Founded in 1977, the Sea and Desert Interpretive Association (SDIA) is a 501 (c) 3 non-profit organization which is dedicated to supporting and promoting educational and interpretive programs allowing the public to become aware of the uniqueness of this large body of water. The Salton Sea sits 235 ft. below sea level and is bordered by two mountain ranges. Come view this incredible contrast of geology: a large body of water in a desert valley that’s bordered by two mountain ranges, and a fertile agricultural area.

The Sea and Desert Interpretive Association (SDIA) is partnered with Salton Sea State Recreation Area and Sonny Bono Salton Sea National Wildlife Refuge Complex. Both entities are located on the eastern side of the Salton Sea, along Highway 111.

The Association operates Visitor Centers at both locations, which are staffed by volunteers (SBSSNWR) and park staff (SSSRA). Numerous informational books, DVDs, maps, pamphlets and other materials are available. Free 8-minute video programs are offered to visitors about the roles of the State Park and Wildlife Refuge and the Salton Sea.

As part of its support program, the SDIA uses the money raised in the Visitor Centers to furnish equipment and supplies to Park and Refuge staff and provides special funding for various educational and interpretive programs and community events.

The Sea and Desert Interpretive Association members enjoy a 10 percent discount on any merchandise purchased at the Visitor Centers’ gift shops.
