The 59-mile reach stretches from about one mile below Gavins Point Dam to Nebraska's Ponca State Park. Flows on this reach are influenced by controlled releases from Gavins Point Dam. Check out river conditions before heading out.
Those who choose to paddle the Missouri River need to be well prepared for the adventure. Keep in mind the following:
- The Missouri is the deepest of the Nebraska rivers, 25 feet or more in some places.
- It is important that you wear a life jacket at all times. Only experienced paddlers should plan to be on the river.
- Quickly changing weather, long distances between launch sites, and the current can create major problems for novice paddlers.
- The water discharge rate can change hourly. The normal rate of flow is between 3 to 5 mph, while in periods of high water it can attain 7 mph or more.
- Be aware that the wind is an issue on most days, with prevailing winds out of the south and southwest.
The stretch between Gavins Point Dam and Yankton is the most developed. Downstream from Yankton the river has the taste of wildness to it that is nonexistent on the channelized river below Ponca State Park. The river is a series of meanders, chutes, and backwaters dominated by sandbars with an occasional heavily-timbered island. The river channel varies in width from a quarter to three quarters of a mile with an average width of a half mile. The depth of the channel or thalweg varies from ten to twenty feet. Side channels may be just inches deep while scours can create forty- to fifty-foot deep holes.
The floodplain varies in width from two miles at Gavins Point Dam to as much as twelve miles below the confluence with the James River. Grass- and farmland rise above the South Dakota side; the river often runs hard against high, wooded bluffs on the Nebraska side. The unique geology--orange and white chalk and gray shale--is often exposed where the river has carved away at the bluffs.
The river is dotted with sandbars, islands and backwater marshes that are havens for waterfowl, shore birds and other wildlife. Birders may want to stop and explore these areas, but they must remember that most of the land on the Nebraska side is privately owned and permission is required for access. On the South Dakota side, private property extends down to the mean high water level. In a few stretches the state borders are still indefinite.
Two bird species are of particular importance on the Missouri, the least tern and the piping plover. These shorebirds are on the federal Threatened and Endangered Species List and use the sandbars for nesting and raising young. These birds are protected under the Endangered Species Act, and it is unlawful to harass or disturb them. During the nesting season biologists post signs and use twine to delineate the nesting colonies. Please do not go into these areas when the birds are present.
River Mile Guide
Sites are listed below by River Mile (RM). River Miles are calculated as the distance on the Missouri above its confluence with the Mississippi River. Thus RM 0.0 is the confluence of the two rivers. Ponca State Park, NE, at RM 753.5, is 753.5 miles above the confluence.
Nebraska Tailwaters Boat Launch (River Mile 810.8)
You can begin your trip at the Nebraska Tailwaters Boat Launch, close to the campground (U.S. Army Corps of Engineers) on the Nebraska (south) side. There is another boat ramp known as the Training Dike (RM 810.1) across the river near the entrance to Chief White Crane Campground. Even though this boat ramp is on the other side, it is still in Nebraska.
About four miles down river you will pass Yankton (on the left) and then float under the new Discovery Bridge (US 81) and then the historic Meridian Bridge (presently closed to all access). Yankton is the "Mother City" of Dakota, having been settled in 1858. The bridge was designed for vehicular and railroad crossings--the upper level for cars and the lower level for trains. However, railroad track was never laid and the trains never ran. Built entirely with private funds, the Yankton community officially dedicated the bridge on October 11, 1924. The bridge was the last segment of a highway stretching from the Canadian border to Mexico. This highway is today also known as the Pan American Highway and extends some 17,000 miles down to the southern tip of South America.
Riverside Park Boat Launch (River Mile 805.4)
5.4 miles from Nebraska Tailwaters Boat Ramp is Yankton's Riverside Park Boat Launch. Modern restrooms are across the parking lot from the two-lane concrete ramp. This is a popular river access with recreational boaters. Downstream from here you will want to be especially alert for snags, sunken sandbars, and other hidden obstructions. To drive to this boat ramp from the Meridian Bridge take 2nd St. east to Pearl St. Turn right (south) and continue ahead to the river. Camping is not allowed here; however, primitive camping is allowed a couple hundred yards downstream (east of Marne Creek). There is no vehicle access to this primitive camping location. Vehicles can be parked at the trail head that is adjacent to the Yankton Chamber of Commerce office on SD 50 (east side of town).
Cedar County Park/St. Helena Boat Launch (River Mile 798.5)
It is 6.9 river miles from the Riverside Park Boat Ramp to the Cedar County Park and St. Helena Boat Launch, on the Nebraska side. A vault toilet and picnic shelter stand nearby, and primitive camping is allowed. Exercise caution when landing at this site due to the strong current along the bank. To drive to this boat ramp from Yankton go 1.0 mile south on US 81. Turn left (east) onto Road 898 and continue ahead for 7.0 miles. Turn left (north) onto Road 563 and proceed ahead 0.9 miles to the river. This route is all gravel after turning onto Road 898.
Or you can take Nebraska Highway 12 to Spur 14H (8.1 miles east of the intersection with US 81). Turn north onto the spur and continue 5.7 miles to St. Helena. Turn left at the store (9th St.) and go one block. Turn right onto Nette Rd. and go 0.3 miles. Turn left onto Jones and go 0.4 miles. Take the right fork in the road (573 Ave.) and continue ahead for 1.5 miles. Then take the left fork (Road 898) and proceed for 0.2 miles. Finally, turn right onto Road 563 and drive 0.9 miles to the river. St. Helena was an important steamboat port during the mid-19th century. However, during one of the "Big Muddy's" periodic floods, the river changed its course, cutting a new channel that left the town a couple miles from the river.
