Clear Lake National Wildlife Refuge

Clear Lake National Wildlife Refuge is a National Wildlife Refuge of the United States in northeastern California. It includes about 20000 acre of open water surrounded by over 26000 acre of upland bunchgrass, low sagebrush, and juniper habitat. small, rocky islands in the wetlands provide breeding sites for American white pelicans, double-crested cormorants, and other colony-nesting birds.

The uplands are inhabited by pronghorn, mule deer, and sage grouse. The Clear Lake Reservoir is the primary source of water for the croplands of the eastern Klamath Basin, with water levels regulated by the Bureau of Reclamation.

Except for limited pronghorn and waterfowl hunting during the state hunting seasons, the refuge is closed to all public access for the protection of habitat and wildlife.
