The U.S. Army Corps of Engineers, St. Paul District survey team was out on Lake Pepin Wednesday taking the first ice thickness measurements of the season.
The ice was a little thinner than normal, measuring 20-21 inches in many places.
The thickest ice is 20-21 inches between river miles 766 and 773, between the foot of Lake Pepin and Lake City. The thinnest was measured between river miles 780 and 781.
The information will be used by the navigation industry to predict when it’s safe to break through the ice and begin the 2022 navigation season.
The next ice measurement will be February 22nd.
