PN 16-02 ICE RESTRICTIONS Lock and Dam 24

  1. All navigation interests are advised that effective immediately, until further notice, the St. Louis District is imposing a 70-foot width restriction on all tows which traverse Lock 24. Lockages may also be delayed due to ice formation on miter gates. Ice formation along the walls of the lock chambers and miter gates has prompted
    this decision.
  2. Ice couplings will be required.
  3. All tows are cautioned to be alert for changing conditions and possible hazards due to ice formations. Severe navigation problems can always be expected throughout the ice-forming season.
  4. All navigation interests should be alert for, and abide by, any special instructions that may be issued by the Lockmaster.
