The Department of Natural Resources Hydrographic Operations works with the U.S. Coast Guard (USCG) to mark the major channels for the State of Maryland and places regulatory and danger buoys and signs statewide.
Notice of missing, damaged, or off station Aids to Navigation should be reported to the USCG Sector Baltimore at 410-576-2525.
