Bill Williams River National Wildlife Refuge

Along the lower Colorado River, tall gallery forests of Fremont cottonwood and Goodding's willow once lined the banks for miles. These forests depended on the river's natural cycle of floods, which scoured out bare ground and laid down the moist soil the seedlings needed. When the great dams tamed the Colorado, they ended those floods, and much of the native forest slowly died out or was replaced by invasive salt cedar.

The Bill Williams refuge protects one of the best remaining stands of that vanishing forest. Managed with the health of the woodland in mind, it keeps alive a habitat that once defined the lower Colorado and now survives only in fragments. To walk beneath its cottonwoods is to see the river country much as it looked before the dams changed everything.

The refuge is best known to birders. Its combination of river forest, marsh, open water, and surrounding desert packs an unusual variety of habitats into one place, and that variety draws an equally varied cast of birds. The lower Colorado is a key corridor of the Pacific Flyway, the great north-south migration route, and during spring and fall the refuge fills with travelers on the wing.

Herons and egrets stalk the shallows, waterfowl raft on the backwaters, and songbirds fill the cottonwoods, while raptors ride the thermals above the desert ridges. Among the refuge's most prized residents are secretive marsh birds and southwestern songbirds that depend on exactly this kind of riverside forest. For the patient watcher, a morning here can turn up a long and surprising list.

Part of what makes the refuge special is the dramatic meeting of green and gray. The lush river forest and marsh sit at the foot of rugged, rocky desert mountains, and the contrast could hardly be sharper. Step from the shade of the cottonwoods and within a short distance you are in classic Sonoran and Mojave desert, all creosote, cactus, and bare rock.

That edge, where two very different worlds meet, is part of why the refuge holds so much life. Desert animals come to the water, river creatures shelter in the marsh, and the whole place hums with activity that the surrounding dry country cannot match. Bighorn sheep range the desert slopes above, and beaver and other water-loving animals work the river below.

The refuge lies in the heart of the lower Colorado River country, a stretch of the river famous for its blue water, its resort towns, and its long, hot summers. Nearby Parker and Lake Havasu City draw crowds to the water for boating and fishing, and the region has a lively river-recreation culture.

Against that busy backdrop, the Bill Williams refuge offers something different, a place of quiet and native wildness where the river is left to nourish its old forest and its wildlife. It is a reminder of what the whole lower Colorado once was, tucked into a corner of Arizona that most travelers pass without knowing it is there.
