Wow if that is not intentional misinterpretation I don't know what is. The water reduction was not caused by congress or by any senator. It was instituted by the U.S. Fish and Wildlife Service, which is neither crazy or an environmental extremist organization, but is a non partisan independent federal government agency.
I'm not saying that I agree with their decisions (which BTW has stood despite several court challenges), but if name-calling and assigning of blame is going to be posted, at least assign it to the correct party.
It might be worth reviewing some of the documentation posted on the subject by the U.S. Fish and Wildlife Service to see what their justification for their current stance and further plans are for this particular issue:

I agree that the action seems excessive and have to wonder whether a better solution might not have been viable. I have to imagine that some kind of engineering solution is possible. I would be interested in reading the actual report from the U.S. Fish and Wildlife Service explaining why they have taken the decision they have.
