Two segments of the Missouri River are administered by the National Park Service as the Missouri National Recreational River. They are also in the National Wild and Scenic River System. Today, these sections look much like they did in the early 1800s during the Lewis and Clark expedition. Due to the currents and sudden windstorms, these segments are for experienced paddlers only. The first segment is 39 miles from the Randall Creek Recreation Area at Pickstown to Running Water. The second segment is 59 miles long from below Gavins Point Dam to Ponca State Park in Nebraska.
