River Description

Since we are using a pair of reference gauges, they will often disagree on runnability of this reach!
Ideally, you will want BOTH gauges 'showing green' and rising (or at least holding relatively steady) to 'confirm' runnability.
One gauge 'green' and the other 'yellow/orange' should tell you it's a crapshoot -- it could be too low, or it could be sweet -- you have to decide if you're willing to risk the drive.

Quick Facts:

Location: About midway between Manitowoc and Green Bay (~20 miles to each).
Shuttle Length: 4.3 mile. (See details in "Directions" Tab.)
Character: Fine rural trip has a mini-dells early on, and a couple short (6"-1') ledges, and a sweet series of waves/holes where the river slides down sloping bedrock just before the confluence with the Devils River.

Put-in is approximately 674' elevation.
Take-out is approximately 619' elevation.
Thus total elevation change is approximately 55'.

General Overview
A cute, small dells, and short bedrock ledges make a pleasant beginners paddle. This makes a great 'intro to whitewater' run, and is generally well suited for canoes and recreational kayaks. Be aware, however, that if you catch this at high water, the approach to the confluence with the Devil's River will push into class III (or III+) difficulty, and is VERY likely to swamp (capsize) your canoe or kayak. In fact, a couple of the holes will become very 'keepy'! Skirt them and it's a fun run, fail to skirt them and it's an almost certain 'yard sale' for all but the most experienced whitewater boaters!

Note: At the confluence with the Devil's River, the Nashota becomes the West Twin, one of the two rivers which give the town of Two Rivers its name. The "falls" marked on the topo maps on this reach are either non-existant, or so inconsequential as to be of no concern to all but the most inexperienced of boaters.

Also, while there is a 'falls' marked near a road on the East Twin (nearby), it appears to be on private property. There is little else apparent on that river in terms of gradient, so I strongly suspect it is a single minor ledge (on the order of a foot or so in height, probably much like the ledge at Nachtwey Road) with little else of whitewater merit on that branch, so I have not floated it. 

Alternate take-out is at Maribel Caves County Park. This eliminates about 1.1 miles of mostly flatwater and class I riffles, but requires a strenuous hike out, and is not readily identified from the river. I would highly recommend a visit to the park to hike the trails and find the caves, and drive past the ruins of the Maribel Hotel (a bit north of the park entrance on CTH.R).

Rapid Descriptions

USGS sampling site

Class - N/A Mile - -3
Rapid Thumbnail Missing

USGS lists a sampling site about 3 miles (crow-flies distance, not river distance) upstream of our listed put-in, citing drainage at that point as 43.1 square miles.

USGS sampling site

Class - N/A Mile - -1.8
Rapid Thumbnail Missing

USGS lists a sampling site on Black Creek about 1.8 miles (crow-flies distance, not river distance) upstream of our listed put-in, citing drainage at that point as 21.7 square miles.

Drainage area at our listed put-in is approximately 71.2 sq.mi. (as calculated via USGS StreamStats Beta software). By our listed take-out, it has increased to 114 square miles (60% increase).

Nachtwey Road 'falls'

Class - I Mile - 0.63

In Southeastern Wisconsin, it does not take much to be labeled a 'falls'. At this location, you will find a 1-2' ledge. At some flows, there may be some minor play possible here, but more likely, it will be little more than a short drop (or minor wave) to excite only those not much experienced in whitewater.

Just downstream of the bridge, a small dells will be encountered. At some flows, minor compression waves may form through here.


Class - I Mile - 0.7

Starting from under the Nachtwey Road bridge, rocky outcroppings first flank river-left, then (just a bit more downstream) river-right.

Hunter's Ledge

Class - II Mile - 1.26

A river-wide ledge precedes a left-hand bend in the river. At most water levels, almost anywhere (across its width) can be run. At some flows, there may be some whitewater 'play' possible here, and at some flows a few spots may become a bit 'keepy'.

Devils Meet Ledges

Class - II+ Mile - 1.36

As you round a bend, you head toward the confluence with the Devils River, where the Neshota River ceases to exist, and the combined flow becomes the West Twin. Before the confluence, the Neshota drops over a series of bedrock ledges and waves. At low flows, they are unlikely to cause much problem, and may offer tame possibilities for play. At moderate or higher flows there will be two holes that become rather 'keepy'. They can be skirted by staying far right. Scouting is advised (from river-left shore)! Be very aware as you walk, however, as there are random strands of barbed wire waiting to trip you or rip at your ankles.


Class - I Mile - 2.05
Rapid Thumbnail Missing

A house on river-left has a cement 'ford' in the river, to drive across at low flows. A suspension foot-bridge overhead allows the owners to park on river-left and cross over on foot at times of higher flows. For the boater, this cement 'ford' will cause a few ripples and waves, but should cause no hazard to boating.

Unfound Falls

Class - N/A Mile - 2.2
Rapid Thumbnail Missing

Most topographic maps have a 'falls' marked at this location. At all flows and all occasions which I have run this river, I have never been able to identify just what 'falls' they are talking about. There are a few spots which have some minor ripples and riffs, but do not expect (or worry about) any 'falls' on this part of the river.

At 266cfs every feature is runnable virtually anywhere and at a low Class 2 level. Excellent run for entry to the sport and for beginners. While the ability to roll is always preferred, lack of a roll should not be the reason to avoid this reach at this level.

Gage Descriptions

*The first (main) reference gauge is on the Kewaunee River, a very similar sized stream, 18 miles to the NorthNorthEast. We do not have sufficient experience with this river and gauge to have established reliable min/max. Minimum is an unconfirmed guess based solely on relatively similar whitewater rivers in the region. Maximum is only an indication of levels above which difficulty is likely to kick up a notch, specifically "Devil's Meet Ledges" may become keepy/playful holes.

*The secondary reference gauge is the Manitowoc River, 7.5 miles to the SouthSouthWest. While this is closer (than the Kewaunee), it is about four-times the drainage area, thus is likely to have different flow patterns. Again, we do not have sufficient experience with this river gauge to have established reliable min/max nor to 'test' the correlation.

Ideally, you will want both gauges to be high (or at least on-the-rise) to confirm the likelihood of good levels for this run.

We would appreciate if anyone running this reach would submit data (gauge/stage reading) and impressions (low/moderate/high) via the "Add a Comment" button on the "Comments" tab.

Visual inspection at Nachtwey Road of the ledge ("falls") and dells may also be used as a 'visual indicator'. If this ledge and dells looks boatable, the run should be good. If this ledge is completely covered (if there is no 'drop', only a wave), you have a fairly high flow, and should expect "Devil's Meet Ledges" to be pretty beefy!

Gauge/flow analysis for Kewaunee gauge (based on 44 years data) with reference to W.Twin gauge info (only 1 year of data, so very very limited value)
------------------------------ Kewaunee -------- West Twin
------------------------------(listed gauge) ----- (defunct gauge)
Drainage area at gauge ------127 sq.mi. -- 150 sq.mi.
All time minimum flow -------- 4.2 cfs --------- 11 cfs
90% of time flow exceeds --- 12 cfs ---------- 14 cfs
10% of time flow exceeds --162 cfs ---------130 cfs
All time maximum flow ---- 5950 cfs ------ 1240 cfs
10/90 ratio -----------------------13.5 -------------9.3 ('flashy-ness'; under 3 is fairly steady, over 10 is quite 'flashy')

Estimated average runnable days per year: 30
