Rock, E.Br. - (Theresa to) Kekoskee (PnP, or unlikely run up to 13 miles) (WI)
Approximate - nearest available gauge. Use as general reference only.
A dam on N.Main Street (State Highway 67+28) in Mayville has releasable gates (to the right 1/3rd) ramping short and spilling off high to fall onto shallow splashpan. The river-left (2/3rds) of the dam ramps steeply down to the splashpan. Water sheets across about 12 yards before encountering slightly deeper riverbottom.
It is remotely possible that (at some finite flows) there may be some whitewater play in currents in this area. A park on river-right allows parking and access, though the shore at the dam is steep quarried rock. Any location convenient to launch from may make attainment (of any playable feature which might occur here) a bit difficult. Much of the area is shallow, making scrapey conditions for good paddle strokes.
Downstream (from here to the Kekoskee Dam) appears as though it may have some areas of minor shoals, riffles and rips ... at least at some flows. There is 1 mile at 20 FPM, then a mile at 10 FPM, before things peter out into the backwaters of the Kekoskee dam.
