The Columbia River and Snake River dams and reservoirs provide substantial benefits in the Northwest through their operation for hydropower, flood control, irrigation, navigation, and fish and wildlife. The listing of certain Snake River salmon stocks as endangered and threatened, under provisions of the Endangered Species Act, has surfaced major public policy issues. Protection and enhancement of these salmon stocks has resulted in proposals to significantly modify the operation of the reservoir projects. Implementation of these proposals could have significant economic, environmental and social impacts in the region.
