Touted as a big win for fish, a plan to increase springtime spill at eight federal dams on the Columbia and Snake rivers was approved last week by a federal judge.,, Spill is a term for allowing water to flow over a dam instead of passing that water through turbines that generate electrical power. Out-migrating juvenile salmon and steelhead smolts that pass through these turbines are often killed, either directly or by delayed mortality. Spill allows more smolts to escape the turbines and results in a greater return of adult fish. >click here to read<19:22
