Vessel Traffic Service (VTS) Lower Mississippi River, in accordance with the Navigation Safety Regulations, Code of Federal Regulations Title 33, Subpart 161.11, will establish a series of VTS measures for all waters of the Lower Mississippi River from Mile Marker (MM) 0.0 to MM 2.0, Above Head of Passes (AHP). These measures are needed to protect persons and vessels from the potential safety hazards associated with the removal of the Hopper Dredge Disposal Area (HDDA) discharge pipeline that is crossing the navigation channel, and are in effect with the following provisions:

·       March 18, 2025, from 8:00 a.m. to 8:00 p.m.: Full channel closure between MM 0.0 and MM 2.0, AHP. All vessels are prohibited from transiting this area.

Pilot boats are exempt from the above provisions during river closures.
Vessels intending to arrive or depart the Mississippi River on the day of a closure must arrive at Pilottown (outbound) no later than 7:30 a.m. or Southwest Pass Entrance Light (inbound) no later than 6:00 a.m.

CARROLLTON GAUGE AT 12 FEET AND FALLING
The Carrollton Gauge reads 12 feet and falling, the following operating requirements are no longer in effect:
  1. For barge fleets located between MM 88 and MM 240 AHP, additional high-water requirements are found in 33 CFR 165.803(m). 
  2. For all other barge fleets (below MM 88), a Safety Zone in accordance with 33 CFR 165.20 or other Traffic Control Measures may be established to enhance the safety of barge fleets. The 33 CFR 165.803 regulations requiring stricter barge fleeting standards on the LMR may be extended to include all barge fleets in these areas. 
  3. Downbound vessels planning to transit Algiers Point are prohibited from towing on the hawser without prior permission from Vessel Traffic Service LMR. 
The following operating requirements remain in effect:
  1. In addition to the requirements contained in 33 CFR 161.13, the following measures apply to vessels transiting through or within the Algiers Point VTS Special Area:
    1. No vessel shall enter or get underway without prior approval of the VTS and must abide by any direction or measures issued by the VTS.
    2. A vessel awaiting a VTS direction to proceed must keep clear of other vessels transiting.
    3. Vessels shall not enter the Special Area if a hazardous vessel operating condition or circumstance exists, as defined in 33 CFR161.2, without prior approval from the COTP.
    4. Vessels shall not meet, cross, or overtake any other vessel in the Special Area without prior approval from the VTS. If the VTS approves the maneuver, before executing the maneuver, vessels shall communicate on the designated bridge-to-bridge radiotelephone frequency intended navigation movements and any other information necessary in order to make safe passing arrangements. 
  2. As required by 33 CFR 165.810(b)(3), 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). 
  3. For all vessels operating in the Lower Mississippi River (LMR) below Mile Marker (MM) 233.9 Above Head of Passes (AHP), including South Pass and Southwest Pass, additional high-water requirements are found in Title 33 of the Code of Federal Regulations (CFR) 165.810.

  5. Downbound Ocean-going Towing vessels towing on the hawser should consult with the appropriate pilot association to determine the need for assist tugs.
Lower Mississippi River Bridges Air-Draft Calculations:

​The above clearances were calculated this morning using gauge readings provided by the Army Corps of Engineers. As a guide the pilots require at least an additional 3 feet of clearance for the Vessel's Air Draft.  The individual pilot assigned to the vessel will make the final determination of the vessel's allowable clearance.  Actual clearance should be verified when ordering pilot services.
