SUSPENDED - Navigation Number 2027, PN 13-06

ASSIST VESSEL REQUIREMENTS
Lock 27

  

 

1. All navigation interests are advised that due to the St. Louis Gage falling below stage 27.0, the assist vessel will not be required for all Northbound tows approaching the main lock chamber at Locks 27. Should the stage at St. Louis rise above 27.0 feet, the requirement will be reinstated. This mandate is necessary to prevent misaligned tows from impacting the lower east wall miter gate in the recess during north bound approach. At river stages below 27’ the miter gate has timbers to protect the structural members. Please exercise extreme caution during approach to the lock.

2. All navigation interests should be alert for, and abide by, any special instructions that may be issued by the lockmaster.
