Turtle Lake is a 141 acre lake located in Walworth County. This spring fed lake has a 85% muck and 15% sand mix that makes up the bottom, it has a maximum depth of 30 feet. The lake's water is moderately clear. Visitors have access to the lake from a public boat landing on the West side. Fishermen can expect to catch Panfish, Largemouth Bass and Northern Pike.
What also makes this lake unique is that the D.N.R. purchased 5,000 acres and turned it back into wetland called The Turtle Lake Wildlife Refuge. The Refuge is one one side of the lake and the Kettle Moraine is on the other.
