III. CONSUMPTIVE IRRIGATION REQUIREMENT
Calculated Consumptive Irrigation Requirement of Crops at Wyoming Weather Stations
Variability of Consumptive Irrigation Requirement
The map following this page - Average Seasonal Consumptive Irrigation
Requirement for Grass - shows the variation of seasonal consumptive
irrigation requirement for the most widely grown irrigated crop in Wyoming.
Lawn grass and irrigated pastures are not always considered to be irrigated
crops, but certainly grass consumes irrigation water. Thus, the values
indicated on the map have a value to city dwellers as well as farmers and
ranchers.
Use of Data The calculated values contained herein should be useful to planners and conservationists for a multitude of purposes. Estimates of the amount of irrigation water consumed in various areas of Wyoming can be made. The data should assist planners in the design of both large and small irrigation projects. If diversions for irrigation and the areas irrigated are known, the irrigation efficiency can be calculated. Diversion requirements can be determined if irrigated areas and irrigation efficiency are known or estimated.
