Mud Mountain Dam Inlet Tower

View of Mud Mountain Dam's inlet tower. Mud Mountain was completed in 1948 to protect the lower White and Puyallup valleys by holding back water from heavy rains and snow melt then releasing it slowly into the river. Between flood events, the reservoir is usually empty except for normal flows of the White River. During the December 2025 flood event in western Washington, the dam helped prevent an estimated $215 million in damages along the lower White and Puyallup rivers and protected an estimated 400,000 people. USACE Seattle District is poised to update the dam's water control manual in October 2026, which guides how and when flows are released.

Howard A. Hansom Dam
Howard A. Hanson Dam is located on the upper reach of the Green-Duwamish River in King County, 63 river miles above the mouth. Since dam operations first began in December 1961, the dam has provided flood risk reduction in the Green-Duwamish River Basin by capturing excessive water runoff from the upper drainage area of the river and releasing the water under controlled conditions.
