The ice covering Lake Pepin is melting, but remains over 2 feet thick in some areas. A team from the US Army Corps of Engineers ventured back onto the ice on Wednesday for another round of measurements and found the thickest ice is still near the foot of the lake just north of Wabasha at 26 inches. That’s down about 6 inches when compared to the first round of measurements in late February, and about half of it is softer white ice. While that sounds promising for businesses and others waiting for the commercial shipping season to begin, the ice from that point north to Lake City is still the harder blue ice and remains between 20 and 23 inches thick.
