The Erie Canal: Connecting the Great Lakes to the Atlantic Ocean

The Erie Canal is a 584 km (363 mi) artificial waterway in New York State that connects the Great Lakes (via Lake Erie) to the Atlantic Ocean (via the Hudson River).

Terminal Points

• Western Terminus: Buffalo, NY — on Lake Erie (eastern end). Elevation: 174 m (571 ft).
• Eastern Terminus: Waterford, NY (near Albany) — on the Hudson River. Elevation: 4 m (14 ft).
• Hudson River flows south to New York Harbor / Atlantic Ocean.

Lock System & Engineering

• 35 locks (originally 83; enlarged 1835–1862, 1905–1918 Barge Canal).
• Overcome 170 m (565 ft) elevation difference.
• Lock chambers: 91 m × 13.7 m (300 ft × 45 ft) — accommodate barges up to 3,000 tons.

Historical Impact

• Opened 1825 — "Wedding of the Waters" (DeWitt Clinton).
• Reduced freight cost 90%; cut travel time weeks → days.
• Made NYC the premier Atlantic port; opened Midwest settlement.
• Spurred canal boom, then railroad competition.

Modern Erie Canal (New York State Canal System)

• Part of 845 km (525 mi) system: Erie, Champlain, Oswego, Cayuga-Seneca canals.
• Primarily recreational (boating, cycling Erie Canalway Trail), some commercial.
• Managed by NYS Canal Corporation (Thruway Authority).

Geographic Context

The Erie Canal links the Great Lakes–St. Lawrence basin to the Atlantic slope. It does not directly touch Lake Ontario (that's the Oswego Canal) or Lake Champlain (Champlain Canal), but it is the trunk line.

The Erie Canal physically and economically stitched a continent together.
