Water budget results for a water availability assessment across the conterminous United States for water years 2000-2020

This data release contains results from a simple monthly water budget that includes water supply and consumptive use for thermoelectric, irrigation, and public supply for 12-digit Hydrologic Unit Codes (HUC12) across the conterminous United States for water years 2000-2020. These results were produced using an analysis pipeline that ingests water supply, consumptive use, and routing information and accumulates and routes the water balance through the HUC12 network (Martinez and others, 2064; https://doi.org/10.5066/P13TPXFX). Water budget results also include an assessment of supply and use imbalances within the context of historical climatic conditions to calculate a surface water supply and use index and when considering a range of environmental flow allocation methods.

This data release contains six files:

- water_budget_sui_ensemble.csv.gz and water_budget_sui_ensemble.parquet: Water budget results with NHM and WRF-Hydro supply averaged (ensembled) for each HUC12 and month.
- water_budget_sui_nhm.csv.gz and water_budget_sui_nhm.parquet: Water budget results using only the NHM for water supply estimates.
- water_budget_sui_wrfhydro.csv.gz and water_budget_sui_wrfhydro.parquet: Water budget results using only WRF-Hydro for water supply estimates.
The CSV and parquet file pairs contain identical data in different formats (.csv.gz for broad accessibility; .parquet for optimized handling of large datasets).
