This is a classic case of you can't have it all. we ( not me ) think we can have unlimited population but we don't like the side effects, people need food, agriculture requires water so something is bound to change.
The farmers in the Klamath basin have water rights going back to the 1800's, if there was a problem something should have been done before a community was build over the last 100 years dependent on ag. I'm a half breed so I can feel for the natives, but things change and they have to adjust to these changes, they can get their fish at Skipper's like I do some years, they aren't going to starve without it.
The real story behind the Klamath fight is the ESA, when the fish freaks decided the suckers needed more water in the lakes for them to survive that reduced stream flows , then the indians down stream threw a fit so the farmers were the least powerful therefore most expendable. most years with proper managment there can be enough water to keep everyone from killing each other, but tensions run high.
In my opinion everyone has to give a little, the suckers may have to live in a smaller swamp, the indians might not always have great fishing and the farmers will have years they fallow some ground. for anyone to be happy means someone is getting screwed, this is the unfortunate truth of the matter and I'm glad I have no part of it.
