Navigation Notice

Mariners may experience intermittent delays of up to 4 hours, from 8 a.m. to 5 p.m. daily, from July 20 through July 24 at Murray Lock and Dam (No. 7) NM 125.4.  The intermittent delays are for the installation of a hydraulic control valve.  Longer lockage times may also be experienced due to one pump operation during this period.  If the work is completed ahead of schedule, the lock may reopen at that time.  However, unforeseen problems could require additional time.

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