Description
Lock 75 is the final and farthest lock West on the C&O Canal. This lock has a ten-foot lift for a total elevational change of 609.193 feet above the Georgetown tidal lock.
Although numbered as Lock 75, there are only 74 locks along the Canal. This discrepancy was an engineering error in the planning stage for Locks 62 – 66. Engineers thought four locks would be needed to make the step up but then discovered that only three steps were required during construction. Lock 65 was skipped, but since the lock numbering system was already in place, this lock’s name stayed Lock 75.
Lockhouse 75 is one of the final lockhouse to be built along the Canal and one of very few remaining log cabin lockhouses. It was damaged in the March 1936 flood after the Canal had already closed, and then a dust beetle infestation nearly finished off the structure. While the log home sits on its original foundations, only a few original timbers could be used in this 1978 reconstruction.
