Prado Dam

Prado Dam is an embankment dam that crosses the Santa Ana River and holds back water for the region. The structure controls how much water flows downstream and helps manage the supply for multiple counties.

This structure was built in 1941 by the United States Army Corps of Engineers following severe floods in 1938 that showed the need for flood control. The project emerged as a direct response to that disaster.

The area around this structure draws people who use the reservoir for recreation and outdoor activities that shape local life. Visitors experience the water and surroundings as part of how this region connects with nature.

You can explore the area on foot or by car using the available roads and paths around the dam. Plan your visit for cooler parts of the day, as the region gets hot and exposure to sun can be intense.

A mural painted on the spillway catches visitors by surprise when exploring the area, displaying images related to American history. This artwork stands out as an unexpected cultural touch on an engineering structure.
