Controlling the flow

As some 203,000 cubic feet of water per second flows downstream of Grand Coulee Dam Sunday evening, about 58,000 cfs comes down the spillway through seven outlet tubes while the Bureau of Reclamation coordinates river flow for flood control. The current forecast calls for Lake Roosevelt to be lowered to 1,222.7 feet above sea level to accommodate expected high snow melt runoff, which has not actually started down the river yet. - Scott Hunter photo
