Of course by the same token the water is “state-induced” too, as all the dams were build by the government.
There are considerable small private dams in California, however they have been under attack from the state and the state has been refusing to build or upgrade public dams for decades, while there are serious threats to existing public dams in the name of "environmentalism".
The only real efforts to "manage" water in CA is how will we transfer northern water to the south, and how much will be transferred?
There hasn't been STORAGE conservation efforts for decades.
Finally, California's large valley areas are rain shadow areas that fortunately have two major rivers that run through them, so "drought" is the standard pattern for California, but hurts only when you improperly manage your water.
