Soil-water-balance model and data used in the hydrogeologic investigation, framework, and conceptual flow model of the Antlers aquifer, southeastern Oklahoma, 1967–2022

This archive contains the data used to (1) summarize the hydrogeology and update the hydrogeologic framework of the Antlers aquifer in southeastern Oklahoma, and (2) develop a conceptual groundwater-flow model and water budget to estimate recharge to the Antlers aquifer during 1980–2022 as part of a hydrologic investigation (the model documentation report is available at https://doi.org/10.3133/sir20255013). The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a soil-water-balance (SWB) model of the Antlers aquifer in southeastern Oklahoma. The soil-water balance (SWB) model was used to simulate groundwater flow and estimate recharge to the Antlers aquifer. The input data and resulting output recharge data files are contained herein. Input data for the SWB model are precipitation, air temperature, soil-water storage capacity, hydrologic soil group, surface-water flow direction, and land-cover type. Data used in a multiple well aquifer pumping test, slug tests, groundwater-quality analysis, base-flow index estimation, and an analysis of groundwater use in the Antlers aquifer are provided. All associated data files are included in the ancillary folder of this data release.
