| USACE-mission "Across the river and two miles downstream lies New Cumberland, W.Va., the originally planned site of the lock and dam, and hence its namesake....The New Cumberland navigation project was constructed from 1955 to 1961, with the locks opening for traffic in November 1959. This facility eliminated the original Locks and Dams 7, 8 and 9 which were constructed by the U.S. Army Corps of Engineers between 1904-1914. The three replaced projects each contained a single lock and the old-style wooden wicket dam." |

| LaurelHollowPark First of the Army Corps of Engineers' Ohio River "super-dams" to go into operation is the $13.5-million New Cumberland Dam at Stratton, Ohio. The 1,315-foot long structure was built by Dravo Corp., Pittsburgh. The new high-lift dame raises upper pool level 15 feet. |

| USACE-whoops Dec 13, 2016: They shutdown the main lock when they noticed a sheen in the main lock. The sheen was caused by a failure in the hydraulic system that operates the gates and valves. The aux lock had been put out of service for a couple of years because of structural issues that prevent its safe operation. (Note that the upper gates of the aux lock are not closed. They can't close them and that is why that lock is shutdown. [triblive-dec15]) |
The "structural issues" for the aux lock concerns the upstream miter gates, not the lock's concrete. [WeirtonDailyTimes] But they waited until 2019 before they contracted for replacement gates. [govtribe]

| PittsburghCorps Flickr New Cumberland Locks and Dam Lockmaster Willy Maynard speaks to Tribune Review Tom Fontaine about the gate hoist mechanism above the facility. |
"Welders cut and capped faulty hydraulic lines that leaked 150 gallons of hydraulic fluid into the main chamber. To open and close gates at one of the locks, Maynard said, workers will use a 53-foot work boat to push and pull the gates, which stand about five stories tall. The complicated process figures to make it take at least twice as long for boats to get through the lock — from one hour, on average, to up to 2 1⁄2 hours. The lock, normally open around the clock, will be open only during daylight hours." The plan for a permanent fix is to replace the existing hydraulic system "with four self-contained hydraulic units that would sit on top of walls at the facility. The current system includes underwater lines buried in the sand, making repairs more difficult and increasing the risk for environmental contamination. The new system would cost about $2 million. Army Corps spokesman Jeff Hawk said officials plan to submit a request for emergency funding to cover the cost. Maynard said it could take six months to a year to secure the money." [triblive-dec15]
The failure occurred Dec 12, 2016, and the lock was reopened Dec 17, an outage of 5 days. They have fine tuned their procedure for using the 53' work boat so that lock time is extended by only 15 to 30 minutes. The outage delayed 11 tows. [triblive-dec17]
I looked through quite a bit of a Google search output trying to find when the permanent repairs were done. But I couldn't find any more info on the repairs.
The middle gates are obviously submersible tainter gates. Even though the other gates look like the sluice gates used in the Emsworth Dam, they are evidently just another design for regular (non-submersible) tainter gates. [spillway-design]

The first lock in this time-lapse video is this lock.
The lock/dam system is awesome to observe. In the early 60s, I remember barges loaded with cows, going toward Pittsburg. Our family made a special drive to see this. These is so much history of cargo and water transportation to be learned from the operations of this system. Thank you for this writing.
