The USCG has issued a Notice to Mariners announcing the establishment of emergency anchorage space for use during High Water and Fog Conditions.
Note there is ongoing federal rule-making in place to establish the added anchorage space permanently.  Until that process is finalized, the space will be available on an emergency basis as described below.

In accordance with 33 Cude of Federal Regulations 110.195 (b), the following temporary anchorages are being established only as emergency anchorages to alleviate vessel congestion and plan for use during High Water and Fog Conditions. No vessel shall occupy these temporary anchorage areas unless expressly authorized by Vessel Traffic Service New Orleans.
The following existing anchorages are being temporarily extended to include the below mile markers only.
Existing descending banks and widths, as outlined in 33 CFR 195 remain unchanged.

  • Boothville Anchorage: An area, 0.95 miles in length, from Mile 12.05, AHOP – Mile 13.0, AHOP.
