Savage Dam is a dam across the Otay River in the San Ysidro Mountains of southwestern San Diego County, California. It is a concrete arch gravity structure high, and serves to store water from the San Diego Aqueduct's third pipeline for backup municipal uses in the San Diego metropolitan area. It is just over southeast of Chula Vista and north of the United States-Mexico border. The dam is named in honor of H. N. Savage, who directed its construction.
