Lock No 7 at Mile 36.5 below Pittsburgh is identified as Midland, PA, although it is nearby Georgetown. The lock master’s residence is on the south bank approximately 2.5 miles from Georgetown. There is only one access road from Georgetown to the facility, appropriately named The Dam Road.
In 1913, a year of serious flooding on the Ohio River at Easter, Lock No 7 was under construction. When the Montgomery Dam was opened in 1959 Lock No 7 ceased operations.
