Havasu National Wildlife Refuge
From desert bighorn sheep to the endangered southwestern willow flycatcher, birds and other animals at Havasu National Wildlife Refuge rely on the life-giving waters of the lower Colorado River. The refuge protects 30 river miles - 300 miles 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 Topock Gorge.
From Interstate 40, watch for a Havasu NWR exit sign close to the California/Arizona border. Follow the signs to the refuge.
To reach Topock Marsh from Needles, California, cross the Needles bridge into Arizona following Highway 95 north, then turn right onto Courtwright Road and watch for the refuge sign.
The refuge office is in Needles, California. From Interstate 40, exit on J Street and go southwest (uphill) 0.06 miles. Turn right at headquarters entrance sign and follow the signs; the office is in the back.www.hobogrill.org
