Navigation Notice

Due to the ongoing COVID-19 concerns, mariners are required to follow the below procedure for crew change out at all MKARNS Locks in Little Rock and Tulsa Districts:

Industry shall contact the Lock 4 hours in advance of anticipated crew change. Number and names of the crew will be provided along with delivery of supplies.  No industry personnel shall be allowed inside USACE control houses or buildings during crew changes, except in the case of medical emergency. Crew changes will still be allowed on the lock wall but industry must go directly from the vehicle to the motor vessel. Industry personnel will be required to use their own facilities while navigating through the lock.  The physical exchange of trip tickets from crew members to lock staff members will still not be allowed and must be communicated by some other means prior to transiting the lock. These changes are effective immediately and will remain in effect until further notice.

Questions or requests for additional information concerning this notice should be directed to:
