Koshkonong Wildlife Area

Koshkonong Wildlife Area is a property of approximately 800 acres consisting of a high quality deep water marsh which transitions into shrub carr and bottomland hardwoods. On the south side of the property there is a small portion of uplands primarily consisting of existing and restored oak savanna.

To find Koshkonong Wildlife Area, go south of Fort Atkinson on US 26 and watch for access to OLD 26 on the west side of the highway. Head south on OLD 26 to Mounds Road, turn west and the southern most parking lot is immediately on the right or north side.

The Rock River can be accessed by a boat launch to the north east off the west end of Groeller Road. On the west side of Koshkonong Wildlife Area, Lake Koshkonong can be accessed by a boat launch located at the north end of Vinnie Haha Road off of Mounds Road.


Koshkonong Wildlife Area started as a scattered wetland purchased with the protection of the high quality wetland adjacent to the lake being the primary concern. In 1990 the decision was made to make the area into full Wildlife Area Project which would provide the opportunity to increase acquisition of adjacent lands. This action provides an improvement of hunting and wildlife watching opportunities and better protects the wetlands.

Today, habitat management objectives are to further protect the wetlands and restore other native habitat types including some oak savanna. Methods to meet these objectives include prescribed burning, planting, removal of invasive species. For a complete list of resource management, development, and protection objectives, as well as public use management and development objectives.

The Glacial Heritage Area master plan was completed in 2011 and guides the long term management of this property. Progress toward achieving the goals of the master plan are tracked through annual monitoring reports.
