Delta Blues is a documentary about the environmental crash of one of the most important ecosystems in the United States - and one of the least known. The California Delta is the center of disputes over fish, water supplies for over 60 percent of the state and the future of farming in the Central Valley. Add in the fact that California is broke, the continued lack of political will to solve the crisis and the possible extinction of two species of fish, and a dramatic tale begins to unfold.
