DULUTH, Minn. — The crew of the Coast Guard Cutter Alder, a 225-foot Seagoing Buoy Tender homeported in Duluth, commenced removing and replacing aids to navigation last week as part of the annual Operation Fall Retrieve.
Operation Fall Retrieve includes the removal or replacement of vulnerable lighted buoys with unlighted buoys better suited for ice. Moving ice, a distinguishing characteristic in the Great Lakes, can temporarily submerge a buoy or drag it off station. This destroys the buoys light signal equipment, rendering it useless.
The Coast Guard reminds all mariners to use caution due to the changes in the buoyage system. The crew of the Alder is responsible for removing or replacing 59 ATONs in Lake Superior and Northern Lake Michigan.
"The crew of the Alder will ensure that the Great Lake's waterways remain navigable, safe and secure to all mariners, both professional and recreational," said Lt. Cmdr. Anthony J. Maffia, commanding officer of Cutter Alder.
