Seven Oaks Dam
Reservoir Levels • Weather • Hydrology
The Seven Oaks Dam is a concrete gravity dam located in San Bernardino County, California. Built in 1999, it stands at 550 feet tall and spans 2,200 feet across the Santa Ana River. The dam was constructed to protect the cities of San Bernardino and Riverside from severe flooding. The hydrology of the region is heavily influenced by snowpack, which is the primary source of surface water for the Santa Ana River. The dam captures water from the river during wet seasons and releases it during dry seasons to support agricultural and recreational activities downstream. The dam has a capacity of 182,000 acre-feet and can hold up to 6.4 billion gallons of water. The area around the Seven Oaks Dam has become a popular destination for hiking, fishing, and other outdoor activities.
