Cibola National Wildlife Refuge was established in 1964 as mitigation for the straightening, channelization, and armoring of the banks of the Colorado River by the Bureau of Reclamation to prevent flooding. The purpose of the 18,444-acre refuge is to protect and recreate the marshes, backwaters, and meanders that historically provided wintering grounds for migratory waterfowl and other wildlife that natural flooding would have formed.
