Grundman Boat Landing is currently under construction and will be closed from July 5 until the end of the year. The timeline for this project is subject to change. During this time samples will not be collected and E. Coli testing will not be done.
Bacteria levels can change quickly depending on waves and wind. Always take a look at water conditions before you enter the water and avoid contact with algae blooms.
Grundman Boat Landing
1801 Grundman Ln, Oshkosh
The Grundman Park Boat Launch is located on the west side of Lake Winnebago and has two docks available. This boat launch also has several parking spots available for trucks and trailers. There is a four-lane concrete ramp, loading piers, and large parking area. Restrooms, picnic area, and shore fishing sites are also included. While there is no direct swimming access here, testing E Coli at various access points across Lake Winnebago gives boaters and other water users a better idea of how water quality can vary across the Fox River Basin within our county.
