Mammoth Pool is a reservoir located in the Sierra National Forest of California. The history of the reservoir dates back to the early 1900s, when it was constructed as part of the San Joaquin Electric Company's hydroelectric system. The reservoir is fed by several creeks and streams, including the San Joaquin River, as well as snowpack melt from the surrounding mountains. The hydrology of the area is complex and includes a network of aqueducts and pipelines that deliver water to agricultural and urban areas in the Central Valley. The surface flow from Mammoth Pool is used for irrigation in the Fresno area, while the snowpack provides important water resources for the state. The reservoir is also a popular recreational destination, with opportunities for fishing, boating, and camping.
