A U.S. Army Corps of Engineers, St. Paul District, survey team was on Lake Pepin, near Red Wing, Minnesota, Feb. 12, collecting its annual ice measurements. The team measures the ice thickness at various points in the lake and provides the information to the navigation industry to help them determine when it's safe to break through the ice and begin the 2020 shipping season. The survey team's measurements indicated that the thickest part of the lake this year was 17 inches.
