  • An irrigation canal like this is a big ditch to move water from a river to near farm fields. Without the extra water taken from the river, there wouldn’t be enough water in the soil for crops to grow in the area.

    Being a big ditch open to the sky, the hot sun and dry air make a bunch of the irrigation water evaporate before it even gets to the field. So we went to all the effort of taking water out of the river just to waste it humidifying the nearby air.

    Why did we do it in the first place? Because it’s way easier and cheaper to dig a ditch than to lay a big pipe, and I don’t know if the US had any other water-delivery tech at the right scale when these were built.
