This large rock structure was installed on the west side of Lake Butte des Morts in February of 2003. The rock structure spans nearly 2,800 feet in total length and involves 3 different property owners. The intent of this project is to protect the remaining marsh from further damage and to create a quiet area for plants to regenerate.
This large wetland complex on Lake Poygan was protected by a rock breakwall many years ago. Over time, the rock breakwall subsided into the bottom sediment and waves began to overtop the structure. Hundreds of acres of marsh were eroded away as waves were able to reach the vulnerable shoreline.
