Anglers who just can't wait for the May 14 Minnesota fishing opener and fish for walleyes and northerns beginning Saturday on the St. Croix River. The walleye limit is six, with a 15-inch minimum size. The northern limit there is five. Anglers on the lower St. Croix are reminded that slow, no-wake restrictions remain in effect. Boaters 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 property damage. The slow no-wake rule will remain in effect until the water level drops below the 683-foot level. The DNR also warns boaters that high-running rivers often contain debris floating just below the surface that can pose serious hazards. The DNR says boaters should slow down and exercise extra caution. Boaters can visit the National Weather Service website for the latest updates on current and projected water levels at www.weather.gov/ahps.
