Lake Pepin Ice Measurements




It’s a sign that official spring is near, as the U.S. Army Corps of Engineers, St. Paul District, despite the recent warm weather, will start its annual Lake Pepin ice measurements next week.


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 will be used to predict when it’s safe to break through the ice and begin the 2024 navigation season.


Historically the average date in which navigation is open occurs during the third week of March but it may be sooner than usual due to the recent lack of cold temperatures.
