Features
Located in south central Wisconsin, this section of the Wisconsin River runs from the Castle Rock Dam downstream to Wisconsin Dells, Wisconsin. The Upper Wisconsin Dells area attracts thousands of visitors with its outstanding natural beauty and wide range of recreational activities. Excursion boat tours through the scenic rock formations of the Upper Dells are popular. Pleasure and excursion boat traffic can be extremely heavy during summer. Anglers should concentrate their efforts during early morning and evening hours to avoid conflicts.
The Wisconsin River between Castle Rock dam and the Upper Dells is best suited for small fishing boats and canoes. Most of the shoreline remains unspoiled with only limited development.
Forage
White sucker, juvenile white bass, carpsucker and spotted sucker are the primary forage species. River shiner and other species will also be utilized in smaller amounts. Young of year bigmouth buffalo will provide forage.
Seasonal Movements
In early spring, walleye and white bass move to the tailwaters below the Castle Rock Dam to spawn. The best walleye action usually occurs in late February and March. White bass activity will peak in May.
