Doc, while it is easy and fun to blame Feinsten and Trump for what will happen to CA water, the problem is a lot closer to home. Too many people, and most located in virtual deserts. For options, let's just say that they decide to leave all the water in NorCal and use it for fish and people Norte of the Tehachapi's.

Were do the fruits and nuts south of there get water? Whose rivers get dried up? Already dried up the Colorado.

It won't be too long before the political power of the folks who want water tap the Big C. Because they also want the power, they'll take it at Bonneville, after generating the power there. Some really bit aqueducts send it down to (probably) the upper Sacramento where it then enters the distribution system.

While in college I heard a proposal from a CA legislator to dam the Carquinez Straits (upper end of SF Bay) to capture all of the Central Valley freshwater for export south. And this was a really long time ago.
