The 4th Avenue access site in Camanche provides a public boat ramp on the Mississippi River, one of North America's major waterways. Located at river mile 2334 from the Gulf of Mexico, this site serves as a convenient launch point for kayakers, canoeists, and motorboaters exploring this section of the Upper Mississippi. The river here is a substantial waterway with significant current—averaging 11.24 feet per second—and high volume flow (averaging over 685,000 cubic feet per second), so paddlers should be prepared for strong, steady currents and plan accordingly.
The Mississippi at this location is a mature, powerful river (classified as Stream Order 10) with a gentle overall gradient of 0.8 feet per mile. Paddlers should expect variable conditions depending on water levels and seasonal flows. This access point is located in Clinton County near the Camanche area. For current information about ramp conditions, hours of operation, facilities, and any fees, contact local Clinton County or Scott County Parks departments at 563-328-3281 or 563-328-3282.
