How do Erie Canal locks work?
Erie Canal locks consist of two sets of Miter-V gates to form the chamber and contain the water , underground tunnels for the water to flow in or out and tunnel valves (they resemble guillotines) to open or shut the water flow through the tunnels. The lock chamber and floor is made of concrete.
What is a navigable lock?
A lock is a part of a navigable waterway system that makes a water “channel” deep enough for vessels to use. The lock is like a big chamber with gates at each end. They have lock gears which empty or fill the chamber with water.
What are the different types of lock gates?
Different types of locks
- Single locks. Single locks consist of one lock gate and are the most straightforward to use.
- Broad locks. Double the width of a single or narrow lock allowing two narrowboats to go through together, or one wide boat.
- Double locks.
- Stop locks.
- Staircase locks and flights.
How do the Panama locks work?
The canal has a water lock system that acts like a massive elevator. When ships enter the locks, they’re raised by water from the lake. Each lock raises the ships until they’re 85 feet above sea level. The ship is then lowered by the locks to sea level.

Why are there locks on a canal?
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level.
How many canal locks are there?
There are twelve locks in total. A two-step flight at Miraflores, and a single flight at Pedro Miguel, lift ships from the Pacific up to Gatun Lake; then a triple flight at Gatun lowers them to the Atlantic side.
What would happen if the Panama Canal had no locks?
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.
Why does Erie Canal have locks?
Lock. Locks are elevators for boats, lifting and lowering them as they travel along the waterway.
What is the highest lift lock in the world?
The Peterborough Lift Lock
The Peterborough Lift Lock was designated a national historic site of Canada because: it is the highest hydraulic lift lock in the world. The heritage value of this site resides in its surviving physical attributes, and the fact that it was, and remains, an engineering achievement of national and international renown.
How do locks work on a canal?
This lifts the boat up to a higher canal level, or if going the other way lowers the boat down to a lower level if you are letting water out of the lock. A lock consists of a lock chamber which is brick, stone or metal and holds the water. To allow boats to get in and out, and to keep the water in, there are gates at each end of the lock.
Who operates the locks on a canal boat?
On the U.K. canal systems, your crew will operate the locks yourselves, perhaps with the help of crews from other boats. It can be a nice social occasion.
Are there any lock simulations on the canals?
Once you’re flummoxed by the staircase locks, the same site also has a single lock simulation available. Another relative rarity on the canals are “side ponds” associated with locks. The side ponds allow a full lock cycle (from full to empty to full again) to be done WITHOUT using a whole lockfull of water.
How are the locks operated on river navigations?
On river navigations in the U.K. (e.g. the Thames), and on many European canals, the locks are operated by lock keepers. Lockkeepers in France only require a very small tip for their services.
