Fishing Castle Rock Flowage Wisconsin

Located just south of the “sister” Petenwell Flowage, Castle Rock Flowage at 16,640 acres and 36 feet maximum depth offers a superb Wisconsin River fishing resource that continues to get better every year.

Today’s clean waters offer outstanding habitat that provides for good natural reproduction for walleye, smallmouth bass, crappie, as well as other species. Growth rates are typically above the state average.

Today a trophy muskie component is present, largely the result of state and private stocking efforts. Other species complement the resource – channel catfish, white bass and sturgeon.

Besides the main lake, the Little Yellow River arm offers both lake and river fishing, including a significant walleye run in early spring. As part of the Wisconsin River system, this flowage offers year-around walleye fishing with action starting as soon as ice breaks up.
