GRAND COULEE - The U.S. Bureau of Reclamation will conduct a dye test Aug. 8 at Grand Coulee Dam.
The dye is safe for the environment and harmless to animals and humans, but the pool below the dam may be slightly discolored as engineers inject the upstream face of Grand Coulee Dam with a biodegradable blue dye, dam officials said.
The movement of the dye will help to determine the path of seepage near the Right Powerhouse. Seepage has been present and slowly increasing for a number of years; the test will aid engineers in planning maintenance.
"This dye test will ensure the efficient operation of Grand Coulee Dam and continued reliability to provide electrical power in the Pacific Northwest," Power Manager Mark Jenson said. "The seepage near the Right Powerhouse poses no danger to the public and the condition of the dam is sound."
Grand Coulee Dam produces enough electricity to supply more than 1 million homes in an average water year. The project also provides about one-quarter of the total generation of hydroelectric power for the Federal Columbia River Power System.

State Department of Fish and Wildlife Sgt. Dan Christensen recorded this video of the release of a mama bear and her three cubs Friday, Sept. 11, 2015. The bears were captured in a tree at Esther Bricques Winery near Ellisforde. The original video was much longer. We've edited out several minutes of footage between the cubs leaving the first trap and the mama and cub leaving the second trap. Enlarge
