Expand Los Vaqueros Reservoir
Temperance Flat Dam
Sites Reservoir
Ah Pah Dam
Auburn Dam
Raising Shasta dam
Ah Pah and Auburn were never viable projects way back when and are not today, except as a joke. They are in the same category with building a dam in the Grand Canyon.
20 years ago I read the book Cadillac Desert that covered those type projects. If you have never read that book, you should.
As for Los Vaqueros, there is no enviro opposition to that project, its a funding problem. I noticed that House members George Miller and Jim Costa were trying to get Congress to fund it. And mentioning George Miller, Cadillac Desert contained the story of how the Miller family came to have their ag empire. Very interesting story.
The Temperance Flat dam is going forward. The voters approved the money last Nov. It took a long time to get the money because previously they scoffed at it but as the problem became worse, minds changed.
Sites Reservoir got money in the same bond issue as Temperance Flat. Enviros won't stop that because there is no river dam involved. Its only an off stream storage area. Other monies will be needed.
Raising the Shasta Dam also got some money from the same bond issue, but they will need a lot more from Congress. There is some enviro opposition and tribal opposition, but if Congress appropriates the money, it will go.
But Shasta is a lot of money for not much more capacity. None of these are large capacity.
