It’s a sign that spring is near, as the U.S. Army Corps of Engineers, St. Paul District, will start its annual Lake Pepin ice measurements Wednesday, February 15th.
The Corps takes ice measurements on Lake Pepin annually to forecast the navigational outlook.
The lake’s ice is the last major barrier for vessels reaching the head of the navigation channel in St. Paul.
The information is used by the navigation industry to predict when it’s safe to break through the ice and begin the 2023 navigation season.
Ice measurements are typically completed weekly until the first tow arrives.
Historically the average date in which navigation is open occurs during the third week of March.
The Motor Vessel W. Red Harris was the first tow to pass through Lake Pepin last year and arrived in St. Paul on March 21st.
