Irrigation Water Use map, monthly averages 2009-2020 by watershed
Detailed Description
This model computes the amount of crop irrigation withdrawals each month over the period from 2000 to 2020 for all subwatersheds (12-digit Hydrologic Unit Codes or HUC12s) in the conterminous United States (CONUS).
Crop irrigation withdrawals refer to water removed from a groundwater or surface-water source to produce agricultural crops. In this model, crop irrigation withdrawals are calculated by combining modeled irrigation consumptive use, irrigation efficiencies, and source-water proportions.

Irrigation Water Use
Irrigation water use includes water that is applied by an irrigation system to sustain plant growth in agricultural and horticultural practices. Irrigation also includes water that is used for pre-irrigation, frost protection, chemical application, weed control, field preparation, crop cooling, harvesting, dust suppression, and leaching salts from the root zone.
