Rock River – South Branch
Date Paddled: May 9th, 2015
Put-in: Waupun Park
Take-out: E. Waupun Road Access
Distance: 7.31 Miles
Time: 4 hours 18 minutes
Gradient: 3.2' per mile (guestimate)
Water Level: South Branch Rock River @ Waupun 2.36' or 29 CFS
Another “roll-of-the-dice” paddle that turned out pretty good. The South Branch of the Rock River is one of three branches that form Horicon Marsh. This trip is maybe half urban paddle (quite nice), half hardwood paddle (ok), and finally a little marsh before you legally have to get off the water.
Waupun Park (located on the west end of the city of Waupun) is a great put-in with public parking, nice launching area and outhouses.
Ok take-out at the end of E. Waupun Road. It’s a dead-end road with a small strip of publicly owned land leading to the water. It’s hidey, but there is a trail leading to the river. Tad mucky for taking out, but doable.
Relatively easy bike shuttle at 5.2 miles with no major hills. Lot of city biking in Waupun, but it is easy to avoid traffic by biking on the side streets.
Hazards and Log Jams:
The main dam in Waupun is easy to portage. Just prior to Fond du Lac Street there appears to be the remnants of an old dam and a very small ledge that creates a bit of a backroller. You should be ok as it is so small, but you can portage it if in doubt.
The town section is remarkably free of log jams (it gets cleaned out). However, after the city there are a couple of hoppers and duckers to contend with. I only had to portage once, which was not fun but is doable (this spot is pictured/youtubed/mapped for reference to any log jam clearing angels out there).
River Depth, Navigability and Current:
Do you want clarity or padding for riffles? I went at 29 CFS (typical average) which provided mostly adequate padding for light rapids, but did somewhat obscure the water clarity I had scouted a month earlier (that was 13 CFS). 20 CFS might be a nice target flow rate as a compromise so you can see the attractive rocky bottom of the river. Nice thing about 29 CFS though was that it allowed me to get over some low log jams that I might otherwise not have.
The current is stop and start…and not just because of the dam and small flowage in town. Sometimes it will hardly move (typical Rock River) then will surprise you with a riffle (very atypical Rock River). Most of the riffles are in town, but there are a couple on the eastern leg of the trip (in the “big woods”).
Substrate and Water Quality:
Kind of muddy but really mostly rocky. Again a surprise for the Rock River as you usually don’t associate rocks with it (despite its name).
Ducks, geese (+lots of goslings), carp, great blue herons, deer, pelicans (by the marsh) dragonflies, a bronze horse and evidence of beavers. Award for most prolific animal would go to the painted turtle…saw lots.
First half of the trip is an urban paddle, but this is not too distracting as the river is mostly flanked by a nice buffer of trees.
There are a number of class 1 rapids (well riffles) on the trip and the first will be by an obscure park on Pine Street. Fun to run, but be mindful of the low pedestrian bridge you’ll need to duck under. The river following Pine Street was my favorite section. Relatively clean banks, nice tree canopies and occasional light rapids.
Following the Hwy MM bridge, the river slows down and gets big (and boring). The flowage created by the dam isn’t too long, but is still unfortunate. The dam itself is easy to portage with readily visible portage signs.
There is a park at the dam which is kind of scenic. Below the dam the rocks have been washed clean, leaving a very attractive boulder garden. The park is famous for the “End of the Trail” sculpture (basically a very depressed Indian on an equally depressed horse). I tried to run the rapids almost directly below the dam, but it was too bumpy and I can’t recommend this for others at 30 CFS (much easier to put in below the rapids too).
River stays nice after that, but then the character kind of changes by the Hwy 151 bridge and the sanitation plant. Most sanitation facilities actually don’t have an odor, but this did unfortunately and nutrient growth in the water really picked up after that (and occasional scum would start to accrue by down trees). Hwy 151 is of course very noisy and you could hear it for maybe a mile from the bridge. I don’t want to sell short the section after Hwy 151 as it was nice, but some paddlers might want to cut the trip in half here at maybe 3.5 miles.
From Hwy 151, the trip leaves Waupun behind and starts first as an open farm field paddle (pleasant but not exotic) and then continues from there as mostly a hardwood paddle that kind of reminded me of the Baraboo River. A nice peaceful woodland paddle, with attractive tree canopies and the occasional riffle. But not as “clean” concerning substrate, water quality and the amount of deadwood in the paddle. All that being said though, I only had to portage once which is impressive for any woodland paddle.
At the end of the woods, the West Branch of the Rock River (a future prospect) joins the South Branch and significantly changes the character of the river (mostly bigger and more boring). Soon after the confluence, you’ll shoot over some light rapids and come to Roadside Park, which would be a great take-out location.
Instead, I paddled another half-mile and experienced classic Rock. Wide, straight, muddy, and boring. Take-out will be shortly after the Wild Goose Trail bridge (a fine bike trail that I do recommend exploring). Why take out here? Well, the signs on the water will make that abundantly clear. While there are a number of paddle-friendly Rock River Water Trail signs throughout the trip (including on the bike bridge), by the take-out there are multiple signs that signify this is the start of the Horicon National Wildlife Refuge. Unlike the south half of Horicon Marsh, which is state controlled, the north half is run by the Feds and has much stricter access rules (which includes no kayaking in the refuge). Shucks.
If you’ve driven this far to do the East Branch, you might as well check out the marsh after the trip. Best ways of doing this?
My first suggestion would be take the “car tour” loop located at the north end of the marsh off of Hwy 49. This has a very “national park” feel to it…complete with the small one lane road, pull-offs for viewing and information kiosks, nature trails and of course lots of people. But instead of cars backing up the roads to take pictures of bison, you get backed up cars for photos of goslings (and their hissing, protective parents) as well as pelicans and a number of other birds you can see from the car loop. The best and most popular part of the car loop is an aquatic boardwalk and trail that runs a mile and lets you optimally experience the marsh with expansive views of the marsh, birds and even the wind generators in the background (which I’m sure the birds find scenic).
Maybe the next best way to experience the marsh is by bike. The Wild Goose Trail is a great way to do this but only comes close to the marsh for 4-5 miles before continuing on to Fond du Lac. The trails off of Dike Road and Old Marsh Road look the most interesting, but I think they’re only open in the summer. Here is a nice comprehensive bike map of the marsh.
The visitor center on the east side of the marsh is well done with an attractive overlook.
Best way to see the big picture is to drive up (literally) to Ledge Park which has a nice vista of the park.
Oh…and you could of course paddle the marsh (at least the south end).
Other Rock River Trips:
- Upstream of E. Rock River Rd.: I suspect downed trees are too much of an issue to be navigable.
- E. Rock River R. 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 log jams?
- 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 (reviewed May 2015).
- Tanner Park to Roadside Park: 3.2 miles. Pleasant paddle through a mixture of woods and open areas. Couple of log jam squeakers and one major portage (reviewed May 2015).
- Roadside Park to E. Waupun Road: 0.9 miles. River widens, slows, and gets less interesting (reviewed May 2015).
- 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 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.
- Upstream of Hillcrest Drive: I believe these portions are too congested to paddle.
- Hillcrest Drive to Rock River Drive: 0.9 miles. A pleasant prospect though Allenton.
- Rock River Drive to Hwy DW: 2.9 miles. Mostly open, but maybe 3-5 serious downed trees.
- Hwy DW to Hwy D: 5.5 miles. Outside of one nasty log jam cluster this is a pretty open creek paddle through a protected wildlife area that might be decent.
- Hwy D Wayside 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 Mill Street Ramp: 1.4 miles. Slow open channel.
- Mill Street to McArthur Road/Sewage Plant: 1.0 miles. Good prospect through downtown Theresa. Multiple alt access points, and one dam to portage.
- Sewage Plant to Hwy AY: 2.8 miles. A good prospect with some rocky and riffly areas, but I believe some downed trees (maybe 0-4).
- Hwy AY to Gill Road(1st): 0.7 miles. An ok prospect with wooded banks and maybe one downed tree.
- Gill Road(1st) to McArthur Road/Fink Creek: 4.7 miles. Starts boring, weedy, and slow, but gets nice with clear water and rocks later on (reviewed Aug 2014).
- McArthur Road to Hwy 67/Dam: 3.6 miles. A less interesting paddle through a flowage and downtown Mayville with numerous alt take-outs (reviewed Aug 2014).
- Hwy 67 to Hwy Y/Ziegler Park: 1.9 miles. Probably the best paddling stretch on the entire Rock River with good current and small boulder gardens (reviewed Jun 2015).
- Hwy Y to Hwy TW/Kekoskee Pond Ramp: 1.9 miles. A good stetch that includes a little bit of flowage paddling (reviewed Jun 2015).
- Hwy TW to Green Head Road Ramp: 2.6 miles. An ok stretch as the river really slows and starts to turn into the marsh (reviewed Jun 2015).
- Green Head Road to N. Nebraska St. Ramp: 10.0 miles. The most popular route through Horicon Marsh known for its waterfowl (reviewed Jun 2012).
It’s a neat prospect, but I suspect the log jam situation is too much (I could be wrong).
- N. Nebraska St. to Legion Park/Dam: 0.9 miles. An ok section through downtown Horicon (reviewed Jun 2012).
- 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. Good prospect and mostly undeveloped. Recommended by Frank Piraino.
- Elmwood Park to Hwy MM: 4.4 miles. Good 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. Mediocre prospect.
- Hwy P to Dam1st/Front St.: 5.6 miles. Probably an interesting 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 Centur 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.
- Centur 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.
