Welcome to Three Forks Marina


Three Forks Harbor is the result of a vision 30 years in the making. It occupies a cozy niche at the confluence of the Arkansas, Verdigris and Grand Rivers, historically known as "The Three Forks" since the 1700s. These three rivers merge into the McKlellan-Kerr Navigation System which accesses the Mississippi River and ultimately any location in the world that is navigable by water.

Three Forks Harbor is more than just a marina facility. The "River Center" is a new 10,000 square foot multi-use facility that includes office space, conference and meeting facilities, support facilities for boaters, museum-style gallery space, an outdoor plaza and other amenities. Plans are also in place to expand the harbor to include bike trails, RV sites, a restaurant, hotel, and possibly an in-the-water amphitheatre. For more information on these areas, visit the Port of Muskogee website at www.threeforksharbor.org

Travel Lift, Service Yard, and Boat Ramps: 110-ton travel lift. Service yard with 4 service sites, water and 30/50 amp service at each site. Service site rentals available for self-service maintenance projects or dry-dock storage. 2 concrete boat ramps, one 40' wide inside the harbor and one 30' wide on the Arkansas River.

Slip Rentals
: Covered slips are available in 25, 32, 40, 50, and 75-foot lengths. Slips are equipped with water and electrical service (110/220 volt; 30/50 amp service).  Satellite TV is available at the 40, 50, and 75-foot slips for a monthly fee. High-speed WIFI is free and available throughout the marina.  Other free amenities include pumpout and showers/restrooms/laundry facilities at the River Center.
