Don; They want to remove any roadblocks to the raising of Shasta Dam -- and just 6' or 18.5'. They want to raise it the full 200' (can you imagine how much of the Pit, McCloud and Upper Sacramento Rivers we'd lose?).
Their goal is to receive their full water allotment -- so they can turn around and sell it to urban areas at an obscene profit (after buying it at heavily subsidized rates).
I covered this in the Trout Underground here:
