The Illinois River at this location is a substantial waterway—a major stream order 9 river with an average flow of over 27,000 cubic feet per second and current velocities around 4.3 feet per second. Paddlers and boaters should be prepared for moderate current and the typical conditions of a large, flowing river system. With 273+ miles of navigable water and a gentle average gradient of 0.3 feet per mile, the Illinois River offers relatively stable paddling and boating conditions, making this a good launching point for both day trips and longer river explorations in the region.
