An irrigation canal is a waterway, often man-made or enhanced, built for the purpose of carrying water from a source such as a lake, river, or stream, to soil used for farming or landscaping.
It can be dug into the ground and then filled with water, or an existing stream can be widened in a process called “canalization,” and diverted as appropriate to provide maximum efficiency.
One of the difficulties with irrigation canals is providing a reliable flow of water.
