Annual ice measurements begin
FRONTENAC, Minn. –Brandon Olson works the auger and Thomas Burrows, both St. Paul District channels and harbors, measures the ice at the Mississippi River’s Lake Pepin Feb. 15. Starting at around 8:15 a.m. at Camp Lacupolis, crew members rode an airboat to various points of the lake and used an auger to drill through the ice. They then measured the thickness of the ice through the holes. They said the thickest ice measured 17 inches, located about 1 mile southeast of Lake City. But that quickly changed just 3 miles north of Lake City, where the crew encountered open water. – USACE photos by John Barker
