Castle Rock Lake, WI

A popular destination for a fishing trip or a vacation, Castle Rock Lake is a 14,000-acre lake in the central part of the state, at Necedah, WI. There is 60 miles of shoreline, some of which can be accessed for fishing from the bank at public boat landings, public beaches and campground areas.

Multiple boat launch ramps make for easy launching of pleasure or fishing boats. In winter, ice fishing is popular when the ice is safe.
