The Carrollton Gauge reads 8 feet and rising, the following operating requirements are in effect:

1. In accordance with 33 CFR 161.65, the Governor Nicholls Harbor Traffic Control Light 94, the Gretna Harbor Traffic Control Light 97 and the Westwego Traffic Light 102 are energized.

The Harbor Traffic Control Lights are located at:
Governor Nicholls Light, MM 94.3, AHP, LDB, LMR (LLNR 13855/34770), Gretna Light, MM 96.6, AHP, RDB, LMR (LLNR 13880/34795), and Westwego Traffic Light, MM 101.4, AHP, RDB, LMR (LLNR13950).

3. In accordance with 33 CFR 160.111 (c), the COTP has determined that during periods of high water, unless moored to a shore side facility or mooring buoys, all deep draft vessels must have three means to hold position. An example would be two fully operational anchors and the propulsion system. Should a vessel lose an anchor or suffer a propulsion casualty, and the vessel does not have redundant capabilities available, such as aft anchors or two main engines, then a third means of holding position could be via tug assist.

4. Mid-Stream cargo transfers must be preceded by 48-hour notice (See Enclosure 2 for Midstream Transfer Notice form).

Midstream cargo transfers may be conducted at the designated anchorages within the New Orleans COTP zone as defined by 33 CFR 110.195(a), with exception of the General Anchorage (MM 90.1 – 90.9 AHP) and the Quarantine Anchorage (MM 90.9 – 91.6 AHP). This requirement does NOT affect:

a. Vessel-to-vessel transfers occurring at a Coast Guard regulated facility.
b. Bunkers or delivery of ships’ stores.
c. Cargo operations occurring in a designated and established mid- stream buoy system.

Anyone wishing to conduct vessel to vessel cargo transfers not specifically exempted as noted above, should submit a MidStream Transfer Notice form to

5. All vessels, facilities, and vessel agents planning to warp a vessel should consult with the appropriate pilot association prior to warping.

6. Tows are prohibited from transiting VTS special areas by a vessel with insufficient power to permit ready maneuverability and safe handling (unable to maintain an average speed of at least 3 MPH (2.6 knots).
