Enlarged Erie Canal Lock No. 33 is located in Montgomery County, in the Town of Minden, on the south side of the modern canal and the Mohawk River at the end of Dump Road. St. Johnsville is directly opposite on the north side of the canal and river, and the lock is therefore called the St. Johnsville lock. It is a double-chamber lock, with the south chamber double-length on the head (western) end, and had a lift of 6.031 feet to the west. Enlarged Erie Canal Lock No. 33 was built in 1838-1840, and the south chamber was lengthened in 1887/1888. Only three other locks on the Enlarged Erie were lengthened at the head end owing to the amount of excavation necessary on that end.
