The Pittsburgh District is home to the Upper Ohio River Lock and Dam system, defined as Emsworth, Dashields and Montgomery (EDM). They were the first three navigation projects on the Ohio River, making them the oldest and smallest locks in the system. All are situated near Pittsburgh, PA. Emsworth Locks and Dam Emsworth Locks and Dam’s main channel dam is located at river mile 6 near the towns of Emsworth, Avalon and Ben Avon, PA. The locks first opened in September 1921. The Corps rebuilt and converted the dam to a gate structure between 1935 and 1938. This action raised the pool an additional 7 feet to accommodate larger, more modern barges. From 1981-86, some $30 million was invested in a major rehabilitation of the facility. Rehabilitation included the replacing of electrical systems, operating machinery and buildings and re-surfacing of the lock walls. Dashields Locks and Dam Dashields Locks and Dam is located on the left descending bank at river mile 13.3, a few miles upstream from Aliquippa, PA. It opened for navigation in August 1929.
