This is a tale of three rivers.
While most casual observers would say the the Beaver is spawned by Optima Lake in Texas County, the actual origin of the river is the Corrumpa River which rises in New Mexico flowing into the Panhandle, taking a brief six -mile sashay into Texas, and returning to Oklahoma west of Texhoma flowing northeasterly for a time before bending to the east near Guymon and emptying into the lake.
Upon leaving Lake Optima, the Beaver flows east, northeast, east again and finally southeast to a point near Fort Supply Lake where it becomes the North Canadian River. The river lends its name to the town of Beaver, Beaver County and Beaver Dunes State Park.
