How then, genius, do you explain the great flood of 1860?
That happened before the network of dams and reservoirs were built to even out the dry years.
Which your 'Bugs and Bunny' buddies demolished a couple of decades ago.
Incidentally, the Ocean does not need the water to keep the fish alive. But the valley streams and rivers sure do; that's what the function of the dozens of dams no longer there was, to keep the streams flowing. Most of the junk fish and worms and reptiles and frogs etc., in the valley have died.
And do you even have a clue about just how many damns and reservoirs have been "demolished"? I think you don't.
Do you know if CA has increased, or decreased reservoir capacity? Probably not.
