Visitors have an opportunity to fish for crappie, bass, bluegill and walleye. Red fox scurry along the shoreline and pileated woodpeckers can be heard knocking on dead trees. Spring is a wonderful time to view colorful warblers. Snapping turtles and painted turtles loaf on downed trees. In the skies the great blue heron, great egrets and double-crested cormorants fly from their treetop nesting areas to feed in the shallow backwaters of the river.
