ERCOT Reservoir Watershed Delineations and Inflow Scenarios

This dataset includes daily runoff totals for historical (reanalysis) and future (GCM simulations) climate. The scenarios are generated for upstream watersheds of 44 reservoirs that supply water for thermal plant cooling throughout the Electric Reliability Council of Texas (ERCOT) power grid region. These data are derived from 1/24 degree gridded CONUS-scale hydrological simulations. Runoff projections are masked to delineated watershed areas (included as shape files) and summed across grid cells within the target watershed. These data may be aggregated to monthly scale to produce unregulated inflow scenarios for ERCOT reservoirs. Reservoir attributes and storage records are included in a supplementary excel spreadsheet. Please see README.txt for further details.
