Fishing

Fishing and Boating

Along the Rock River, Castle Rock offers 1 1/2 miles of bank fishing. A boat ramp is available for public use, where boat size is limited due to the varying depth of the river. The most commonly caught fish is the catfish, but some bass, northerns, walleye, and crappie may be taken.

A state fishing license is usually required.
