Gauge Information

Gauge Description:

*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!
