Access plan
Access, shuttle, and map
Launch at Cotton Mill Park just below the Beaver Dam Lake dam and finish at the improved County Road J landing. This route has more gradient and small waves than most south-central Wisconsin paddles, so the live gauge, recent wood reports, and same-day dam behavior matter more than mileage.
Put-in
Cotton Mill ParkOpen mapCotton Mill Park is the clean public start, but the launch is close to the dam and the first small weir. Scout the first bridge/drop before committing.
Take-out
County Road J landingOpen mapCounty Road J now has a dedicated landing and parking area per recent Miles Paddled reports, but it is still road-adjacent. Do not block the nearby gate or private access.
Pulling access map tiles. Usually under 5 seconds.
Access caveats and watch for
Access caveats
- Cotton Mill Park is the clean public start, but the launch is close to the dam and the first small weir. Scout the first bridge/drop before committing.
- County Road J now has a dedicated landing and parking area per recent Miles Paddled reports, but it is still road-adjacent. Do not block the nearby gate or private access.
- A controlled release can make the route runnable, but abrupt dam-gate changes can also make the river rise quickly. Check the gauge shortly before launching and again at the put-in.
Watch for
- Class I-II waves, small weirs, and pushy downtown current, especially around Beaver Street, Center Street, Mill Street, and the Kraft corridor.
- Strainers and fresh wood between Davis Street and Cooper Street, around the Kraft corridor, and in the wooded middle reach.
- Low bridge clearance, blue-green algae warnings near the impoundment, wastewater-plant context, cold water, and wind on the slow marshy finish.

NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Official route supportBeaver Dam - 5.8 miles
Dodge County lists the Beaver Dam River as a county waterway route and describes the same downtown-to-Hwy-J trip character, ending where the rapids fade after Highway J.
- Direct gauge and reachUSGS 05425912 / 5.35 miles / Class I-II
American Whitewater lists Cotton Mill Park to CTH J as a 5.35-mile Class I-II reach using the Beaverdam River at Beaver Dam gauge.
- Primary app range30 to 140 cfs
Wisconsin River Trips treats 30-90 cfs as the great target band and 91-140 cfs as high-side but good if rapids are the priority; the app uses that combined 30-140 cfs as the guarded normal window.
- High-water ceiling211+ cfs too high for broad use
Wisconsin River Trips says strainers and fast current become annoying at 141-210 cfs and that 211+ cfs becomes obnoxious and partly dangerous; American Whitewater also warns not to exceed the recommended maximum because bridges can become difficult or impossible.
- Endpoint coordinatesCotton Mill Park 43.45456, -88.84298; County Road J 43.39397, -88.86828
Miles Paddled publishes GPS coordinates for Cotton Mill Park and the County Road J take-out, and its 2026 comment confirms a dedicated parking and landing area at County J.
