Erosion Control: Rip Rap

In Fall 2012, the Wonder Lake Master Property Owners Association (MPOA) completed an important element of our overall lake restoration project. This work included the placement of supplemental limestone rip-rap on the upstream face of the Wonder Lake dam embankment, and the installation of rip-rap “collars” around three island areas in the southeast quadrant of the lake.

Wonder Lake Annual Dam Inspection Report

 

Each year the MPOA is required by the State of Illinois - Office of Water Resources to have an inspection of the Wonder Lake Dam embankment and spillway. This inspection is conducted by Professional Engineers retained by the MPOA, with state engineers also in attendance. The completed report is then forwarded to the Illinois Office of Water Resources.
