What an interesting read. I had no idea that the Central Valley had been so full of water, nor that it had been drained so early. After reading the article I found this "conceptual" map which illustrates approximately what it may have looked like circa 1851: https://geocurrents.info/wp-content/uploads/2012/06/Californ...
The cynic in me thinks this is what our future generations are doomed to - reading articles of what the world was like before massive global climate change and thinking, "wow, I wonder what that world was like, I can't imagine it," and simultaneously, "what were those people thinking, how could they care so little for the environment?"
