Fort Gibson Lake is a 19,900-acre U.S. Army Corps of Engineers reservoir on the Grand Neosho River in Cherokee, Wagoner, and Mayes counties in northeastern Oklahoma — the primary recreational boating destination for the Muskogee and Tahlequah corridor and one of the most productive bass and crappie lakes in the eastern Oklahoma reservoir system. The lake sits in the heart of the Cherokee Nation in the rolling green hills of northeastern Oklahoma, giving Fort Gibson a distinctly different landscape character from the drier western Oklahoma reservoirs. The Grand Neosho River arm and the Illinois River tributary create extensive structure for largemouth and smallmouth bass, crappie, white bass, catfish, and hybrid striper managed by the Oklahoma Department of Wildlife Conservation. Fort Gibson Lake draws consistent tournament fishing traffic throughout the spring and fall seasons and the Wagoner and Fort Gibson communities on the lake’s western and southern shores anchor the primary marina and service infrastructure.
