Located at River Mile 392.2 of the McClellan-Kerr Arkansas River Navigation System, near the confluence of the Arkansas, Verdigris and Grand Rivers, Three Forks Harbor offers the boating public its most-inland all-weather access to the nation’s waterways and sea ports of the world – and much more! The centerpiece of Three Forks Harbor is the River Center, a 10,000 square foot multi-purpose events center and plaza, designed by GH2 Architects. You will also find state-of-the-art marina facilities managed by the Muskogee Port Authority. Truly a mixed-use port development, Three Forks Harbor is fast becoming a focal point for the enjoyment and appreciation of one of the nation’s premier waterways. A perfect setting for boaters, fishermen, hikers, bikers and other outdoor enthusiasts, Three Forks Harbor is already home to such events as Kids Fishing Rodeo, River Rumba, Cardboard Boat Regatta and Bassmaster Opens. We’d love to help you plan an event. Hope to see you soon.
