Description
The entire reservoir consists of two different reservoir lakes, split by an earthen dam on which SR 92 crosses the reservoir. The southern reservoir, Upper Crystal Springs Reservoir, is dammed by the earth dam. The northern reservoir, Lower Crystal Springs Reservoir, is dammed by the Crystal Springs Dam (San Mateo County, California), which discharges to San Mateo Creek. Part of the water in the reservoir comes from local precipitation and the rest is piped in from the Hetch Hetchy Reservoir in Yosemite National Park. The entire reservoir was built and owned by a private company, in the form of the Spring Valley Water Company, and eventually was deeded under the ownership and protection of the city of San Francisco. This local protection has ensured the survival of important species in the area, and a set of trails in Crystal Springs Park allows many to enjoy the scenic beauty of the reservoir and the local wildlife.
Flora and fauna
A considerable biodiversity of flora and fauna exist in the vicinity of the reservoir, which is located within the California Floristic Province. Among these species are a number of rare and endangered species including Acanthomintha duttonii or San Mateo thornmint, Hesperolinon congestum (Marin Dwarf Flax) and Eriophyllum latilobum or San Mateo Woolly Sunflower.
