Not true...   100 years ago or so, heavy rain caused the Colorado to overflow.  I think it did breach some flood control dikes, but there were no dams on the Colorado at that time.  It was NOT a man made effect.

Sorry Bill, it sure was a Man made effect. Don't want to say it was a screw up because it's supplied water for a very fertile valley for growing crops in the Imperial Valley which has had past holdings as Lettuce Capital of the world, and Carrot capital of the world but still a very fertile valley for production of winter vegetables. Yuma now claims the title for Winter Lettuce capital of the world along with most vegetables as broccoli, cauliflower, romaine, spinach and cabbage.
