Idaho Statesman: Fisheries scientists redefine the salmon debate by trumpeting more ‘spill’

Increasing the amount of water spilled over eight Snake and Columbia river dams to keep juvenile fish away from hydroelectric turbines might be enough to recover most of Idaho’s endangered salmon populations without breaching dams, new studies suggest.
