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 Slide Creek Development includes a 30-foot-high diversion dam located on the North Umpqua 900 feet downstream of the Toketee powerhouse and impounding a 2-acre reservoir with maximum total storage capacity of 43 acre feet, 9,653 feet of canal and flumes extending from the dam to the penstock, a 374-foot-long penstock, and a powerhouse with a single turbine-generator having a rated capacity of 18,000 kW. The powerhouse is located on the North Umpqua 1.3 miles upstream of Soda Springs dam.
