Illinois river runs
Live streamflow, whitewater class, and length for every paddleable section in Illinois with a named USGS gauge. Built for kayakers, rafters, and canoeists.
Another favorite spot for whitewater enthusiasts in Illinois is the Fox River, specifically the segment between Yorkville and Dayton. This stretch offers Class I and II rapids, making it a great choice for beginners looking to gain some experience on the water. The Fox River is best tackled when the water levels are between 300-600 cubic feet per second. Safety is always a top priority when whitewater rafting or kayaking, so be sure to wear a properly fitted life jacket, helmet, and appropriate clothing. Always check the weather conditions and water levels before heading out, and never paddle alone. With the right precautions and a sense of adventure, Illinois can offer some thrilling whitewater experiences for any paddler. So grab your gear, hit the water, and make some unforgettable memories on the Illinois rivers!

About Illinois river runs
What does whitewater class mean?
The international whitewater scale (Class I–VI) rates a river's difficulty. I is moving water with riffles. II is straightforward rapids with clear channels. III requires complex maneuvers in fast water. IV is intense, powerful but predictable rapids requiring decisive boat handling. V is extremely long, obstructed, or violent rapids with significant hazard. VI is considered impossible to run.
Where does the Illinois streamflow data come from?
USGS streamgauges. Each Illinois paddle run is keyed to a specific gauge that paddlers and outfitters have agreed represents flow on that section. Gauges report every 15 minutes; we re-pull throughout the day.
What's a runnable level?
Run-specific. A creek that's classic at 200 cfs might be too low at 100 and dangerously flooded at 1,000. Always cross-reference with a guidebook or a Illinois paddling club for the run's accepted gauge ranges before launching.
Can I get an alert when a run hits prime flow?
Yes. Save any paddle run as a favorite in the Snoflo iOS app, set a flow window (e.g. "alert me between 800 and 1,500 cfs"), and you'll get a push the moment it crosses into range. Free with a Snoflo account.
Is this a substitute for local guidebooks and trip leaders?
No. Snoflo is informational. Always carry appropriate skills, gear, and a sober assessment of the day's flow. For high-consequence runs (Class IV+), paddle with people who know the run and never solo. American Whitewater is the authoritative source for U.S. river information.
