 Description 
Abstract: White River NWR, DeWitt, Arkansas: White River National Wildlife Refuge lies along 90 miles of Arkansas' White River near its confluence with the Arkansas and Mississippi rivers. Seasonal flooding of these three mighty waterways creates a patchwork of streams, creeks, ponds, and oxbow lakes. In winter, as much as 90 percent of the refuge may be under water, creating paradise for waterfowl such as these mallards. Alternately, the flooding presents a real challenge for upland species such as black bears, forcing them to den and bear their young high up in the trees. But nature provides as the cypress and oaks may have trunks 5 feet across giving the bears adequate den sites.
