The problem was that the earth on the west side of the weir started to erode creating a by-pass channel, which then widened and caused the barrier to shift.
The permanent fix? The construction of a rock arch rapids, which was set to be built this spring. The project was pushed up and work began on Wednesday, March 3. Funding for it was provided by the Midwest Glacial Lakes Partnership and Outdoor Heritage Fund, created as part of the Clean Water, Land and Legacy Amendment, according to Amanda Hillman, restoration coordinator with the DNR s River Ecology Unit.
Hillman said the construction will take about a month to complete, depending on weather and site conditions.
