Lake Koshkonong Dredging and Cooperation with Town of Koshkonong

Kim-

As we discussed, we would like to brief the Town Board at their meeting scheduled for Jan 9 on the Lake Koshkonong Dredging and Shoreline Restoration Project, located in the Town of Sumner, and to understand the agreements that would be required by the Town of Koshkonong for use of North Shore Road from the Sumner boundary to STH 106 for construction equipment and materials transport.  We understand that North Shore Road has been designated by the Town as a 12 ton road. 

This project is being constructed by the Rock Koshkonong Lake District, supported by cost share funding from the Wisconsin Department of Natural Resources.   Montgomery Associates is the design engineer for the project, working for the Lake District.  The project includes dredging at the North Shore Launch Ramp and fill to create wetlands further south, all within the Town of Sumner.  Our project is currently out to bid, with bids due back on Jan 9.  The heavy construction work is anticipated to be completed in January and February of 2013. 

The project is intended to provide a "win-win" approach to navigational access dredging on the shallow shorelines of Lake Koshkonong, with use of the dredge spoil material to replace areas of lost wetland on adjacent shorelines. In this case, we are dredging approximately 3500 yd.³ of sediment at the North Shore boat launch ramp and placing it to provide additional shoreline protection at the entrance of Mud Lake to Lake Koshkonong. We have an agreement with the Twin Island Gun Club, which owns the property adjacent to Mud Lake for construction of this project.
