River Description

Our preferred put-in is at the Wisconsin Welcome Center, just upstream (South) of Hwy 2. (It's great to have heated changing rooms!)

On river, after about a mile of flatwater access, you'll find two significant falls. Peterson Falls (IV) is a rocky slide. Interstate Falls (V) (25') is runnable, but usually portaged. Between them is fairly continuous with few eddies. It is easy to pass the 'point of no return' above Interstate Falls, which has a tricky approach and (across much of its width) lands on shallow or exposed rock. Downstream of the falls, after a brief pause, you'll find nearly continuous rapids (possibly with many strainers) nearly all the way to the take-out.

Take-out is Nylund Road (A.K.A. Town Road 0028). (This was formerly labeled as Erickson Road, but I find no online indications of that name at present.)

Peterson Falls

Class - N/A Mile - 1.13
Rapid Thumbnail Missing

After nearly a mile of flatwater, you begin to encounter mild rocky rips. This is a sign that Peterson Falls lies just downstream.

Interstate Falls

Class - IV Mile - 1.53

At 1.4 miles, an island is encountered. Immediately at the end of this island lies the run-up to Interstate Falls. There is a house river-right at the falls -- please respect private property.


Gage Descriptions

Measure down from the downstream-river-left low steel beam on the bridge.

Minimum is about 7.5-8' down, and high-water is about 6' down.

Since comparing 'measure down' gauge readings can be confusing, I generally prefer to 'convert' them to positive readings thusly:
1) Measure down (as indicated above).
2) Subtract that reading from 8' (or 96") (the 'minimum' or 'zero' level for this run).
3) Record/report that as your gauge level.

Let's say you've run the river when the 'measure down' was 7'2" (or 86"). Subtracting that from 8' (96") gives you 10".
You arrive at the river and now and measure down to find the water 6'4" (76"), which converts to 1'8" (20").
Trying to compare the raw/measure-down readings of -7'2" (-86") versus -6'4" (76"), it is tough to know what to expect. However, comparing the converted readings, 10" versus 20", it is much easier to see the river is (I.E., will feel something very much like) twice as high!

Using this conversion, your 'recommended' levels are from 0" to 2' (I.E., 24"). As always levels above this may be run by people very experienced with this section, but are not likely to be preferred levels for those new to the run.
