The dam is responsible for regulating the water flow of the Santa Ana River, which is the largest river in Southern California. The hydrology of the area is heavily influenced by snowpack and surface flow from the San Gabriel Mountains and San Bernardino Mountains. The dam provides water for various agricultural uses in the region as well as for recreational purposes at nearby parks and reservoirs. The area around the dam is also home to a variety of wildlife, including endangered species like the Santa Ana sucker fish.
