The U.S. Army Corps of Engineers Pittsburgh District announces it is postponing the Dashields Locks and Dam event scheduled for tomorrow, April 4, due to high water conditions on the Ohio River.  The river conditions required us to fill the lock chamber to provide essential stability to the lock chamber. 

The three locks in the Upper Ohio Navigation Project include Emsworth, Dashields and Montgomery Locks. The locks range in age from 81 to 96 years old.  All three sites are experiencing various conditions and reliability issues on key systems, including the lock walls, gates, electrical and mechanical components.  The condition of the lock walls is the primary component driving the lack of reliability within the Upper Ohio Navigation Project.  The lock walls exhibit three major areas of concern: stability problems, advanced concrete deterioration and widespread cracking issues throughout the length of the locks walls. These conditions do not meet current Corps design criteria. 

As soon as conditions on the river and the maintenance timeline warrant, the district will reschedule the event.
