The Rock River is a larger watershed that starts in East Central Wisconsin and flows south into Illinois. This is mostly not a top-notch river for kayaking because of the slow current, but there are some stretches that can make for pleasant trips.
Lions Park to Elmwood Road
Date Paddled: September 2nd, 2017
Distance: 7.3 miles
Time: 3 hours 28 minutes
One of the better Lower Rock sections that starts really nice with a cool boulder garden. Unfortunately, that was the only major highlight as the rest of the trip was a bit too slow, muddy, and simple.Read More...
Hwy F to Hwy P
Date Paddled: October 29th, 2022
Distance: 6.0 miles
Time: Expect 3 hours
This was a trip with no interesting geology, almost no current, few rapids, and was honestly boring in spots. But despite all that, it turned out to be a surprisingly scenic, peaceful, and nice paddle.Read More...
- Upstream of Hillcrest Drive: I believe these portions are too congested to paddle.
- Hillcrest Drive to Hwy DW: 4.1 miles.
- Hillcrest Drive to Riveredge Park: 0.9 miles. Scenic stretch through the outskirts of Allenton with good clarity. However there are two major logjams to portage, and several minor logjams to squeak past.
- Riveredge Park to Hwy DW: 2.7 miles. An open stretch through wetgrass and a state natural area. One logjam needs to be portaged.
- Hwy DW to Hwy D: 5.5 miles. Outside of one nasty logjam cluster this is a pretty open creek paddle through a protected wildlife area that might be decent.
- Hwy D Wayside to N. Pole Rd. Launch: 7.3 miles. A good wetland paddle prospect through Theresa Marsh. Maybe 1-2 downed trees on the upper part.
- Kohlsville River: Note, the Kohlsville River joins the East Branch here, but it seems too congested with downed trees to be feasible.
- N. Pole Rd to Gill Rd(East): 6.0 miles.
- N. Pole Rd Landing to River Edge Park: 1.3 miles. Slow, open, and marshy channel. Nice though.
- River Edge Park to Rock River Street/Dam: 0.5 miles. A nice town paddle through the community of Theresa. One dam to portage.
- Rock River Street/Dam to Hwy AY: 3.5 miles. One of my favorite stretches on the entire Rock River. While shallow in spots, it is scenic with nice woods, small boulder gardens and multiple light rapids.
- Hwy AY to Gill Road(East): 0.7 miles. A brief wooded stretch that is a nice paddle.
- Gill Road(East) to Hwy 67/Dam: 8.3 miles.
- Gill Road(East) to McArthur Road/Fink Creek: 4.7 miles. Starts boring, weedy, and slow, but gets nice with clear water and rocks later on. Gill Road(West) may be a viable halfway access.
- McArthur Road to Hwy 67/Dam: 3.6 miles. A less interesting paddle through a flowage and downtown Mayville with numerous alt take-outs.
- Hwy 67 to Green Head Road Ramp: 6.4 miles.
- Hwy 67 to Hwy Y/Ziegler Park: 1.9 miles. One of the best paddling stretches on the entire Rock River with good current and small boulder gardens.
- Hwy Y to Hwy TW/Kekoskee Pond Ramp: 1.9 miles. A good stretch that includes a little bit of flowage paddling.
- Hwy TW to Green Head Road Ramp: 2.6 miles. An ok stretch as the river really slows and starts to turn into marsh.
- Green Head Road to N. Nebraska St. Ramp: 10.0 miles. The most popular route through Horicon Marsh known for its waterfowl.
- Upstream of E. Rock River Rd.: I suspect downed trees are too much of an issue for this to be navigable.
- E. Rock River Road to Hwy 49: 1.6 miles. Perhaps a cluster of downed trees in the middle and an electric fence upstream of Hwy 49.
- Hwy 49 to Waupun Park: 1.7 miles. Hwy 49 is not ideal for launching, but should be doable. A good prospect mostly through a golf course. Maybe 2 logjams?
- Waupun Park to E. Waupun Road: 7.2 miles. A good section.
- Waupun Park to Tanner Park: 3.1 miles. Great section though downtown Waupun. Alt access at Pine Street Park, Meadow View Park and Harris Mill Park.
- Tanner Park to Roadside Park: 3.2 miles. A pleasant paddle through a mixture of woods and open areas. A couple of logjam squeakers and one major portage.
- Roadside Park to E. Waupun Road: 0.9 miles. River widens, slows, and gets less interesting.
- E. Waupun Road to Dike Road: 10.0 miles. This is the northern unit of Horicon Marsh and is off limits to paddlers per National Wildlife Refuge rules.
- Dike Road to N. Nebraska St. Ramp: 5.6 miles. Am 80% sure you can drive on Dike Road from the east to launch in the ditch. Mostly a long straight canal paddle through Horicon Marsh with perhaps interesting side canals to explore. You can also launch in a west canal by Burnett Ditch Road. The city of Horicon marks the confluence of the South and East Branches of the Rock River.
It’s a neat prospect, but I suspect the logjam situation is too much (I could be wrong).
- N. Nebraska St. to Legion Park/Dam: 0.9 miles. An ok section through downtown Horicon.
- Legion Park to River Bend Park: 1.1 miles. Simple river segment…probably nothing too special.
- River Bend Park to Lions Park: 8.8 miles. A large and probably uninteresting flowage. If you get permission to take out at Ox-Bo Marine, you can avoid much of the flowage paddling.
- Lions Park to Elmwood Park: 7.2 miles. Trip starts nice with a great boulder garden, but becomes less interesting as the current dies.
- Elmwood Park to Hwy MM: 4.4 miles. An interesting prospect recommended by Frank Piraino.
- Hwy MM to Harnischfeger Park: 6.9 miles.
- Harnischfeger Park to Kaul Park/Hwy CW: 5.1 miles. Nice section with more wooded banks.
- Kaul Park to Kanow Park: 5.7 miles. Nice prospect.
- Kanow Park to Hwy F: 5.0 miles. Mediocre prospect.
- Hwy F to Hwy P: 6.0 miles. This isn't an elite trip with slow current and no exotic scenery. But it is pleasant and one of the nicer legs on the Lower Rock.
- Hwy P to Dam1st/Front St.: 5.6 miles. Probably an uninteresting flowage paddle.
- Dam1st/Front St. to Dam2nd/S. 1st Street: 2.6 miles. Possibly a unique paddle through downtown Watertown.
- 1st Street to Hwy 26 Launch: 3.5 miles. Mediocre prospect.
- Hwy 26 Launch to Hwy B: 10.9 miles. The put-in is SE of Hwy 26 via Jefferson Road. This segment is more undeveloped, but is still probably not interesting with the highlight being I94.
- Hwy B to Lubahn Park/N. Watertown Ave: 4.1 miles. Probably uninteresting.
- Lubahn Park to Tensfeldt Park: 2.3 miles. Paddling through downtown Jefferson might be unique, but there is a dam to portage. Many alt landings in Jefferson.
- Tensfeldt Park to Klement Park: 4.2 miles. Probably an interesting tweener section between Jefferson and Fort Atkinson.
- Klement Park to Lorman Bicentennial Park: 3.1 miles. A weak prospect through downtown Fort Atkinson.
- Lorman Park to Hwy 26 Ramp: 3.3 miles. A weak prospect.
- Hwy 26 to E. Knudsen Road Ramp: 11.8 miles. Mostly boring paddling on Lake Koshkonong. Many other launches on the lake.
- E. Knudsen Road Ramp to Hwy M/Dam: 3.4 miles. Boring flowage.
- Hwy M/Dam to Hwy 14: 8.2 miles. Probably uninteresting.
- Hwy 14 to Century Ave/Dam: 6.4 miles. A trip through downtown Janesville with several dangerous dams to portage (reviewed by AmericanWhitewater.org). There are also many other launch options in Janesville.
- Century Ave/Dam to Happy Hollow Park: 7.8 miles. A very industrial section.
- Happy Hollow Park to Preservation Park Boat launch: 3.2 miles.
- Preservation Park to Wooton Park Boat Ramp: 3.0 miles. Start of urban paddling in Beloit. Numerous other launch options in Beloit proper.
