Local Notice to Mariners

UPPER MISSISSIPPI RIVER - CHANNEL CONDITION/SAFETY ADVISORY - UPDATE
The Upper Mississippi River Zone 28 (Miles 185.4-109.9) is in the extreme high water action phase in accordance with the Western Rivers Action Plan Annex. Recreational traffic is not recommended.  Towboat operators should use caution, minimize wake where possible and have a pilot onboard with recent experience during high water operations with tows of similar size.  Mariners should remain vigilant to an increase in debris and maneuver appropriately, be aware that a buildup of debris in fleeting areas may have occurred and take appropriate action to prevent any breakaways. Mariners should use caution in all passing and meeting situations, and confirm navigational clearances prior to transiting under bridges. Navigational buoys may have been dragged off station so remain cautious while transiting and favor center channel.  Laying up on levees is prohibited and barges should not be carried on the hip.  Down-streaming operations not recommended for vessels operating under 1,800 horsepower.  Within the St. Louis Harbor (Mile 184.0 – Mile 179.0), south-bound tows greater than 600 feet in length, excluding the towboat,  
should limit their transit to daylight hours only.  All towing vessels should have a minimum of 250 H.P. for each loaded barge and proceed at their
slowest safe operating speed based on prevailing conditions.  North-bound tows must have sufficient horsepower to maintain a minimum of 3 MPH, on approach to the St. Louis Bridges.
