Ducks Unlimited and the U.S. Fish and Wildlife Service (USFWS) has completed a joint project on Oklahoma's Sequoyah National Wildlife Refuge (NWR), which will help maintain the productivity of 1,560 acres of wetlands for waterfowl and other wildlife. The USFWS provided $167,000 in funding for DU to survey, design, and purchase 27 water-control structures. Refuge staff then installed the new water-control structures during late 2011.

Established in 1970, Sequoyah NWR is located in Haskell, Muskogee, and Sequoyah counties in east-central Oklahoma along the Robert S. Kerr Reservoir, just below the confluence of the Arkansas and Canadian rivers. In addition to providing public-hunting opportunities, the refuge is an important late winter and early spring staging area for migrating waterfowl.
