The U.S. Army Corps of Engineers has been spilling a small amount of water at one of the Bonneville Dam spillways since Dec. 1, 2003 in order to attract salmon and steelhead to one of the dam’s fish ladders. With a combined average of four hatchery and listed fish passing the dam per day, the Technical Management Team today agreed to end the spill until more fish are present, but it didn’t agree on how many fish must be present before the attraction spill should be turned on again.
