Boating in the MNRR
The Missouri National Recreational River offers scenic views and a variety of river opportunities for all boaters. The depth of the river varies considerably, from a few inches to ten and twelve feet, with a few holes up to forty feet. The less water your boat drafts, the easier it will be to navigate. Keep in mind that the channel is not marked and that it can shift from week to week, that there are sunken sandbars, snags and sawyers, and other hidden obstacles.
The use of personal watercraft, commonly known as jet skis, is prohibited within the Missouri National Recreational River. They are allowed on the large reservoirs behind the dams and on the river below Ponca State Park.
The lower 20 miles of the Niobrara River can normally only be navigated by canoes or kayaks. Reading the river is a must as in some places the (unmarked) channel is very narrow; otherwise, the canoeist will at times and in places have to get out and lift or push the canoe/kayak.
General Rules: An accessible, U.S. Coast Guard-approved wearable personal flotation device is required for each person on board. The State of Nebraska requires a child under 13 to wear a U.S. Coast Guard-approved life preserver while aboard any vessel.
Non-motorized craft, i.e., canoes and sailboats, have the right-of-way.
Waterskiing is forbidden from one-half hour after sunset to one-half hour before sunrise.
Camping: Primitive camping is normally allowed on islands and sandbars. Please adhere to the "pack-it-in, pack-it-out" (Leave No Trace) ethic. On the Nebraska side of the channel, the adjacent landowner owns all the land up to the center of the channel. This includes islands, bottomlands and even the riverbed. On the South Dakota side of the channel, the landowner owns up to the mean high water level. In several locations along the river, the state border is still undetermined.
Reminders: Water levels vary due to weather and releases from the Gavins Point and Fort Randall dams. Releases from the latter are unpredictable and often increase at night. Click on releases to find out about river levels and other data.
One of the dangers of boating on the Missouri is missing the main channel and going aground in the shallows. A sure sign of a shallow area is water rippling. The current passing over a barely submerged area causes this effect. Another way to avoid shallow water is to look for changes in the color of the water. Water that has a light brownish color compared to a deeper blue color of nearby water is a sign of a submerged sandbar.
Snags should be avoided for the danger they present and the potential they pose for damage if struck by a boat. A particularly dangerous type of snag is the "widowmaker." This is a snag that is barely below the surface of the water. It can be seen as a V-shaped ripple of water. Some parts of the park are noticeably filled with snags. This is particularly true at North Alabama Bend to Mulberry Bend (river mile 779 to river mile 776). This and other areas filled with snags should be approached with caution and steered through slowly.
There are no marinas or on-the-water gas services in the park. The closest ones are in Sioux City, Iowa, and on Lewis and Clark Lake (west of Gavins Point Dam).
Missouri River Mileage: River mileage begins at the mouth of the Missouri just north of St. Louis, MO. From river mile 0 to 752 (near Ponca State Park, NE), the river is channelized for barge navigation. Two "natural" river segments comprise the Missouri National Recreational River. These reaches are located at: 59 miles between Ponca, NE, (river mile 752) and Gavins Point Dam (river mile 811) and 40 miles between Running Water, SD, (river mile 840) and Fort Randall Dam (river mile 880).
A long, shallow and braided delta exists at the upstream end (headwaters) of Lewis and Clark Lake behind Gavins Point Dam. Also, the Niobrara River has formed a delta in the Missouri River on the upstream side of the headwaters. Extent of both deltas are from river mile 827 to river mile 847.
