CLEVELAND - Coast Guardsmen bring Cleveland Harbor's East Basin Channel Lighted Buoy 11 aboard the U.S. Coast Guard Cutter Bristol Bay, based in Detroit, Dec. 2, 2010, to replace it with a smaller unlit buoy designed to better withstand damage from ice as Lake Erie freezes during the winter months. U.S., Canadian and industry partners work together to retrieve or replace about half of the lighted and unlighted buoys and beacons throughout the Great Lakes in an evolution known as Operation Fall Retrieve.
