Lower Wisconsin State Riverway
Hwy. 130/133 Bridge Replacement Notice: The Hwy. 130/133 bridge at Lone Rock in Iowa/Richland/Sauk counties will be closed throughout 2023 due to the replacement of the bridge structure. During construction, the south/main channel of the Wisconsin River will be closed at the bridge construction zone. All thru-traffic motorized watercraft should use the north channel to navigate around the bridge closure. A portage crossing at the closed bridge area will be available for small watercraft (canoes, kayaks, etc.) that can be carried around the bridge construction zone. For more information, please see:
Water Levels and River Flow
River flow can change overnight with excessive rain or through water level management of Lake Wisconsin that is through the Alliant Energy/Wisconsin Power and Light Company-Prairie du Sac Hydroelectric Project. Learning what the water levels are doing can help you determine if your trip will be difficult in low water times or hazardous if the water is high. Taking note of the river conditions using these services will help you in planning future river trips. Always secure your canoe and equipment well.
