Lower Illinois River

Flowing from the base of Lake Tenkiller Dam to its confluence with the Arkansas River, the Lower Illinois River offers a unique blend of natural beauty, recreation and Oklahoma heritage.

Fed by the clear, cold waters released from Lake Tenkiller, this scenic stretch of river winds through forested hills, rocky shorelines and picturesque river valleys. Known for its excellent trout fishing, abundant wildlife and peaceful paddling opportunities, the Lower Illinois provides visitors with a quieter, more relaxed outdoor experience while showcasing some of the Oklahoma Ozarks' most beautiful landscapes.
