Groundwater Resources in the Llano Uplift Crystalline Massif Llano and Mason Counties, Texas Mishal Al-Johar November 24, 2009 CE 394K GIS in Water Resources

The Llano Uplift is characterized by GEOLOGY: Igneous and metamorphic crystalline granite, gneiss, and schist CLIMATE: Semi-arid LANDUSE: Rural ranch land SURFACE WATER: Several large, man-made reservoirs Smaller streams GROUNDWATER: Low porosity crystalline rocks Permeable zones occur in fractures Relatively low groundwater storage THE CRYSTALLINE MASSIFF IN THE LLANO UPLIFT IS NOT “OFFICIALLY” A MINOR AQUIFER DOES IT DESERVE TO BE?
