Castle Rock Lake
Castle Rock Lake is a man-made lake created by the Wisconsin River Power Company in 1947 and completed in 1951. It is Wisconsin’s fourth largest lake and covers 16,640 acres with approximately 60 miles of shoreline. It is known for its sandy shorelines, which makes for great swimming, skiing and leisure boating.
The majority of the shoreline is undeveloped making the lake “less populated”. The lake’s depth varies from 8 to 20 feet in most places, with area in the old river beds reaching as deep as 30 feet. The structure created from river beds makes Castle Rock a very productive and consistent fishing lake. While walleyes, white bass and crappies are the most abundant, many northern pike, large mouth bass, small mouth bass and panfish are taken also.
The shores of Castle Rock Lake are dotted with public launch sites, and visitors can enjoy water skiing, swimming, sailing, and boating on its beautiful blue waters. Spectacular sunsets await along the many miles of wooded shoreline where 25,000 acres remain in their natural state.
