Waterford Flight

Waterford Flight is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Waterford Flight rather than just read about it. In short: The Waterford Flight is a set of locks on the Erie Canal in Waterford, New York. Erie Canal Locks E-2 through E-6 make up the combined flight at Waterford, which lifts vessels from the Hudson River to the Mohawk River, bypassing Cohoes Falls.

Key takeaways

Waterford Flight belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Waterford Flight to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Waterford Flight from memory before moving on to harder problems.

Reference excerpt

The Waterford Flight is a set of locks on the Erie Canal in Waterford, New York. Erie Canal Locks E-2 through E-6 make up the combined flight at Waterford, which lifts vessels from the Hudson River to the Mohawk River, bypassing Cohoes Falls. Built in 1915, the Waterford Flight is still in use today as part of the New York State Canal System, which is open to public and commercial traffic. The Waterford Flight is the series of locks with the highest elevation gain (169 feet (52 m)) relative to its length (1.5 miles (2.4 km)) for any canal lock system in the United States.

Planning The original route of the Erie Canal bypassed Cohoes Falls to the south through the city of Cohoes. At the turn of the century, plans for an enlarged Erie Canal were being drawn up to accommodate more traffic and larger vessels. However, instead of constructing canals from scratch like had been done previously, the plan proposed "canalizing" the local rivers. For the plan near Cohoes, it involved routing a channel from the Mohawk River north of Cohoes Falls directly to the Hudson River at Waterford. Traffic would then flow directly from the Hudson to the Mohawk via the Waterford Flight and completely bypass the old canals from Albany to Cohoes. The Troy Federal Lock and Dam would serve as the unofficial start of the Erie Canal, with the first lock of the Waterford Flight being the official beginning, hence it being named E-2 to this day.

Construction Construction of the Waterford Flight began in 1905 and took 10 years to complete. The 5 massive locks dwarfed the previous iterations and were mandated to be 328 feet (100 m) long, 45 feet (14 m) wide, and 12 feet (3.7 m) deep. These dimensions became the standard on the Barge Canal System and have been maintained to this day. In addition to the locks, there are two large guard gates at the northern end of the flight. These gates can be lowered to block additional flow of water from the Mohawk River through the locks to prevent damage during floods. The locks have undergone periods of major restoration in recent decades, including replacement of lock doors and resurfacing of the concrete within the locks themselves.

Today

Today, the Waterford Flight is in use and is managed by the New York State Canal Corporation. The site of the Waterford Flight is also home to Lock 6 State Canal Park, which follows the length of the canal between the Hudson and the Mohawk and allows public access to the locks and a boat ramp at the Northern end. The set of locks was designated as a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 2011.

Worked examples

Example 1 — a first encounter with Waterford Flight

Start with the simplest possible case. Write down what Waterford Flight claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Waterford Flight before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Waterford Flight ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Waterford Flight

In research: Waterford Flight appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Waterford Flight in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Waterford Flight is common in secondary-school and first-year university syllabi. It links to neighbouring topics Erie Canal, Historic Civil Engineering Landmarks, Locks of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Waterford Flight outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
