Estimated crop irrigation water use withdrawals in Butler Valley Groundwater Basin, Arizona for 2023
Observations of irrigated agricultural land within the Butler Valley Groundwater Basin in Arizona. Digitized field boundaries were used to locate crops for in situ verification twice in 2023; crop verification occurred first on May 10th and again on Sept 28th. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program County Mosaic 2023 imagery for Arizona and supplemented with Sentinel2 imagery collection accessed via the European Space Agency Copernicus Browser (https://browser.dataspace.copernicus.eu/). Satellite images were also used to identify the length of the growing season and crop condition. Water withdrawals were calculated using the modified Blaney-Criddle model of calculating consumptive use (U.S. Bureau of Reclamation, 1992 appendix A) using crop coefficients from Doorenbos and Pruitt (1975), the number of acres with active crops, crop condition, and irrigation system efficiency. The withdrawal equation was modified from "Water withdrawals for irrigation, municipal, mining, thermoelectric-power, and drainage uses in Arizona outside of active management areas, 1991-2000" (Tadayon, 2005) to account for variations in water application.
