- ST LUCIE RIVER - ST LUCIE RIVER NORTH FORK ATON / Advanced Notice of Change ATON/Advanced Notice of Change 22880 Location: 27-12.55N 080-16.17W Aid Name: St Lucie River (North Fork) Daybeacon 5 LLNR: 50855 Action: CHANGE Action Type Change Aid Subtype The U.S. Coast Guard has approved the following change in the St. Lucie River. St. Lucie River N. Fork DBN 5 (LLNR 50855) will be changed to St. Lucie River N. Fork LT 5, using the same LLNR. This aid is currently located near a bend on the St Lucie River (North Fork) and unlighted. Given the turn for the channel it is best to install a light on the aid to provide a better signal during nighttime hours. There are currently no lighted aids in the immediate area. Lighting this aid would keep the maritime community safer and assist with navigation while transiting the river. USCG Southeast District Local Notice to Mariners 45/2026
