The Refuges

As an all-volunteer nonprofit, we assist Refuge staff efforts in many ways

The U.S. Fish & Wildlife Service's Lake Havasu National Wildlife Refuge Complex consists of two distinct refuges: the Bill Williams River National Wildlife Refuge, and it's counterpart, the Havasu National Wildlife Refuge. Both refuges are located in the lower Colorado River valley of western Arizona.


In relation to Lake Havasu City, Bill Williams River is to the south, Havasu is to the northwest.


The southernmost of the two Refuges, the Bill Williams River NWR, is located between Lake Havasu City and Parker (approximately 24 miles south of Lake Havasu City). The "Bill Will," as it
is affectionately referred to by it's many fans, is located on the extreme southern end of Lake Havasu. This Refuge encompasses a portion of Lake Havasu, as well as the Bill Williams River riparian habitat, which offers one of the last stands of cottonwood-willow forest along the lower Colorado River.

The northernmost of the two Refuges, the Havasu NWR, is located between Lake Havasu City, Arizona and Needles, California. Interstate 40 passes through this Refuge as it crosses the Colorado River. The Havasu NWR includes approximately 300 shoreline miles of river, lake, and marsh habitat between Lake Havasu City and Needles. The Topock Marsh is located north of the Interstate 40 crossing. Topock Gorge and the Havasu Wilderness Area are located south of the Interstate 40 crossing. Topock Marsh, Topock Gorge, and the Havasu Wilderness Area are all distinct attractions in their own right.

Both Refuges are home to an amazing variety of migratory and resident wildlife, and offer the opportunity to experience wonderful recreational opportunities!​
