9 p.m. update to today’s lead story: High water on the St. Croix after headwaters hit by torrential rain, flash flooding.
Dam destroyed
Radigan Dam on the Upper Tamarack River, which authorities warned was ready to fail earlier today, has met the prediction. The contents of the lake formerly behind the dam are now headed downstream several miles to the St. Croix.
A flash flood warning is in effect, with all bridges across the Upper Tamarack below Radigan Dam closed.
There are numerous cabins and properties along the stretch, and we wish them good fortune.
