Corps of Engineers completes first Lake Pepin ice measurements
WABASHA, Minn. – Bill Chelmowski, U.S. Army Corps of Engineers, St. Paul District marine machinery mechanic, uses an ice auger to drill a hole on Lake Pepin, near Wabasha, Minn., Feb. 13, during the first Mississippi River ice surveys of the year. The district conducts the annual ice surveys to help the navigation industry determine when it is safe to break through the ice. Lake Pepin, located on the Mississippi River between Red Wing and Wabasha, Minn., is used as the benchmark because the ice melts slower in this area due to the lake width and the slower current.
