Fish Spill
Photograph by Jim Richardson

The Columbia roars from the spillway of Bonneville Dam during spring runoff, when dam managers “spill for fish” in an attempt to simulate spring freshets that helped move smolts to sea before the river was dammed. Unfortunately the procedure can supersaturate the water with bubbles of nitrogen and other atmospheric gases that harm the smolts. The Army Corps of Engineers has structurally modified some dams in an attempt to reduce gas levels.
