SEATTLE
– The U.S. Army Corps of Engineers, together in collaboration with other federal agencies and others in the Mid-Columbia Region, will conduct spill tests at Chief Joseph Dam near Bridgeport, Wash., April 28 – May 1. The purpose of the test is to evaluate the effectiveness of recently installed flow deflectors at reducing total dissolved gas concentrations downstream of the dam.
For four days next week the Corps will perform a series of 12 tests, three hours each, during daylight hours. Spill amounts will be as low as 18,000 cubic feet per second (cfs) to as high as 145,000 cfs, spread across all 19 spill bays. The maximum river flow during the tests is not expected exceed 235,000 - 240,000 cfs, approximately the same level seen during the spring melt in 2008.
Besides the lower river, the reservoir above Chief Joseph Dam, Rufus Woods Lake, may be operated below the normal operating pool of 950 feet to facilitate spills at the dam. The lowest elevation the pool may reach would be 947 feet, during those four days Apr. 28 - May 1, 6 a.m. to midnight.
Safety is always a primary concern of the Corps. Those people living, playing and working on or near the river are urged to be aware and be cautious for changing river condition
