Navigating the Great Lakes: How Ships Can Overcome Niagara Falls and Reach Lake Ontario

Have you ever wondered how a large ship can navigate from Lake Ontario to other Great Lakes, given the obstacle of Niagara Falls?

The key to this puzzle is the Welland Canal, a man-made route built to bypass the Niagara Falls and connect the St. Lawrence Seaway to the Great Lakes system. The Welland Canal allows ships to travel between Lake Ontario and Lake Erie, effectively bypassing the natural barrier.

Overcoming Niagara Falls with the Welland Canal

The Welland Canal is a 27.5-mile (44.3 km) long waterway that consists of 8 Locks, connecting St. Catharines on Lake Ontario to Port Colborne on Lake Erie. This bypasses Niagara Falls and allows ships to travel between these two lakes without encountering the obstacle.

Understanding the Lock System

To fully comprehend the process, it is essential to look at the lock system in the Welland Canal. The top map illustrates the various locks required to navigate through the St. Lawrence Seaway, while the diagram below depicts the Welland Canal's layout and the locations of the 8 locks.

The bottom diagram provides a profile view, showcasing the elevational changes. Notably, the elevation difference between Lake Erie and Lake Ontario is approximately 99.3 meters (305.1 ft.). This significant height difference necessitates the use of 8 locks to safely transport ships between these lakes.

The Lock System in Detail

The Welland Canal operates with 8 locks, each serving a specific purpose in adjusting the water levels to ensure safe passage. These locks work sequentially to raise or lower the ships by small increments, accommodating the considerable elevation change.

For a better understanding, the lock system can be visualized as a step-by-step process, where each lock functions to lift or lower the ship by a predetermined amount. This ensures that the ship always remains at the appropriate water level at each point of its journey, overcoming the natural elevation difference between the lakes.

Using the Welland Canal for Navigation

Ships traveling from Lake Erie to Lake Ontario, or vice versa, must follow the route through the Welland Canal, which is often referred to as the 'canal of canals.' This network of waterways and locks is meticulously designed to handle the traffic of sizable vessels, ensuring that they can navigate safely and efficiently without the need to portage around the falls.

In summary, the ability of ships to navigate from Lake Ontario to other Great Lakes is made possible through the strategic engineering of the Welland Canal, a solution that has been in use for over a century, facilitating the movement of goods and facilitating transportation in the region.
