“Well it used to be back when.”
CA has had years when nearly the entire big valley was flooded.
1986 was the last big one.
But as recently as 2017 we’ve had more than we could use.
Those years are exceptional.
Most years we get just barely enough, and many years not quite enough.
We are perpetual drought and flood. Usually 3-5 years of drought followed by WAY too much.
Haven’t been there since 1980-81
