A plan and side view of a generic, empty canal lock. A lock chamber separated from the rest of the canal by an upper pair and a lower pair of mitre gates.The gates in each pair close against each other at an 18° angle to approximate an arch against the water pressure on the "upstream" side of the gates when the water level on the "downstream" side is lower.

In order to allow ships to move freely, the eastern end of the dam contains a lock, commonly called the Federal Lock or (on some charts and publications) the "Troy-US Lock." The lock, which was opened in 1916, has a single chamber and is 520 feet (160 m) long, 45 feet (14 m) wide, 17 feet (5.2 m) deep, and has a lift of approximately 14 feet (4 ...
The main lock at Wilson Dam is 110 feet (34 m) wide by 600 feet (180 m) long. [7] The lock lift is 94 feet (29 m). [7] It is the highest single lift lock east of the Rocky Mountains. [5] An auxiliary lock has two 60 feet (18 m) wide by 300 feet (91 m) long chambers that operate in tandem. Over 3,700 vessels pass through Wilson Dam's locks each ...
