The Kiamichi River flow depends on recent rains, so call the one outfitter on the river before making the drive. The Lower Mt. Fork river at Broken Bow is a short bit of paddling, but quite fun. More importantly, it runs most of the time at Class II speed due to being down river from a hydroelectric dam
