The dam at  Lake Cuyamaca is the second oldest in California still in use, and was completed in 1888. It was built to supply drinking water to the city of San Diego. It was originally piped down to San Diego in wooden flumes. It continues to be part of the municipal water supply system for San Diego. In the mid 1960s the Lake Cuyamaca Recreation and Park District was formed. Through various projects over time, it has created a more permanent water supply infrastructure and new recreation features at the reservoir.
