SPECIAL LOCKING INSTRUCTIONS
COLONEL CHARLES D. MAYNARD LOCK (No. 5) NM 86.3
MCCLELLAN-KERR ARKANSAS RIVER NAVIGATION SYSTEM

Due to a damaged upstream river wall miter gate leaf caused by a recent allision, mariners are advised that all tows approaching Colonel Charles D. Maynard Lock (No. 5) NM 86.3 are required to come to a complete stop before receiving instruction to enter the lock chamber to ensure that entrance speeds into the lock chamber do not exceed 200 feet per minute (equivalent to the rate of a slow walk) as outlined in Navigation Notice No. 1-2023.

Prior to receiving instruction to enter the lock chamber, all upbound tows are required to stop 100 feet downstream of the recessed downstream miter gate leaves and all downbound tows are required to stop 100 feet upstream of the recessed upstream miter gate leaves. This requirement is in place to reduce the risk of further damage to the miter gate leaf due to another allision, which could render the Lock inoperable. This restriction will be lifted once necessary repairs to the miter gate leaf can be made.

Questions or requests for additional information concerning this notice should be directed to the Little Rock District Office at (501) 324-5096 or you may email CESWL-OP-OM@usace.army.mil.
