Sonny Bono Salton Sea National Wildlife Refuge

The Salton Sea refuge protects the habitat of the endangered Yuma clapper rail.

The refuge, formerly the Salton Sea National Wildlife Refuge, is a sanctuary for wintering waterfowl and other water birds.

Peak bird populations can be viewed during December and January. Endangered species include the Yuma clapper rail, California brown pelican and the desert pupfish.

Habitats include about 35,000 acres of salt marsh and open water, along with 2,200 acres of agricultural fields and freshwater ponds.

The refuge is one of the lowest in the United States, about 228 feet below sea level. Most of the refuge has been inundated by the rising waters of the Salton Sea. Visitors should be prepared for extremely hot weather during summer months.

There is no fishing on the refuge, but anglers can enjoy the sport nearby.
