PORTLAND, Oregon, Oct. 11 -- The U.S. Army Corps of Engineers-Portland District issued the following news release:
The Oregon Department of Fish and Wildlife determined that the fish died from barotrauma, a condition caused by a rapid pressure reduction as fish pass from deep below the surface on one side of the dam to the other side near the surface level. Among divers, this decompression effect is known as "the bends."
