River Summary: The Bill Williams River is a 46-mile-long tributary of the Colorado River in western Arizona. It is named after mountain man Bill Williams, who explored the area in the early 19th century. The river flows through the Bill Williams National Wildlife Refuge and the Lake Havasu National Wildlife Refuge before joining the Colorado River near Lake Havasu City. The Bill Williams River is fed by several tributaries and is regulated by several dams and reservoirs, including the Alamo Dam and Reservoir, which provides water for agriculture and recreation. The river also supports recreational activities such as boating, fishing, and camping, and provides habitat for a variety of wildlife, including the endangered southwestern willow flycatcher. In recent years, efforts have been made to restore and protect the Bill Williams River and its ecosystem.
