Units from around the Coast Guard 9th District continue work on their annual retrieval of the Great Lakes and St. Lawrence Seaway System seasonal aids to navigation, the largest domestic ATON recovery operation in the U.S.
Operation Fall Retrieve, which affects lighted and unlighted buoys and beacons, began in mid October with a goal of retrieving 1,278 navigational aids.
The operation is scheduled to be completed by Dec. 28.
As of Thursday, 527 of the 1,278 aids have been decommissioned for the season.
