Missouri River Trail

The Missouri River Trail follows the corridor of the Missouri River across the north-central United States, linking headwaters near Three Forks, Montana with the confluence at St. Louis, Missouri. The trail concept unites multiple existing pathways, water routes, and historic roads associated with the river, integrating federal and state routes with local greenways. Planning emphasizes connections among Lewis and Clark National Historic Trail, Missouri National Recreational River, Big Muddy National Fish and Wildlife Refuge, and urban waterfront projects such as those in Omaha, Nebraska and Kansas City, Missouri.

Route and Description

The route concept traces the Missouri River from its source at Hell Roaring Creek near Brower's Spring through Gallatin County, Montana, following corridors used by the Missouri River mainstem past Fort Benton, Montana, Bismarck, North Dakota, Pierre, South Dakota, Fort Randall, Nebraska City, Nebraska, Council Bluffs, Iowa, and terminating at St. Louis, Missouri. Segments incorporate the Lewis and Clark National Historic Trail alignments, floodplain trails in the Missouri National Recreational River, urban riverfronts in Sioux City, Iowa, Omaha, Nebraska, and Kansas City, Missouri, and port-adjacent trails near St. Charles, Missouri. The corridor crosses major crossings like the Glenns Ferry Bridge approach, navigational locks and dams such as Gavins Point Dam and Fort Randall Dam, and conservation lands including Conservation Reserve Program tracts and Prairie Pothole Region fringes. Surface types range from paved bicycle boulevards near Lincoln, Nebraska to gravel levee roads by Blair, Nebraska and primitive footpaths through Loess Hills and riparian cottonwood galleries.

History and Development

Trail planning builds on layered histories: indigenous travel routes of the Sioux and Omaha (tribe) peoples, the Lewis and Clark Expedition, fur trade routes used by Meriwether Lewis and William Clark, steamboat commerce epitomized by the American Fur Company, and 19th-century expansion tied to the Oregon Trail and California Trail supply chains. Federal initiatives such as the establishment of the National Trails System Act and designation of the Lewis and Clark National Historic Trail provided frameworks for interpretive corridors, while river management projects under the U.S. Army Corps of Engineers reshaped floodplains through the Pick–Sloan Missouri Basin Program. Local civic projects in Sioux Falls, St. Joseph, Missouri, and Jefferson City, Missouri have created waterfront promenades that were later proposed as contiguous sections of the trail vision.

Recreational Use and Access

Recreational opportunities include long-distance paddling following historical steamboat channels, multi-day bicycle touring along levee roads, day hikes in the Missouri Breaks, and birdwatching in wetlands managed by the U.S. Fish and Wildlife Service. Access points cluster at trailheads near county recreation areas such as Oahe Recreation Area and municipal parks in Bismarck, North Dakota and Pierre, South Dakota. Organized events—paddle races inspired by Lewis and Clark bicentennial commemorations, community rides promoted by Rails-to-Trails Conservancy partners, and interpretive hikes with local historical societies such as the St. Louis Historical Society—increase public engagement. Seasonality influences use: spring high flows affect navigability near Fort Peck Lake while summer low flows concentrate paddlers and anglers around reservoirs.

Ecology and Environment

The corridor encompasses diverse ecoregions: headwater montane streams in Gallatin National Forest, Great Plains riparian corridors dominated by plains cottonwood and silver maple, and lower river oxbow wetlands that provide habitat for migratory birds on the Central Flyway. The trail intersects conservation priorities including habitat for species such as the Least tern, Piping plover, and riverine fishes like Pallid sturgeon. Hydrologic regulation by Gavins Point Dam and other Corps projects has influenced sediment transport, channel morphology, and seasonal floodplain inundation patterns, with downstream effects documented by agencies including the Environmental Protection Agency and U.S. Geological Survey. Restoration projects by entities such as the Natural Resources Conservation Service and local land trusts seek to reestablish native prairie, reconnect side channels, and control invasive plants such as Tamarix.

Cultural and Historical Significance

The river corridor is central to narratives of exploration, trade, and settlement involving Lewis and Clark Expedition, Sacajawea, steamboat entrepreneurs like Captain Grant Marsh, and military sites including Fort Union Trading Post National Historic Site. Archaeological sites and treaty locales tied to the Fort Laramie Treaty era reflect contested landscapes between tribal nations—including the Assiniboine and Mandan peoples—and the United States. Cultural tourism emphasizes interpretive centers at Fort Benton and museum collections at institutions like the National Frontier Trails Museum and Missouri History Museum, connecting audiences to themes in westward expansion and riverine commerce.

Management and Maintenance

Cooperative management involves multiple federal and state agencies: the National Park Service for interpretive routes, the U.S. Army Corps of Engineers for navigation and levee systems, state departments of natural resources in Montana through Missouri for parks and trails, and tribal governments for sites on sovereign lands. Nonprofit partners such as the Rails-to-Trails Conservancy, The Nature Conservancy, and local land trusts assist with trail construction, habitat restoration, and fundraising. Maintenance challenges include flood damage repair after major events cataloged by the National Weather Service, coordination across multi-jurisdictional levee districts, and balancing recreational access with protection of sensitive sites overseen by the Advisory Council on Historic Preservation.
