Crystal Springs Reservoir, Water reservoir in San Mateo County, California, US.
Crystal Springs Reservoir comprises two artificial lakes situated in the northern Santa Cruz Mountains along the San Andreas Fault rift valley.
The Spring Valley Water Company constructed the Lower Crystal Springs Dam in 1888, submerging the former resort town of Crystal Springs beneath its waters.
The reservoir forms part of San Francisco's water infrastructure, supplying residents while preserving the surrounding natural environment for future generations.
Visitors can explore the Crystal Springs Regional Trail that extends along the reservoir's edge, offering views of local wildlife and natural landscapes.
The reservoir contains water from local precipitation mixed with water transported through pipelines from Hetch Hetchy Reservoir in Yosemite National Park.
