Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken.
Locks enable water vessels to move from one section or body of water at one level to another section of water at another level through river and canal waterways.
Locks allow a canal to go up and down hills. If there were no locks in the Panama canal, the Atlantic and Pacific oceans couldn't flow into each other, because there are hills in between. The tropical marine life of each ocean, at either end, consists almost entirely of different species.
Geographically, the oceans that Panama Canal connects with are not at the same level; the Pacific Ocean lies a little higher than the Atlantic Ocean. This difference in the sea level requires ships to get up over the terrain of Panama- up to 26 meters above sea level- in order to reach the other end of the canal.
The canal needs locks in order to raise ships high enough to cross the Continental Divide. The ships traverse man-made Gatun Lake about 80 feet above sea level and are then lowered to head downward on the other side.
The Kieldrecht lock at the Belgium's Port of Antwerp has been inaugurated today when H.M. King of Belgium officially opened this, now the world's largest lock, by pressing the button to symbolically mark the inauguration.
Tools Used to Build the Erie Canal
The process of excavation for construction of the Erie Canal. Much of the planned route for the Erie Canal ran through thickly forested wilderness and the early teams of laborers had nothing more than axes, pickaxes and shovels to fell countless trees and uproot giant stumps.
The cill is a protruding stone or concrete ledge at one end of the lock chamber. It's usually located behind your boat when you are coming 'down' in a lock. It is important to avoid the cill when you are in the lock.
Opened in 2016, the third locks offer a grandiose upgrade from the original 1914 passage. Thanks to the Chinese, we have the pound lock—the common type of gate-operated lock now used all over the world. Locks as we know them today can almost all be traced back to China's Grand Canal and its 10th Century innovations.
The invention of both canals and canal locks can be traced to Leonardo da Vinci. Leonardo was a genius, who had many ideas that were not understood until centuries after he died. He drew designs for canal locks in his notebooks as far back as the fifteenth century.
There are paddles on locks which are raised and lowered to control the water flow and alter the level. The cill is a large raised ledge at the top end of the lock which the top gate shuts against. So, how does a lock work on a canal?
The Erie Canal is drained every year to allow repairs and maintenance over the winter.
The complete NYS Canal System is 524 miles long and consists of four canals– the Erie, Oswego, Champlain and the Cayuga-Seneca. All four canals are contemporary and fully operational.
Weighting 41 mg, with a height of 3 mm and a circumference of 1 cm, the small gold lock got a world record certificate from the World Record Association.
In Britain, the very first lock flight was built on the Sankey Canal in 1757. There were pound locks on the Exeter Ship Canal in the 16th Century, although this was more of a river navigation.
(See photo on right.) The deepest lock in the world is Oskemen Lock, bypassing a hydro-electric dam on the River Ertis in Kazakhstan, with an incredible rise of 138 ft (42m).

The Erie Canal is a 363-mile waterway that connects the Great Lakes with the Atlantic Ocean via the Hudson River in upstate New York. The channel, which traverses New York state from Albany to Buffalo on Lake Erie, was considered an engineering marvel when it first opened in 1825.
The purpose of the locks and dams is to create a series of steps which river tows and other boats either climb or descend as they travel upstream or downstream.
