Fox (Illinois R. trib.) - B) Waterford/Rochester/Burlington (PnP) (WI)
Approximate - nearest available gauge. Use as general reference only.
The left-channel (in Waterford, around a large island filled with condos) has a uniform-lip cement wall/dam, from which water spills into a shallow, rocky outflow. Since pool height is regulated by the main dam (in the other channel), there would rarely (if ever) be enough flow here to cover the considerable amount of shallow rock to allow any chance at passage (or any sort of play) in any paddle-craft.
(NOTE: subsequent to this photo, the rocks have been pushed up closer to the base of the dam.)
