Keystone WMA covers 22,393 acres of Creek, Osage, and Pawnee Counties in north-central Oklahoma. Located near the towns of Cleveland, Mannford, and Oilton, Keystone WMA is comprised of the Arkansas and Cimarron rivers and adjacent flood plains and bottomlands.
The Arkansas and Cimarron Rivers are wide shallow major drainages in the state and with their sandbars, they comprise about 20% of the WMA acreage. Adjacent to the rivers are forests dominated by willow and cottonwood. As the elevation rises from the rivers, the WMA transitions to a mixture of bottomland hardwood trees, cropland fields, old fallow farm fields, and smaller areas of upland habitat. There are numerous sloughs, natural and man-made wetlands, and mudflats where the rivers deposit silt into the lake. Much of the water on the WMA is too shallow for boat traffic unless the lake elevation is high.
