The Soo Locks, located between Lake Superior and Lake Huron, are one of North America's most significant engineering feats and a vital component of the Great Lakes navigation system. This series of locks allows ships to traverse the difference in water levels between the two lakes—approximately 21 feet (6.4 meters). In this article, we will explore the importance, function, and history of the Soo Locks.

What Are the Soo Locks?

The Soo Locks are a set of navigational locks situated in Sault Ste. Marie, Michigan. Their primary purpose is to facilitate the movement of large vessels, allowing them to travel from the higher waters of Lake Superior down to the lower waters of Lake Huron and vice versa.

Why Are the Soo Locks Important?

Economic Impact: The Soo Locks are critical for trade, handling millions of tons of cargo annually. They are vital for transporting iron ore, coal, and grain, which are essential for the economy of the Great Lakes region.
Safety: The locks provide a safe passage for vessels by controlling the water levels and reducing the risk of flooding or grounding, which could occur if ships were to navigate the rapids of the St. Marys River without the locks.
Recreation: Beyond their commercial importance, the Soo Locks are a popular tourist destination. Visitors flock to watch massive freighters pass through the locks, which can be an awe-inspiring sight.

How Do the Soo Locks Work?

The operation of the Soo Locks can be likened to a giant water elevator. Here’s a step-by-step breakdown of the process:

Arrival: A vessel arrives at the lock, and a crew member signals that the lock is ready to accept them.
Entry: The vessel enters the lock chamber, and the lock gates close behind it.
Water Adjustment: Water is either added or drained from the chamber to raise or lower the vessel to the corresponding water level.
Departure: Once the water level is equalized, the outer gates open, allowing the vessel to exit safely.

Types of Locks

The Poe Lock: The largest and most used, accommodating the largest vessels.
The MacArthur Lock: Smaller but essential for other vessels.
The Davis Lock: Mainly used for recreational traffic.

A Brief History of the Soo Locks

The concept of the Soo Locks dates back to the early 19th century. Here are some key milestones:

1855: The first lock, known as the “Old Lock,” was completed, but it was soon found inadequate for the growing needs of shipping.
1896: The completion of the current Poe Lock, which significantly improved shipping efficiency.
1959: The construction of the MacArthur Lock, providing additional capacity and redundancy.

Visiting the Soo Locks

If you're considering a visit to the Soo Locks, here are some tips to enhance your experience:

Best Time to Visit: Late spring through early fall is ideal for viewing the ships as they navigate the locks.
Viewing Locations: The visitor center offers an excellent vantage point, and there are several parks along the riverbank.
Tours: Consider taking a boat tour that allows you to experience the locks from the water.

Conclusion

The Soo Locks are not just a marvel of engineering; they are the lifeline of commerce for the Great Lakes region. Whether you are a shipping enthusiast, a historian, or a curious traveler, a visit to the Soo Locks offers a unique opportunity to witness a vital part of North American trade in action.
