The Inland Deserts Region Fisheries Program manages diverse fish and amphibian resources, and the habitats upon which they depend, for their ecological values and for their use and enjoyment by the public. The Region spans 43,326 square miles across 5 counties (Imperial, Inyo, Mono, Riverside, and San Bernardino) serving a
population of over 4.8 million people and containing a multitude of unique habitats supporting a wide variety of aquatic species. These diverse resources range from Sierra Nevada Mountain Yellow Legged Frog populations in the Eastern Sierra mountains (at 11,000 feet above sea level), to Death Valley Pupfish (at 200 feet below sea level); from wild trout throughout Mono, Inyo, San Bernardino, and Riverside counties, to recreational fisheries in urban and rural lakes and reservoirs. Environmental Scientists lead numerous threatened and endangered fish recovery efforts throughout the Inland Deserts Region. Additionally, Interpretive Staff support public aquatic education programs, including the Trout in the Classroom Program, and provide free fishing opportunities with equipment available for loan throughout Imperial, Inyo, Mono, Riverside, and San Bernardino Counties.
