Mendenhall Park in Bartonville offers convenient public access to the Illinois River with four boat launching ramps suitable for kayaks, canoes, and motorboats. Originally developed in 1959, the park provides a solid put-in point for paddlers looking to explore this major river system.
The Illinois River at this location is a substantial waterway—a major river (Stream Order 9) with an average flow of over 27,000 cubic feet per second and moderate current averaging 4.3 feet per second. With a gentle gradient of 0.3 feet per mile, this section is generally manageable for intermediate paddlers, though the strong flow and size of the river should be respected. The river extends 273 miles total with relatively modest elevation change, making it suitable for extended multi-day paddling trips.
Before launching, paddlers should be prepared for river current and consider water conditions, as flow can vary seasonally. The park's multiple ramps make it a practical access point for both day trips and longer expeditions on this significant Illinois waterway.
