Turfgrass Consumptive Use: Flagstaff, Arizona

Irrigation of turfgrass is an issue of growing concern in northern Arizona cities and towns as population growth places increasing demands on limited water supplies. Understanding the water requirements of turfgrass is essential if we are to improve irrigation management and better plan for future urban growth. Consumptive use (CU) tables and curves that provide average rates of turfgrass water use (evapotranspiration; ETT) supply this much needed information. The original bulletin on turfgrass consumptive use for the Flagstaff area (Brown and Albrecht, 2005) was developed in conjunction with the University of Arizona TRIF1 Water Sustainability Program that also funded the installation and operation of an automated weather station to improve future estimates of turfgrass CU. This bulletin provides revised estimates of turfgrass CU developed from data sets collected by this weather station.
