Anderson Lake, also known as Anderson Reservoir, is an artificial lake in Morgan Hill, located in southern Santa Clara County, California. The reservoir is formed by the damming of Coyote Creek just below its confluence with Las Animas Creek. A 4,275-acre (1,730 ha) county park surrounds the reservoir and provides limited fishing ("catch and release"), picnicking, and hiking activities. Although swimming is prohibited, boating, water-skiing, and jet-skiing are permitted in the reservoir. The California Office of Environmental Health Hazard Assessment has issued a safety advisory for any fish caught in Anderson Lake due to elevated levels of mercury and PCBs. From Wikipedia
