🚧 Salinas Dam

The Salinas Dam is a dam built on the Salinas River in San Luis Obispo County, California. Designed by Raymond A. Hill, the gravity dam features an arched design with an open spillway. The War Department began construction on the dam in mid-1941, as World War II began to reach the Pacific. The original intent of the dam was to supply water to Camp San Luis Obispo, which the Army was considering expanding to meet military needs. However, the camp's wells ultimately provided sufficient water to the camp, and the reservoir water was never required or used by the military. Today, the dam operations are leased by the city of San Luis Obispo, to supply water to the city and surrounding agricultural areas. The reservoir created by the dam is known as the Santa Margarita Lake, or Santa Margarita Reservoir.
