BREACHING DAMS - A CONTROVERSIAL SOLUTION TO SAVING THE SALMON
Introduction
A big controversy in Washington today is whether we should breach our dams to save our salmon. Opponents are squaring off over a controversial proposal to save salmon by breaching four dams on Washingtons Snake River. Each spring, millions of young Chinook salmon in the Snake River have to get past four killers as they make their way out to the open sea. They go by the names of Lower Granite, Little Goose, Lower Monumental, and Ice Harbor. These dams, erected in Washington in the 1960s and 1970s to generate power for the Pacific Northwest, can be just as deadly as any predator, smolts can get pureed by turbine blades or plunge over spillways to their deaths. Survivors are delayed by sluggish water behind the dams that might cripple their ability to adapt to salt water.
