Fall Creek Dam is at river mile 7.2 on Fall Creek, a tributary of the Willamette River, about 20 miles southeast of Eugene, Ore.
Fall Creek Dam is a rockfill structure with a gated concrete spillway and outlet works for regulating lake levels. The dam was completed in 1966 at a cost of $22 million. During flood season, the dams hold back water to regulate downstream flows. Fall Creek Lake provides 115,100 acre-feet of storage and controls runoff from 184 square miles of drainage area.
Fall Creek Dam works in coordination with Lookout Point and Hills Creek dams to provide flood risk management, water quality improvement, irrigation, recreation, and habitat for fish and wildlife.
