Isabella Lake in California is a remarkable 11,200-acre reservoir located in the Sierra Nevada foothills within Sequoia National Forest. Created in 1953 by the U.S. Army Corps of Engineers, this man-made lake sits at an elevation of about 2,500 feet, which helps maintain cooler water temperatures despite its southern location. The lake was formed by two dams—the Main Dam and Auxiliary Dam—built at the confluence of the North and South Forks of the Kern River. Once home to the communities of Kernville and Isabella before being flooded, Lake Isabella today offers diverse fishing opportunities in a scenic desert mountain setting. Its depth averages around 55 feet with a maximum depth of 185 feet when full, creating various habitats that support multiple fish species.
