RedactedNarrative: On July 10, 2018 an unknown vessel struck an aid to navigation marker B-6.  The marker is located on the Blackwater River Arm of Smith Mountain Lake in Franklin County.  The wooden piling supporting the  solar light and marker was broken just above the waterline.  VSP divers were able to locate an item that we believe could have come from the hit and run vessel.  The marker has been replaced at a cost exceeding $6,000.00.  Damage estimates for the striking vessel are unknown at this time.
