Vasona Reservoir is an artificial lake located in Los Gatos, California, United States. A 152-acre (62 ha) county park surrounds the reservoir[4] and provides limited fishing[5][6] ("catch and release"), picnicking, and informal play activities. Although swimming is not allowed,[7] human-powered boating is permitted in the reservoir.[8]


The reservoir was formed by the Vasona Percolating Dam, built in 1935 across Los Gatos Creek.[9] It is the smallest reservoir owned by the Santa Clara Valley Water District.[10]

Albert August Vollmer, who came to the area in 1887, named the area after a pony he had had as a child.[9]

Vasona Dam[edit]

Vasona Dam is an earthen dam 34 feet (10 m) high and 1,000 feet (300 m) long. Its crest is 307 feet (94 m) above sea level.[3] New gates were installed in the dam in 1997.[9]

Vasona Lake County Park[edit]

Vasona Lake County Park[4] is one of 28 Santa Clara County Parks.[11] The 152-acre (62 ha) park surrounds the reservoir, with Oak Meadow Park adjacent to the west. The reservoir offers fishing for black bass, crappie, catfish and bluegill.[4][12]
