The U.S. Army Corps of Engineers has reopened the main chamber of Dashields Lock and Dam on the Ohio River. Crews are currently refilling the dewatered Emsworth main chamber which is to be reopened Sunday at 11 p.m.
The 100 foot by 600 foot main chambers at both Dashields and Emsworth Locks and Dams were closed since July 6th to make critical repairs to the lock structures. The small chambers at each facility remained open during that time. Crews repaired three 110 to 125 ton miter gates in the main lock chambers at Dashields. These are the large gates that open and close when vessels move through the locks.
At Emsworth, workers repaired the main chamber's deteriorated emptying valves that are used to lower water levels in the lock.
District Engineer Colonel Michael Crall said "it's not easy keeping these aging structures operational. The facilities are more than 80 years old.
