Estimated Monthly Water Use for Irrigation by 12-Digit Hydrologic Unit in the Conterminous United States for 2015

This data release contains the output of the Irrigation Water Use Estimation Disaggregation and Downscaling Model (IWUEDD) along with the scripts and data resources required to replicate the output results. The IWUEDD is used to estimate monthly irrigation withdrawals and consumptive use for each 12-digit hydrologic unit code (HUC 12) subwatershed in the conterminous United States. The HUC 12-level estimates are separated into groundwater (GW), surface water (SW), groundwater and surface water combined (TW), and consumptive use (CU). The IWUEDD developed monthly estimates by disaggregating and downscaling previously published annual county-level irrigation withdrawal and consumptive use data complied as part of the National Water Use Science Project, National Water Census as presented in U.S. Geological Survey data release, “Estimated use of water in the United States county-level data for 2015” (Dieter and others, 2018).
