General / Hazards To Navigation / Shoaling Reported
Location: 41-43.63N 086-54.63W Description: The Coast Guard has been notified of significant shoaling on the western side of the Michigan City Harbor Channel in vicinity of Michigan City West Pierhead Light (LLNR 19565). In response, the Coast Guard has temporarily deployed two red buoys, Michigan City Shoal Lighted Buoy 2 and Michigan City Shoal Buoy 4, to mark the furthest encroachment of the shoaling. Michigan City Shoal Lighted Buoy 2 has a QR characteristic and should be used as the primary starboard hand mark when entering the harbor channel. In an effort to prevent confusion, Michigan City West Pierhead Light (LLNR 19565) has been temporarily disestablished until dredging can be completed. Mariners are urged to use caution when transiting the area and are discouraged from transiting inside the temporary buoys and west pierhead.
