Brothertown Harbor is a 9-acre Lake Winnebago boat launch facility located approximately 8 miles south of Stockbridge, featuring three wide paved launch lanes, a breakwater, ample paved parking, and a permanent pit toilet.

The harbor was remodeled in 2009 with dredging and expanded in 2016 with additional parking and a playground. Daily launch permits cost $6. 00 on-site, or seasonal permits ($40) provide access to three county harbors.
