San Luis Dam

San Luis Dam is an embankment dam that creates a large reservoir for water storage across the region. The structure rises approximately 188 meters (615 feet) and functions as one of the nation's largest off-stream storage facilities.

Completion of the dam in 1967 marked a turning point in California's approach to water management during agricultural expansion. The project established new standards for embankment dam construction and water storage technology.

The valley now beneath the reservoir was home to the Yokuts people before agriculture transformed the land. Few reminders of this earlier presence remain visible today.

The area around the dam features viewpoints and rest areas where visitors can observe the reservoir and surrounding landscape. It is best to arrive early and prepare for variable weather, as the area can be windy and exposed.

The construction introduced the first tower cranes in America, developed specifically to build the four intake towers. This innovation reshaped how similar dam projects were built across the country.
