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 Soda Springs Development includes a 77-foot-high diversion dam located on the North Umpqua River about 1.3 miles downstream of the Slide Creek powerhouse, a 31.5-acre reservoir with a total maximum storage capacity of 411.6 acre-feet, a 2,112- foot-long steel pipe extending from the diversion dam to a surge tank, a 168-foot-long penstock extending from the surge tank to a powerhouse, and a powerhouse with a combined turbine-generator set having a rated capacity of 11,000 kW. The storage capacity of Soda Springs reservoir is used to ensure a minimum flow in the North Umpqua downstream of the development.
