Canals are artificial waterways that are constructed to provide a new path of travel for vessels ( as opposed to improving a natural waterway along its current course ).

* The Cornwall and Chambly Canals are opened.

Canals are usually fed by diverting water from streams and rivers into the upper parts of the canal, but if no suitable source is available, a pumping station can be used to maintain the water level.

Canals, siphons, and more dams are used throughout the Columbia Basin, supplying over 600, 000 acres ( 2, 400 km² ) of farm land.

Note: because it's no longer generally known nor readily discernible that the river sections between the Pannerden and Bijland Canals and between the Bijland Canal and the original fork actually are part of river Waal, they nowadays are generally called " Rijn " ( Rhine ).

Canals were important for industrial development.

Canals have found another use in the 21st century, as easements for the installation of fibre optic telecommunications network cabling, avoiding having them buried in roadways while facilitating access and reducing the hazard of being damaged from digging equipment.

The department of Earth was to be in charge of Agriculture and the agricultural sciences, Fire was to be in charge of the Military, Water was the department of the Canals and waterways while Air seemed to have responsibility for everything else.

Canals dug for the oil and gas industry also allow storms to move sea water inland where it damages swamps and marshes.

The Sacramento Canals Division of the CVP takes water from the Sacramento River much farther downstream of the Shasta and Keswick Dams.

A second canal, the Contra Costa Canal, captures freshwater near the central part of the delta, taking it southwards, distributing water to the Clayton and Ygnacio Canals in the process, and supplying water to Contra Loma Dam, eventually terminating at Martinez Reservoir.

The rest of the waterway to Port Dundas was converted into a culvert to maintain the water flow, and much of it now lies beneath the M8 motorway which was constructed along its path in the early 1970s ; the culvert remains under the jurisdiction of Scottish Canals ( as successor to British Waterways ) because of its function as a feeder to the Forth and Clyde Canal.
