Plan to restore salmon calls for removable spillway weirs

Article Abstract:

As part of an effort to replenish salmon populations in the Pacific Northwest, the federal government intends to modify several dams along the Columbia and lower Snake rivers to include removable spillway weirs and other means for helping juvenile salmon pass through the structures unharmed. The weir makes it possible for fish to enter the spillway closer to the surface of the water and exit by way of a gradually sloping discharge chute that does not involve high pressures and velocities.
