Irrigation is the very important step in the haying process since the average precipitation is 10-12 inches per year. Without the extra water, the crop plants would not produce enough to feed the herd through the winter.
Flood irrigation is the historic method of irrigating, where water is carried in a series of ditches and then damned up to flow over an area of the fields. The extra water flows downhill to another catch ditch, which carries it on across the field. These "sets", or where the dams are placed and therefore, which areas are flooded, need to be changed daily.
There are four historic ditches still in use, maintaining the historic landscape and historic water rights. The oldest of these and closest to the ranch buildings, is the Kohrs-Manning Ditch, dug in 1870. The Kohrs Big Ditch and the Taylor Ditch have been in use since 1885 and Westside Ditch since 1887. These historic main ditches total 9 miles in length. This network of ditches allows for the correct amount of water to be delivered throughout the growing season. How the grasses are irrigated influences how much hay is available to harvest for winter feed.
