This dataset describes irrigation water use in Kansas in 2016. Volumes of water used, irrigated area, and irrigation application depths are provided for three sets of subareas: (1) Irrigation water use analysis regions that include Groundwater Management Districts (GMDs) with the areas outside of GMDs divided into eastern, central, and western Kansas; (2) Regional Planning Areas (RPAs), which are 14 areas determined by the Kansas Water Office based on hydrologic and administrative boundaries, each with a set of goals outlined in the Kansas Water Vision (https://kwo.ks.gov/water-vision-water-plan/water-vision); and (3) the 105 Kansas counties. Volumes of water used, irrigated area, and application depths are also presented for the subareas by crop type and by irrigation system type. Volumes of water used, irrigated area, and application depth are also provided for ditch companies and irrigation district conveyances.
