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 Lemolo No. 2 Development includes a 25-foot-high diversion dam that impounds a 1.4-acre pond with no active reservoir storage, 69,503 feet of canal and flumes extending from the diversion dam to the forebay, a 24.2-acre forebay with total storage of 230.6 acre-feet, a 3,975-foot-long penstock, and a powerhouse housing a single turbine-generator with a rated capacity of 33,000 kW. The Lemolo No. 2 dam is about 190 feet downstream of the Lemolo No. 1 powerhouse, and the Lemolo No. 2 powerhouse is about 3,500 feet upstream of Toketee Lake.
