The U.S. Army Corps of Engineers, St. Paul District survey team took the third ice thickness measurements of the season on Lake Pepin Wednesday.
The thickest ice is 22-24 inches between river miles 769 and 772, between the foot of Lake Pepin and Lake City. The thinnest, 8-16 inches, was measured between river miles 777 and 781.
The Motor Vessel R. Clayton McWhorter was the first tow to pass through Lake Pepin last year and reach St. Paul, arriving March 19th.
Historically the average date in which navigation is open occurs during the third week of March.
The next ice measurement will be Wednesday, March 9th.
