Navigation Notice


                                                    MURRAY LOCK (No. 7) NM 125.4

                                                MCCLELLAN-KERR ARKANSAS RIVER NAVIGATION SYSTEM

The maintenance closure of Murray Lock & Dam (No. 7) is in effect through September 04, 2015.  While completing the pre-dewater dive inspection, corrosion of critical safety equipment was discovered that precludes dewatering the lock.  The maintenance focus has now shifted to above-waterline critical inspections and repairs.

During this closure a very limited number of commercial lockages can be accommodated when maintenance is not underway.  Any such lockage requires 24-hour advance notice and coordination with the Lockmaster and must adhere to the following restrictions:

 n  No lockage can start before 6 p.m.  All lockages must be completed by 5 a.m.  No exceptions will be considered.

 n  Tow haulage is not available, and no deck hands can be allowed on the lock walls, due to the presence of maintenance equipment.

 n  No crew changeouts or unnecessary delays will be permitted.

To schedule a commercial lockage during this closure, please contact the Murray Lockmaster, Tarik Holmes, at 501-454-5490 or 501-663-1997 between 6 a.m. and 5 p.m.    Again, 24-hour advance notice is required.

Questions or requests for additional information concerning this notice should be directed to James McKinnie in the Little Rock District Office, at (501) 324-5739 or (501)324-5096, or you may email
