There is today an urgent need for information on how to distribute irrigation water uniformly over land surfaces. Land and water are no longer cheap. Prices of the better irrigated lands in Utah range from $200 to $400 or more per acre, whereas dry farm lands are worth less than $100. Water stock which formerly sold at $25 per share now costs $100, or more. Storage water in the newer reservoirs costs from $30 to $50 per acre-foot, an amount equivalent to $9,000 or more for a full water right to irrigate 100 acres. Because of these high costs of land and water it is more and more essential to apply irrigation water efficiently.
