticide law which makes it a crime to kill a baby that was born within a year.
If Newsom goes ahead and signs into a law, the bill would erase the requirement for a county coroner to hold inquests to investigate perinatal deaths “related to or following known or suspected self-induced or criminal abortion.”
It would also bill “delete the requirement” for a coroner to handle “an unattended fetal death” as a “death without medical attendance.”
Doing away with this law would also protect those responsible if a baby was left to die after a failed abortion, meaning it could effectively legalize infanticide up to twenty-eight days after the baby is born for any reason.
Last week Newsom launched a series of ads blasting Republican states who have placed restrictions on abortions with several of them taking aim at the Bible.
Gavin Newsom: ‘I Worry About Ron DeSantis’
He threaten this Special Olympics with $27 million in fines. Who does that?” he said, failing to explain that the DeSantis administration did so to stand up against the vaccine mandate requirement, which would have prevented many athletes from participating. What is more, some athletes attempted to comply with the mandate so they could participate, and the results were dire.
“This June with the Special Olympics, they imposed on the athletes a COVID vaccine mandate. … If you did not submit and you did not get the COVID vax, you would be denied the ability to compete in the Special Olympics,” DeSantis said during a press conference in June, explaining that some got the vaccine “even against their judgment”:
