Lower Mountain Fork River is one of the best whitewater rivers in Oklahoma. With consistent flowing water it can be run year-round. It is a popular river and brings paddlers from North Texas, Louisiana and Arkansas. Trees line the undeveloped banks of the river where visitors enjoy camping, fishing and swimming. Beginning at Reregulation Dam, the river offers several technical Class II rapids. This is a short section that can be run several times in a day or you may continue further down stream to flat-water.
