The Missouri National Recreational River
is located on the border between Nebraska
and South Dakota
. The designation was first applied in 1978 to a 59-mile section of the Missouri River
between Gavins Point Dam
and Ponca State Park
. In 1991, an additional 39-mile section between Fort Randall Dam
and Niobrara, Nebraska
, was added to the designation. These two stretches of the Missouri River are the only parts of the river between Montana and the mouth of the Missouri that remain undammed or unchannelized.
The Missouri National Recreational River is managed by the National Park Service. There are visitor centers at Gavins Point Dam and Ponca State Park.
