Allen Park in Ottawa offers four public boat launching ramps providing convenient access to the Illinois River. Developed in 1959, this established facility is located within the Illinois and Michigan Canal National Heritage Corridor and supports a variety of water activities including boating, fishing, and paddling. The park offers both paid and free parking options, with restroom facilities and drinking water available.
The Illinois River at this location is a major waterway (Stream Order 9) with significant flow averaging over 27,000 cubic feet per second and typical velocities around 4.3 feet per second. Paddlers should be prepared for a substantial river with moderate current. The river maintains a gentle average gradient of 0.3 feet per mile through this region, making it generally suitable for various skill levels, though water conditions can vary seasonally. The broad drainage area of 27,507 square miles means this section of the Illinois River responds significantly to upstream weather and water management activities.
Allen Park's multiple launch ramps make it an accessible put-in point for day trips, longer paddles, or motorized boating on this 273-mile river system.
