Erie Canal - Locks. The present Erie Canal rises 566 feet from the Hudson River to Lake Erie through 57 locks. From tide-water level at Troy, the Erie Canal rises through a series of locks in the Mohawk Valley to an elevation of 420 feet above sea-level at the summit level at Rome. Continuing westward, it descends to an elevation of 363 feet above sea-level at the junction with the Oswego Canal, and finally rises to an elevation of 565.6 feet above sea-level at the Niagara River. The original "Clinton's Ditch" Erie Canal had 83 locks. The Enlarged Erie Canal, built between 1835 and 1862, saw this number reduced to 72 locks.
