LAKE CITY, Minn. – The ice pack on Lake Pepin’s navigation channel remains as thick as 22 inches, the Army Corps reported. The ice, however, has deteriorated in the past week. At the thickest checkpoint, with 22 inches, only 17 inches is solid blue ice. The other five inches is “white ice” with bubbles. At five of the Corps’ 22 checkpoints, the lake is clear of ice.
