Deforestation has increased soil erosion, blocked streams and elevated water temperatures.

Evidence of the struggle over restoration of salmon and the future fate of some of the dams is seen daily in newspaper headlines. The building of Bonneville dam had drowned the 6-mile stretch ly known as "The Cascades of the Columbia" [5]. Seventy percent of Columbia Basin river and stream miles which had been salmon habitat are now blocked by dams which prevent the migration of adult coho, chinook, and sockeye salmon from the ocean to their upstream spawning grounds [13].

Unfortunately, water falling over spillways can force air bubbles into the water, which can be absorbed into the fishes' tissue, ultimately killing it. Some feel that hybridization will spell the end for truly wild salmon runs [20].

The salmon evolved to become an essential part of a complex ecosystem dependent upon the nutrients and energy that the fish brought back with them from the sea.
