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. 2 Development includes an 18-foot-high diversion dam on the Clearwater River 140 feet downstream from the Clearwater No. 1 powerhouse, a 1.2-acre impoundment with no active storage, 31,235 feet of canal and flumes extending from the diversion dam to an 8.6-acre forebay with total maximum storage capacity of 70.7 acre-feet, a 1,169-foot-long penstock, and a powerhouse on the North Umpqua River at Toketee Lake with a single turbine-generator having a rated capacity of 26,000 kW.
