Fish and Wildlife Service, California.
Except for pronghorn antelope hunting during the regular California State seasons, the refuge is closed to public access to protect fragile habitats and to reduce disturbance to wildlife. Clear Lake is also a reservoir and is the primary source of water for the agricultural program of the eastern half of the Klamath Basin with water levels regulated by the U.S. Bureau of Reclamation.
Travel south on State Highway 139 for 20 miles from the town of Tulelake, California. Turn east onto Clear Lake Reservoir Road; and travel approximately 10 miles to the refuge's south boundary. The roads leading to the refuge are not paved and 4 wheel drive is suggested.
