Description

This hydraulic jump (cement ledge/pourover) used to be ~66 inches (at the metal-capped shoulders). Some years back (when they removed cement channelization of the half-mile upstream) they redid the approach and the lip, lowering the center to a 30 inch drop.

Remediation (done during 2017) removed concrete channel from here down to nearly the confluence with the Menomonee River. While a short segment of cement channel remains (to preserve and protect the footing for the railroad trestle), the effective drop is now almost completely gone; Quarried rock fills much of the area downstream of the trestle and backwaters a pool which generally eliminates the hydraulic jump. So, while there may be some wave/hole at some optimal flows, be aware that massive rocks lie just under the surface, limiting advisability of any play here.
