I talked with the USCG Navigational Aid guy last night and he informed me of the following regarding St. Lucie Inlet....

They started dredging on 2/8. He reset the markers and the dredge pipes are running across the channel where there is 4'-6' of depth in the center. The pipes were hit several times the first day and some of the folks with local knowledge are running outside of the channel but are dangerously close to hitting the pipes. Be cautious if you plan to use the inlet.
