HIGH WATER SAFETY ADVISORY: VTS Measure at MM 167.5 to MM 254.5 AHP LMR (ABOVE 35')

When the Baton Rouge gauge reads above 35', a U.S. Coast Guard Vessel Traffic Service (VTS) Measure is established in accordance with the Navigation Safety Regulations, code of Federal Regulations Title 33, Subpart 161.11, for all waters of the Lower Mississippi River (:MR) from Mile 167.5 Above Head of passes (AHP), to Mile 254.5 AHP. This VTS Measure is needed to protect persons and vessels from the potential safety hazards associated with the following provisions.

Port Allen Lock LMR MM 219-229

	1.all vessels are required 1 horsepower (HP) per 5 tons or 280 HP per regulation loaded barge for canal tows entering/exiting the Locks, Empty barges may be calculated at 1/2 the horsepower requirements to that of a 	loaded barge when computing the overall horsepower requirement. VTS may on a case-by-case basis grant exemptions to this requirement based on conditions and size of tow.
	2. All tows exiting PAL into LMR intending to turn northbound shall get approval from VTS and use an assist vessel of at least 1200 HP, or proceed south to MM 221 to top around unassisted.
	3. All tows>600feet (excluding towboat) entering and exiting the lock must use an assist vessel with a minimum of 1200 HP and when topping around between MM 229-221

	2. all Vessels are limited to a max tow size of 30 barges with 280HP per barge for down bound transits within this area. Empty barges may be calculated at 1/2 the horsepower requirements to that of a loaded barge when 	computing the overall horsepower requirement. Vessels unable to meet the HP requirements must make adjustments to meet the requirements prior to transiting Wilkinson Point. VTS may on a case-by-case basis grant 	exemptions to this requirement based on conditions and size of tow. 
	3. An 8000 HP towing vessel is authorized to push a 30 barge tow (400 HP less than the requirement stated in paragraph 1 above)
