Mud Mountain Dam typically does not hold a pool
Mud Mountain Dam typically does not hold a pool when not being used for flood control. Operation of Mud Mountain Dam for flood control held back inflow of about 22,500 cfs to 6,000 cfs outflow during the peak of the floods. While inflows have now dropped substantially, the public should be prepared for continued high outflows in the near future as dam operators release stored water to make room in the reservoirs for potential future high inflows. While releases from Mud Mountain Dam are expected to stay below the official flood stage of 8,000 cfs, the Corps will periodically monitor conditions today in the Pacific and Sumner areas on the White River because of the unpredictability of channel capacity there.
