Weiskel water use regime calculations for hydrologic regions of the Conterminous United States

This data release contains the output from the analysis of the intensity to human water budget modification following the standards of Weiskel and others (2007) according to hydrologic regions of the conterminous United States (CONUS) by Van Metre and others (2020).

Initial water budget data were produced by Martinez and others (2026) by combining the monthly water balance from water supply and human consumptive uses for CONUS from 2010-2020 by 12-digit hydrologic unit code (HUC12) available through the Mainstem Rivers v2 (Blodgett 2022). Water supply was calculated from two physically based hydrologic models, and consumptive water use was calculated from three separate national models for agricultural irrigation, thermoelectric power generation, and public supply. Water budgets were routed through the surface-water flow network (to allow for upstream consumptive uses to affect downstream water availability) and used to determine potential water limitations for human populations and fish species. Key variables were exctracted according to total withdrawal, consumptive uses, and estimated returns to the water budget (total withdrawals - consumptive uses) for irrigation, public supply, and thermoelectric power supply generation uses.

This data release contains a data dictionary and two tabular datasets in comma delineated format (.csv), covering regional summarizations of variables used in this Water use Regime analysis aggregated by hydrologic region and aggregated hydrologic regions. They are:

data_dictionary.csv - A data dictionary containing entity and attribute information about variable names, descriptions, data types, and ranges for easy access to end users.
Weiskel_water_regime_data_conus_huc12.parquet - Dataset containing values in depth (mm) for surface water supply and consumptive and total withdrawal water use components used in figures and descriptions of Weiskel inspired water use regimes. Dataset contains all HUC12s contained within CONUS, prior to any regional summarizations. All data are based on the mean value from 2010-2020 for all HUC12s.
Weiskel_water_regime_data_HR.csv - Dataset containing values in depth (mm) for surface water supply and consumptive and total withdrawal water use components used in figures and description of Weiskel inspired regional water use regimes. All data are based on the mean value for all HUC12s contained within each Van Metre hydrologic region.
Weiskel_water_regime_data_AR.csv - Dataset containing values in depth (mm) for surface water supply and consumptive and total withdrawal water use components used in figures and description of Weiskel inspired regional water use regimes. All data are based on the mean value for all HUC12s contained within the four aggregated regions of the original Van Metre hydrologic regions.
