The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Washita River aquifer by using MODFLOW-2005 (Harbaugh, 2005) with the Newton formulation solver (MODFLOW-NWT). The 1973 Oklahoma Groundwater Law requires that the OWRB conduct hydrologic investigations of the State’s aquifers to determine the maximum annual yield (MAY) for each groundwater basin. The MAY is defined as the total amount of fresh groundwater that can be annually withdrawn while allowing a minimum 20-year life of that groundwater basin. For alluvium and terrace groundwater basins, the life requirement is satisfied if, after 20 years...
This model has been superseded by an updated version of the model. The new model can be found at: https://doi.org/10.5066/P99KJ1U1, https://doi.org/10.5066/P9FTZ5RW, https://doi.org/10.5066/P9NBWLYX, https://doi.org/10.5066/P97XBULI, https://doi.org/10.5066/P980EHWV, https://doi.org/10.5066/P95XLBB5, https://doi.org/10.5066/P9ICSZWF, https://doi.org/10.5066/P96LJ01V, and https://doi.org/10.5066/P9IZRO3V. A three-dimensional groundwater flow model (MODFLOW200-FMP1_1) of the Central Valley in California was developed to aid water managers in understanding how water moves through the aquifer system, to predict water-supply scenarios, and to address issues related to water competition. The USGS Groundwater Resources...
