Black Rock Lock

The Black Rock Lock is a ship lock in Buffalo, New York, that allows vessels to bypass rapids on the Niagara River at the outlet of Lake Erie. The lock chamber is 650 feet (200 m) long, 70 feet (21 m) wide, and rises 26 feet (7.9 m). The original lock at Black Rock was built in 1833 following the completion of the Erie Canal. The current, larger lock was completed in 1913.
