The North Umpqua Project was constructed between 1947 and 1956. It consists of a series of dams and canals that divert water to the eight developments, each of which has a powerhouse and a dam. The Clearwater No. 1 Development is the uppermost development on the Clearwater River, which has its confluence with the North Umpqua River near Toketee dam. The development includes a 17-foot-high diversion dam located about 8.1 miles upstream of Toketee Lake and impounding 11.8-acre Stump Lake, 13,037 miles of canal and flumes extending from Stump Lake dam to the forebay, a 16.3-acre forebay with total maximum storage capacity of 120.8 acre-feet, a 4,863-foot-long penstock, and a powerhouse with a single turbine-generator having a rated capacity of 15,000 kW. The powerhouse discharges directly into the Clearwater No. 2 diversion.
