Fog/Wind Delays— No fog last night, expect high winds on the East and West Canals and Houston Ship Channel through the weekend.
Lock 52 Update: River is Closed – The upper gauge at Lock 52 is currently 13.9’, the river remains closed to protect loaded tows from hitting the wickets or grounding. The Corps is raising their “starter wickets”, these are wickets 1-20. If the river cooperates they will start raising the dam once work completes on the dyke today. They expect raising the wickets will take around 12-18 hours. Once they are raised, we will need to wait for the pool to build.
Best guess to begin locking late Friday/Saturday. It is important to remember that this is a fluid situation and things are changing quickly. A helper vessel remains onsite to shadow all vessels through the navigation pass and will be monitoring the radio and taking guidance from the lock operators.
The navigation pass is restricted to approximately 400 ft. to 450 ft. in the center of the pass and is marked by navigation buoys.
Work continues to remove Dike 2. Once everything is complete the lock will be operating more efficiently than it has in 20 years.
Lock 4, Allegheny River – The Corp advises that this will be a complete closure (no auxiliary lock). The Lock is to close at 0001 11/6/2017 and remain closed through 11 p.m. 12/22/2017. The lock is located above New Kensington. The cities of Natrona, Freeport, Schenley, and Kittanning PA will be affected by this closure.
UPPER MISSISSIPPI RIVER:
Mel Price (UMR 200.8) 3 day closure – Will begin at 0700 on 12/11 and end at 1800 on 12/13, these repairs are to fix the main lock lift gate which was struck in early October.
Rock Pinnacle removal at Thebes, restrictions added (UMR 38-46) – Work is ongoing.
Work will be done during daylight hours, estimate 0700-1900. During work hours, tows may pass, but are restricted to 28 barges northbound and 15 barges south-bound respectively. During non-work hours tows may pass unrestricted.
Chickamauga Lock (MILE 471 TN) will have a total closure 2/5/18 thru 4/19/18 with a 7 day opening TBD in the middle of the job.
