Bill Williams River National Wildlife Refuge

A 6,150 acre Riparian Habitat. A short ribbon of cool water on the Bill Williams River that flows into the Colorado River between Lake Havasu and Parker, Arizona. Long before Hoover Dam was built at the point the Lower Colorado River began its long descent between the western states of Arizona, California and Nevada to the Atlantic Ocean, there were miles of vegetation marshes, massive stands of Cottonwoods and Willow Salt Cedar Trees creating natural protective habitat for wildlife, migratory birds and now endangered native fish species.

A series of dams were built for flood control, electricity generation and agricultural distribution. Large lakes were formed creating adventurous water recreation environments for for millions of visitors, residents and tourists to enjoy. Unfortunately these lakes also covered up great portions of rich riparian habitat. The building of Alamo Dam on the Bill Williams River also changed the flow of its river which further reduced natural, safe wildlife habit.

The National Fish and Wildlife Department created the protected Bill Williams River National Wildlife Refuge to further protect the native grass marshes, stands of trees and flowing waters that still attracts native wildlife, endangered fish and migrating birds. It is a uniquely beautiful ecosystem where you can look at cattails, cottonwoods and Saguaro Cactus from the same spot. It's also unique in that the various habitats so close together allow for use by a huge diversity of plants and wildlife.

Neotropical birds from Central and South America use this area near the northern end of their migratory routes. Endangered Yuma clapper rails spend the summer months in the cattails of the marsh and may overwinter. Another endangered bird, the southwestern willow flycatcher nests on the refuge in the willow trees lining the river.

Crisscrossing tracks in the sand chronicle the nighttime excursions of cottontails, javelina, and deer, as well as predatory coyotes, bobcats and the less common cougars. Below refuge headquarters lies a cove where razorback suckers and bonytail chubs are raised. The two species are just two of among 31 native Arizona fish. The fish are introduced into the cove, where they grow to around 10 inches. At that point they are released into Lake Havasu and other river areas.

Location and Directions.

The Bill Williams River National Wildlife Refuge is located just east of Highway 95 on the Arizona side between Parker, AZ and Lake Havasu City. From Parker, drive 18 miles north on Highway 95. From Lake Havasu City, drive 15 miles south on Highway 95. The Refuge office is between mile markers 160 and 161 on the Arizona lake side of highway. Most of the cattail marsh in the river delta area can be viewed from turnouts along Highway 95. The riparian area runs eastward from the bridge over the river and can only be accessed on foot.
