How about we build a dam or two. Just a thought.
The surface evaporation and the lack of snow pack up north are turning them into mud pits.
Not to mention the need to dredge just to keep the generators turning.
The Colorado reached the Sea of Cortez this year. First time in about fifty years.

Hetch Hetchy has worked flawlessly for how long? That you cite a pair of dams with totally different geology than the Sierra Nevada shows how little you know of what can be done with dams. Some work, some don't. Whether or not they work is sit specific.
Damming the Trinity totally changed the Sacramento fishery from perch to salmonids simply with the injection of colder water. I'd call that a good deal. Using that same water to run out the Klamath in summer causes the fish to come in early, finding spawning habitat that is likely to cause a die-off. So there you have an example of a dam that can be used well or badly.
