Two-thirds of the "Mighty Mo" has been dammed, channelized
or otherwise "tamed" by the works of man. Missouri National
Recreational River preserves 98 miles of relatively natural,
free-flowing Missouri River, designated by Congress under the Wild and Scenic Rivers Act. MNRR also includes the lower 20 miles of the Niobrara River and the lower 8 miles of Verdigre Creek.
"[T]o conserve the scenery and the natural and historic objects and wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."
