Pecatonica River – East Branch – Blanchardville
Date Paddled: September 18th, 2021
Put-in: Blanchardville Dam
Take-out: Hwy 78
Distance: 3.8 miles
Time: Expect 2 hours
Water Level: East Branch of the Pecatonica @ Blanchardville 123 CFS or 4.38'
The Pecatonica River is the largest river in far Southwestern Wisconsin and is split into two main branches. The East Branch is a bit smaller, but much of its length is good for paddling. My favorite parts are its upper stretches. Previous trips (Hollandale, the Dodge Branch, and Gordon Creek) were generally positive experiences. With water levels being a bit low this year, I decided to explore more of the lower stretches, starting with Blanchardville. Fun side fact…Blanchardville was founded by Mormons and was originally called Zarahelma. Personally I like the old name better.
There are actually multiple ways to start a trip in town, but I chose to launch below the dam which was scenic. After getting into the water, I was surprised to encounter Class 1 Rapids, but these didn’t last long and soon the river would slow to a crawl…and remain that way for most of the trip. The outskirts of Blanchardville weren’t bad with the highlight being a nice pedestrian bridge to paddle under. Things in town that day were hopping as a parade was about to start…had I started my trip a bit later, I wouldn’t have been able to park where I did.
I soon passed the Gordon Creek inlet, where a nice public boat ramp is located at the mouth. The much clearer water of Gordon Creek brought back memories of my previous trip, and made for a stark contrast to the turbid Pecatonica. I headed upstream on the creek to the Hwy H bridge where I was quickly dead-ended by a large logjam (which also brought back memories of Gordon Creek).
The river for the first mile had a nice open vibe to it. The banks weren’t exclusively cornfields (which is what you would expect) and in some spots there were what looked like original prairie plants. It also appeared artificial bank work had been done to channelize the river. Part of this might have been to help prevent flooding. A few years ago, Blanchardville endured massive flooding that turned the local area into a lake.
As the river turned south though, the river became much less interesting. Some of the rare highlights included an owl I chased downstream, and some exotic mushrooms that were fun to photograph. That was it for excitement, as the river really lacked defining attributes (rapids, hills, bluffs, outcrops). Granted, it wasn’t bad and I did appreciate that there were no major obstacles or logjams to deal with.
The river made a final turn west, which paralleled the only hill of the trip, but still no outcrops. I ended the trip at Hwy 78, which honestly was a bad bridge access (steep, weedy, & deep water).
In summary this was a ho-hum trip that likely deserved its two star rating. If you’re a local I definitely recommend checking it out, but for everybody else there are better nearby prospects to do. The Hollandale section or the Hwy 78 to River Road section would be recommended trips for first-time East Branchers. Relief maps suggest many outcrops below 78 (where I took out) and that’s likely what I should have paddled instead. A trip for another day…
Sights included a few painted turtles and a muskrat. The highlight was an owl that I was able to get relatively close to.
Blanchardville Dam: There appears to be a semi-public mini-park north of the dam where one could launch. However there are rapids and large boulders along the north bank. What I did instead was launch from the south shore behind the history museum where there is better parking and a nice sandy area under the bridge for launching.
- Horseshoe Bend Rd (3.6 miles upstream from the dam). This is an ok bridge access that is frequently used by paddlers. Between here and the dam is a mediocre stretch that isn’t super special.
- Gordon Creek Boat Ramp (0.3 miles downstream from the dam). This is a very good public access. Most paddlers will prefer to launch here instead of by the dam (where I started only for pictures).
Hwy 78: This was a bad bridge access. The banks were steep and weedy, and the channel was deep by the bridge so there wasn’t a great take-out spot. There is an adjacent drive that looks like it would be a better access and I suspect paddlers use it, but there was no evidence that it was public, so I stuck to the main road.
- River Road (6.1 miles downstream from Hwy 78). This should be an ok bridge access. This six mile stretch is a good prospect and relief maps suggest many good rock formations.
Bike Shuttle Route – Hwy 78 to Blanchardville Dam: 2.0 miles with 75′ of ascent. This is a short shuttle route, but much of it is up a long hill and next to fast traffic. All in all, not bad though.
Hazards, Logjams and Current:
Current: The current is generally fairly slow, but may pick up speed when high.
Hazards: None really…there are no logjams, fences, cows or any other problems.
River Depth and Navigability:
Trip done at 123 CFS per a local gauge at Blanchardville.
- 0-100 CFS: A low depth, but should be fine for paddling.
- 101-200 CFS: An average depth and a good target range.
- 201-300 CFS: Above average, but a decent paddling depth.
- 301-400 CFS: A high depth.
- 401-600 CFS: A very high depth. Current may be pushy in spots.
- 601+ CFS: Maybe too high for enjoyable paddling.
- Upstream of Hwy Hk: Too many logjams to recommend.
- Hwy Hk to Burma Road: 1.3 miles. An ok prospect with perhaps some obstructions.
- Burma Road to Star Valley Road1st: 2.0 miles. An interesting prospect with good scenery and not too many logjams.
- Star Valley Road1st to Hwy 39: 3.1 miles. Good scenery potential but too congested.
- Hwy 39 to Horseshoe Bend Road: 7.6 miles.
- Hwy 39 to McKenna Road: 3.9 miles. A pleasant section with a rock outcrop near the take-out.
- McKenna Road to Horseshoe Bend Road: 3.7 miles. Another pleasant section with a massive rock wall.
- Horseshoe Bend to Blanchardville Dam: 3.6 miles. Less interesting prospect compared to the immediate upstream section. This part of the river has seen tornado damage, but this should be mostly cleared up now.
- Blanchardville Dam to Hwy 78: 3.9 miles.
- Blanchardville Dam to Gordon Creek Landing: 0.3 miles. A short, but pleasant stretch through the outskirts of Blanchardville.
- Gordon Creek Landing to Hwy 78: 3.5 miles. While not bad, this is one of the lesser interesting stretches.
- Hwy 78 to River Road: 6.4 miles. A good prospect with several nice outcrops.
- River Road to Argyle Boat Launch: 7.4 miles. Also a good prospect with more outcrops. Alternative take-out at River Street.
- Argyle Boat Launch to Blackhawk Memorial Park: 8.3 miles. Not as nice as previous sections but still good.
- Blackhawk Memorial Park to Road M: 1.0 miles.
- Hwy M to Cisserville Road: 6.4 miles. Probably uninteresting.
- Cisserville Road to Mouth: 2.2 miles. Probably a weak prospect.
- Mouth to Hwy 11: 3.2 miles. A leg on the Pecatonica River (main branch) to reach a take-out.
