Massive Fish Kill Blamed on Columbia Dam Releases

Posted By on Sun, May 29, 2011 at 11:06 AM

Huge releases of water from dams on the bloated Columbia River have caused a massive fish kill at a fish farm south of the Grand Coulee Dam. Operators at Pacific Aquaculture said they're losing 100,000 fish a day because the water releases are oversaturating the river with gases that are toxic to the fish.

Cooler temperatures and wetter-than-normal conditions in the Pacific Northwest mean the biggest portion of the expected runoff volume is yet to come, with sub-basin snowpacks running 120 percent to 200 percent of normal in many places.

Meanwhile, weekend rainfall continues to keep the Boise River above 9.8 feet at the Glenwood Bridge, running more than 6,700 cubic feet per second.
