MKARNS Nav Notice No. SWL 14-24 Lock 8 Longer than Normal Lockage Times

Published Aug. 5, 2014

Mariners are advised that lockages at Toad Suck Ferry Lock (No. 8) NM 155.9, will require an additional 15 minutes each time the lock level is raised to the upstream water level.  One of the two valves that fills the lock to the upstream water level failed, and the additional time reflects use of one valve instead of two.  The length of downtime is unknown at this time.  Another notice will be distributed when the failed valve is returned to service.

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
