A sandbar in the Wisconsin River is covered by inches of water, left, but quickly drops off to deeper water. Timm Zumm, president of the Friends of the Lower Wisconsin Riverway, has been traversing the river for years and is often accompanied by his 12-year-old hound, Bowie, who also sports a life jacket.

Timm Zumm, president of the Friends of the Lower Wisconsin Riverway, lowers his kayak Thursday off a sandbar and into the shallow water of the Wisconsin River west of Gotham. Zumm is adamant about users of the river wearing life jackets since its features include strong currents and sudden drop-offs.
Life jackets offered free of charge to visitors to the Lower Wisconsin State Riverway share a new kiosk at the boat landing in Avoca. The kiosks — a collaboration among the Friends of the Lower Wisconsin Riverway, Department of Natural Resources and service organizations — can be found at more than a dozen landings along the 92-mile stretch of river between the Prairie du Sac Dam and the Mississippi River.
The top sign at the boat landing near Gotham alerts visitors to strong currents and deep drop-offs in the Wisconsin River. Another sign asks people to be on the lookout for the remains of Parker Kruse, who was thrown from a boat near Spring Green last July.
