Pike (Kenosha Co.) - Petrifying Springs to Lathrop & CTH.A (up to 4.5 miles) (WI)
Too low for whitewater. May be floated, but will be 'grungy'.
As the river swings by the clubhouse, and the shores turn to vertical steel plate armament, cement rubble in the stream creates a small wave. This can offer some tame surfs at moderate flows (though I'd be real hesitant about doing anything that might have one upside-down or out of boat, due to the concrete rubble you'll likely encounter).
