In some historical writings, the old Wedge Mill is credited to Muskego. It was recorded this way based on the written and oral testimony of many old settlers. The error was understandable because at that time, town boundaries were not well known and the mill was located only a few feet north of the line between New Berlin and Muskego.
The mills spurred development, and in the 1920’s, John Blott subdivided the shore and renamed it Linnie Lac after his wife Malina (Linnie). Sometime between 1840 and 1850, a post office operated in the area called Muskego Mills.
In June 1997, flooding threatened the dam and the Wisconsin Department of Natural Resources dug a trench around it to avoid flooding downstream in Muskego. Since no owner could be found, the homeowners formed the Linnie Lac Management District and took over ownership of the dam and worked out a taxing system to repair the dam. Completed in 2000, the dam was subsequently declared a New Berlin Landmark..
