Interpreting the Evidence
Erie Basin Canal Boats, c. 1900
Suggested Teaching Instructions
Tightly packed canal boats in the Erie Basin, circa 1900.
A lock is a water-filled chamber with huge gates or doors at both ends. Locks were usually built in a series up the sides of a hill or mountain. The construction of the original five-step locks in Lockport presented a major engineering challenge. The canal had to rise up a cliff of solid rock that was sixty-six feet high. The locks were blasted out of the cliff by the canal workers. The double set of five combined locks was the design of Nathan S. Roberts. One set of locks was for ascending traffic that was headed west, and the other set was for descending traffic heading east. The town that grew up around this set of locks became known as Lockport.
