Streambank/Shoreline Protection Projects


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 small shoreline protection project was completed on the south shore of Lake Poygan in 2003.

Lone Willow Island

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.

Harold Eichstadt

This 254-foot project was completed to protect a small wooded wetland area. Some rock was already present on the shoreline, but it was insufficient to prevent large waves from overtopping. Additional rock was placed on the shoreline to provide the proper amount of protection.

Bohn Farms

This 1,200 foot shoreline protection project was installed in the winter of 2003 on the south shore of Lake Poygan.  A number of large trees had been uprooted by waves and ice shoves and a significant amount of soil had been lost.  Rock riprap was placed on the shore to protect it.
