Forming the border of Nebraska and South Dakota, the Missouri National Recreational River was originally designated in 1978, but only 300 of its 34,128 acres are managed by the National Park Service (NPS). Its lower segment runs 59 miles from the Gavins Point Dam to Ponca State Park. More than a decade later, a 39-mile stretch was added from the Fort Randall Dam to Niobrara State Park, and includes 20 miles of the Lower Niobrara River (which is itself designated a National Scenic River upstream). The section of river in between is a 29-mile long reservoir known as Lewis and Clark Lake, named for the explorers that led the Corps of Discovery up this section of river in August-September 1804.
Lewis and Clark Visitor Center, Gavins Point National Fish Hatchery and Aquarium, boating, fishing
Most visitors come for the boating and fishing opportunities along the Missouri River. If you are well-prepared, canoeing can be a fun way to experience these two relatively free-flowing sections of river. The NPS and U.S. Army Corps of Engineers (COE) manage the Lewis and Clark Visitor Center near Yankton, South Dakota, which, in addition to dam tours, offers the Gavins Point National Fish Hatchery and Aquarium.
The 4,400-mile long Lewis and Clark National Historical Trail tracks through here, but since the Corps of Discovery used the Missouri River as their path, there is no hiking trail to follow.
There are several great museums along the Missouri River section of the Lewis and Clark National Historical Trail. Our favorite is the NPS headquarters for the trail in Omaha, Nebraska, which has the beautiful Bob Kerrey Pedestrian Bridge across the river connecting to Iowa. If you drive over to Council Bluffs, do not miss the free museum at the Western Historic Trails Center.
None for the NPS unit, but the state parks charge admission.
Roads to the state parks and visitor centers are paved, but there are many dirt roads that access boat launches along the river.
Niobrara State Park and Ponca State Park both have more than 100 campsites with running water. The COE also operates campgrounds near its dams.
