SaveWaterdog Lake & Open Space (together with the incorporated John S. Brooks Memorial Open Space and the adjoining Hidden Canyon Park, commonly referred to collectively as "Waterdog") contains over 260 acres of open space and a multi-use trail system located in Belmont, California, 25 miles south of San Francisco. While the City of Belmont oversees its management, volunteers from the mountain biking community have long contributed to trail building and maintenance efforts in the open space.
William C. Ralston, founder of the Bank of California, originally commissioned the lake to collect spring water to funnel to his summer home—now known as Ralston Hall Mansion. Following Ralston’s death, the Sisters of Notre Dame de Namur acquired the land, leasing it to the City of Belmont in 1965. In 1978, John S. Brooks donated an additional 51 acres to the City of Belmont—dedicated as the John S. Brooks Memorial Open Space—which are now incorporated into this Open Space.
