About the Trail


The Missouri National Recreational River Water Trail extends from Ft. Randall Dam near Pickstown, SD to Sioux City, IA. Most of the Water Trail lies within the boundaries of the Missouri National Recreational River (MNRR), a National Park unit consisting of relatively free-flowing segments of the Missouri River.


The 39-mile segment extends from Ft. Randall Dam to near Running Water, SD. The 59-mile segment begins just below Gavins Point Dam and ends just downstream of Ponca State Park. The Water Trail covers the entire length of the 39 and 59-mile segments.


Although not part of the MNRR, Lewis and Clark Lake is included within the Water Trail, to allow a connection for paddlers between the 39-mile and 59-mile segments. The Water Trail also extends approximately 20 miles beyond the downstream boundary of the 59-mile segment to Sioux City, IA.


National Water Trail System Designation

The MNRR Water Trail is now part of the National Water Trail System! View the press release.
