Total Applied Surface Water and Groundwater Irrigation Data from Four Areas to Support Analysis for Estimating Irrigation Consumptive Use for the Conterminous United States

This digital dataset contains irrigation applications and consumptive use at the agricultural-field scale (average 173 acres) and twelve-digit watershed scale (HUC12) for four regions in the conterminous United States representing calendar years 2000-2020. Agricultural field-scale irrigation depths of applied groundwater and surface water for selected agricultural fields were compiled from local and state agencies for Pajaro Valley, California, Snake River, Idaho, Colorado River, Colorado, and the Mississippi Alluvial Plain. To ensure accurate irrigation amounts for agricultural fields, only data that could be directly (1-to-1) tied with surface water and groundwater points of diversion and agricultural field places of use were used. Agricultural field-scale data were aggregated to HUC12 scale to compute consumptive use and compare with consumptive use reported in Martin and others (2023).
