Upper Mississippi Conservation Area

Oneill Creek provides boat ramp access to the Mississippi River near Clarksville in Pike County. This location offers convenient launching for kayakers, canoeists, and motorboaters looking to access one of North America's major waterways. The site is positioned along the lower Mississippi River, which maintains a substantial average flow of approximately 685,000 cubic feet per second and travels at an average velocity of 11.24 feet per second—conditions typical for this major river system.

Paddlers should be prepared for the strong current and significant water volume characteristic of the Mississippi River at this location. The river's average velocity and steady gradient mean that water conditions can change rapidly, particularly during high-water periods. The nearby Clarence Cannon National Wildlife Refuge offers additional recreation opportunities in the area. Before launching, check current water conditions and be aware that nearby access points like the Truman Access ramp have experienced closures due to flood damage, so verify that Oneill Creek is operational before your trip.
