Geohydrology and Numerical Simulation of Groundwater Flow in the Central Virgin River Basin of Iron and Washington Counties, Utah (TP-116 OFP) Other Scale Geologic Maps as well as scales forBy: V. M. Heilweil, G. W. Freethey, C. D. Wilkowske, B. J. Stolp, and D. E. Wilberg Because rapid growth of communities in Washington and Iron Counties, Utah, is expected to cause an increase in the future demand for water resources, a hydrologic investigation was done to better understand ground water resources within the central Virgin River basin. This study focused on two of the principal ground water reservoirs within the basin: the upper Ash
