Castle Rock Lake

Castle Rock Lake was manmade and built back in the late 1940’s by Wisconsin River and Power Company by constructing a hydro-electric dam called the Castle Rock Dam.  With an impoundment of 13,000+ acres of water, it is Wisconsin’s 4th largest body of water.  Castle Rock Lake is one of Central WI. most popular attractions and has been for many years.  Today it is used for boating, fishing and swimming with something going on nearly all the time.

Castle Rock Lake is part of the Wisconsin River Flowage System which includes Lake Petenwell (WI’s 2nd Largest) to the north.  From the Petenwell Dam, there is a little stretch of Wisconsin river before it opens up into Castle Rock lake.  After Castle Rock Dam the water turns back into the Wisconsin river and flows all the way to the Wisconsin Dells dam.  “You CANNOT boat from Lake Petenwell to Castle Rock Lake to the Wisconsin River because to the hydroelectric dams.”
