California' reservoirs are now all maxed, and there's the re-formed Lake Tulare that's already the size of the Bay, and will double in size in a month.
So Cal ought to be able to re-route a lot of that excess water...for a couple of years.
I have a very good friend who owns a lot of central Cal farm land and his opinion is the state would rather flex draconian control than build reasonable systems to better capture and store water.
Lake Mead and Lake Powel are surging up big time, from historic lows. But always an open question how things will turn in the future. Only seems sensible to employ both conservation and better water retention efforts.
