Unusual for February, a little water spilled over Grand Coulee Dam Wednesday, Feb. 7, as repairs were made to a generator while the need to lower the lake for runoff continued. - Scott Hunter photo
The Grand Coulee Dam spilled water over the top last week due to anticipation of spring runoff, combine with minor maintenance being performed on a generator.
"Inflows into Lake Roosevelt are up slightly," said Lynne Brougher, Public Affairs Officer for the Bureau of Reclamation. "We needed to continue to move water downstream to prepare Lake Roosevelt for the spring runoff."
Brougher also said that generator 24 was undergoing some minor, unexpected maintenance, and that spillage over the dam was performed to compensate for the generator being down.
"With G-24 back online, enough water is able to pass through the generators to not have to continue spilling," she said.
Lake Roosevelt's surface elevation was at 1,277 feet above sea level on Feb. 6, and had lowered to 1,272 by Feb. 13.
