Keystone Lake

Keystone Lake provides boat ramp access to the Arkansas River in Cleveland, Pawnee County, Oklahoma. This is a major waterway—the Arkansas River is a significant stream system with an average flow of over 51,000 cubic feet per second and substantial current averaging 6.58 feet/second. A valid day use pass is required for all visitors using the boat ramp. The access point connects paddlers and boaters to a major river system with multiple recreation areas in the vicinity, including opportunities for downstream exploration.

The broader region offers several complementary access points and facilities. Keystone Harbor Marina operates nearby with full amenities including fuel dock, pump-out services, and additional boat ramp access. For those exploring downstream, Swift Park (in Tulsa County) provides boat access to the Arkansas River below the lake when water levels permit, and features additional amenities including camping. Washington Irving South Recreation Area also offers camping and day-use facilities in the area.

Given the Arkansas River's significant size and current (averaging nearly 7 feet per second), paddlers should be prepared for a major river environment. The landscape represents the transition zone from the Flint Hills region, with moderate gradient averaging 7.9 feet/mile. Plan accordingly for the scale and flow characteristics of this major waterway.
