Natural History
The Bill Williams River National Wildlife Refuge protects the lower course of the Bill Williams River, to its mouth at Lake Havasu reservoir, in western Arizona. It is located within eastern La Paz and Mohave Counties, in the Lower Colorado River Valley region. The federal wildlife refuge is managed by the United States Fish and Wildlife Service. Recreation activities include nature walks, bird watching, hiking, and kayaking on the Bill Williams River. The Nature Conservancy acquired the land from the Arizona Ranch and Metals Company in 1977 and donated it to the Fish and Wildlife Service.
