Havasu National Wildlife Refuge

Havasu National Wildlife Refuge is a U.S. National Wildlife Refuge on the lower Colorado River in Arizona and California. It preserves habitat for wildlife like desert bighorn sheep, the endangered southwestern willow flycatcher, the threatened Yuma Ridgways Rail and other animals. The refuge protects 30 river miles - 300 miles (480 km) of shoreline - from Needles, California, to Lake Havasu City, Arizona. One of the last remaining natural stretches of the lower Colorado River flows through the 20-mile-long (32 km) Topock Gorge.
