The ice on Lake Pepin is starting to loosen but still remains over two feet thick just above Reads Landing.
The U-S Army Corps of Engineers' latest reading taken Wednesday shows the ice is 26 inches deep just above Reads Landing. But that includes 13 inches of blue, or solid, ice and 13 inches of white ice which contains snow and air bubbles.
Seven other sites on the lake are at least 20 inches thick with all solid ice.
The ice depth has delayed any towboats from coming this far north on the Upper Mississippi River. No topwboats have reached the Winona commercial harbor yet.
As of Wednesday the nearest tow went through Lock and Dam 13 at Fulton, Illinois just before noon pushing four barges upbound.
The opening of the navigation season has been pushed back a couple of weeks with the cold winter.....
