Tulloch is a reservoir located in the Sierra Nevada Mountains of California. It was created in 1955 with the construction of the Tulloch Dam on the Stanislaus River. The reservoir has a total capacity of 83,000 acre-feet and is used to provide irrigation water for agriculture and to generate hydroelectric power. The hydrology of the area is heavily impacted by the snowpack in the surrounding mountains, which provides a significant amount of the surface flow into the reservoir during the spring and summer months. The lake is a popular destination for recreational activities such as boating, fishing, and camping. The surrounding area is also home to many vineyards and orchards that rely on the irrigation water provided by the reservoir.
