The USGS, in cooperation with the City of Summerset, South Dakota, developed a Soil-Water Balance (SWB) model of the alluvial aquifer in north Summerset to estimate recharge and potential evapotranspiration volumes and rates for 2017-2019. The model area included the north part of the city of Summerset in west South Dakota along the east range of the Black Hills. The SWB model output can be used for groundwater flow models, water budget calculations, and to study the effects of precipitation variations on groundwater levels. The output for the model was used to estimate recharge and potential evapotranspiration for budget calculations. The model is uncalibrated but the output could be calibrated as an input for another model, such as a groundwater flow model.

This USGS data release contains all of the input and output files for the model described in the associated model documentation report (https://doi.org/10.3133/sir20205097).
