San Antonio River (California)

The San Antonio River is a river in southern Monterey County, California. San Antonio Dam, an earth-fill dam on the river, forms Lake San Antonio, the largest lake in the county. Before it reaches the lake, the river travels southeast from its headwaters in the Coastal Range. Downstream from the dam, the river travels east until it joins the Salinas River. The Nacimiento River, which feeds Lake Nacimiento and is also a Salinas River tributary, mirrors San Antonio's path several miles to the southwest.
