Petenwell Lake

It is located in Adams, Juneau, and Wood counties next to Castle Rock Lake.

Private lakefront property is very limited as most of the virgin shoreline is undeveloped forest.

In 1973, the Juneau County extension resource agent submitted a letter on behalf of the County Industrial-Recreation, and Agriculture and Education Committees to the Wisconsin Power and Light Company requesting a nuclear power plant be constructed near the lake.
