This lock runs through the city of Lockport, New York, and enables boats to continue up the Erie Canal to Lake Erie. Ground was broken in Rome, New York, in 1817 to commence the building of the Erie Canal, which was opened in 1825.
A lock is an enclosure with a gate at each end that is used to raise or lower boats from one water level to another on a river or canal. A boat enters a lock through one gate. The gate is then closed, and the water level in the lock rises or lowers until it is equal to the water level on the opposite side. The gate on the opposite side opens, and the boat can continue on its journey.
