Santa Ana River

The Santa Ana River is a major waterway flowing approximately 96 miles through Southern California, originating in the San Bernardino Mountains and emptying into the Pacific Ocean. It supports local ecosystems, provides water for agriculture and cities, and plays a key role in flood control. The river passes through urban areas like Riverside and Anaheim, and its watershed covers a large part of the region, making it vital for environmental health and community development. Efforts are ongoing to restore natural habitats along its course while managing water resources efficiently.
