Anglers and boaters planning to enjoy the scenic features of the lower St. Croix River in the coming days are reminded that slow no-wake restrictions are in effect because of high water caused by recent rains.
Boaters on the St. Croix between Taylors Falls and Prescott must operate at slow no-wake speeds when the river’s level is at or above 683 feet above sea level at Stillwater. The special restriction, authorized by state rules in both Minnesota and Wisconsin, is aimed at reducing shoreline erosion and resulting property damage in areas not usually susceptible to wave action at lower water levels. Recent heavy rains caused the river to reach that level Wednesday.
The slow no-wake rule will remain in effect until the water level drops below the 683-foot level. Boat and water safety officials at the DNR also point out that high-running rivers often contain debris floating just below the surface that can pose serious hazards. Boaters should slow down and exercise extra caution in such conditions. Boaters can consult the National Weather Service website for the latest updates on current and projected water levels.
