The U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, constructed a finite-difference numerical groundwater-flow model of the Washita River alluvial aquifer using MODFLOW-2005 with the Newton formulation solver (MODFLOW-NWT). The 1973 Oklahoma Water Law (82 OK Stat § 82-1020.5) requires the Oklahoma Water Resources Board to conduct hydrologic investigations of the State's aquifers to support a determination of the maximum annual yield (MAY) for each groundwater basin. A permanent MAY and EPS have not been established for the Washita River alluvial aquifer; thus, the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, conducted calibration and simulations...
In 2018 The U.S. Geological Survey, in cooperation with the U.S. Bureau of Reclamation and the Oklahoma Water Resources Board, published a calibrated numerical groundwater- flow model and associated model documentation report that evaluated the effects of potential groundwater withdrawals on groundwater flow and availability in the Rush Springs aquifer in western Oklahoma. The results of groundwater-availability scenarios run on the calibrated numerical groundwater-flow model could be used by the Oklahoma Water Resources Board to evaluate the maximum annual yield of groundwater from the Rush Springs aquifer in Oklahoma. A conceptual groundwater-flow model is a simplified description of the major inflow and outflow...
