SEATTLE -- U.S. Army Corps of Engineers emergency management teams are out at river basins around western Washington monitoring levee conditions, dispersing sandbags and preparing to bring in heavy equipment should it be needed. The Seattle District Reservoir Control Center began 24-hour operation Nov. 5 and will continue to operate around the clock for the foreseeable future.
Flood fight personnel from the Corps are out in the Skagit, Snohomish, Nooksack, Chehalis, Green, and Puyallup River basins and the Olympic Peninsula. They have been requested by local officials to provide assistance. The Corps has already sent out 35 flood team members and provided thousands of sandbags to Skagit and Snohomish County and the town of Stehekin to aid in their flood fighting efforts.
The Corps is operating dams on the Green, White, Skagit and Wynoochee rivers for flood damage reduction. While the Corps can regulate flows on these rivers, the dams only regulate about 40 percent of the flows in the Skagit and White/Puyallup basins.
At 4 p.m. this afternoon Mud Mountain Dam on the White River had inflows of 18,000 cubic feet per second and the Corps was holding outflows to less than 1,000 cfs. Outflows will stay at less than 1,000 cfs for at least the next few hours.
Wynoochee Dam is receiving about 11,200 cfs of inflow, with inflows expected to recede later this evening. The Corps is holding outflows from Wynoochee Dam to the minimum of 220 cfs.
Howard Hanson Dam on the Green River is receiving about 15,000 cfs inflows and passing 3,000 cfs out of the dam. The forecast is for inflows as high as 20,000 cfs.
In the Skagit River basin, the Corps is regulating Upper Baker and Ross dams. At Ross, inflows are 30,000 cfs, and the Corps is not allowing any outflow as of this morning. Upper Baker inflows are 30,000 cfs, and outflow is being held to 5,000 cfs.
