Study looks at benefits and liabilities of Snake River dams

SPOKANE, Wash. (AP) — A state report says four federal hydroelectric dams along the Snake River in Washington state bring both benefits and liabilities to the region, and there is no clear consensus on whether the giant structures should be removed or retained. The report released Friday says the dams are blamed by many for declining salmon runs in the Columbia-Snake river system. The salmon are a key food source for killer whales, which are also endangered. The four dams are Ice Harbor, Lower Monumental, Little Goose and Lower Granite, and they are located on the Snake River between the Tri-Cities of Washington and Lewiston, Idaho.
