Don Pedro Reservoir is a man-made lake situated in the Sierra Nevada foothills of California, about 10 miles from La Grange. This reservoir was created by the construction of the Don Pedro Dam on the Tuolumne River in 1923. It has a storage capacity of 2,030,000 acre-feet and is one of the largest water storage facilities in California. The reservoir serves as a critical source of water for irrigation, hydroelectric power generation, and municipal supply. It is also a popular recreational destination, offering activities such as fishing, boating, camping, and hiking. The reservoir receives its water from various sources, including snowmelt from the Sierra Nevada mountains, rainfall, and surface flow from the Tuolumne River. The snowpack providers are the Sierra Nevada Mountains, and the surface flow is provided by the Tuolumne River. The water from the reservoir is used for agricultural purposes in the Central Valley and in cities such as San Francisco and Modesto.
