Success Dam is located in Tulare County, California and was built in 1961 as a part of the Kaweah River flood control plan. The dam is 203 feet high and 1,100 feet long, and it impounds the Success Lake with a capacity of 82,000 acre-feet. The hydrology of the dam is supplied by the Kaweah River, which is fed by snowpack from the Sierra Nevada Mountains. The dam provides irrigation water for local agriculture, and recreational activities such as fishing, boating, and camping. The surface flow of the Kaweah River is also used for hydroelectric power generation. During periods of drought, the lake is used as a water supply for the city of Porterville. In recent years, the dam has undergone upgrades to improve its safety and reliability in the face of increasing drought and climate change.
