Natural sources of salinity in the Brazos River, Texas with particular reference to the Croton and salt Croton Creek basins Natural sources of salinity in the Brazos River, Texas with particular reference to the Croton and salt Croton Creek basins
The average daily load of the Brazos River at Possum Kingdom Reservoir is about 2,800 tons of dissolved solids, of which 1,000 tons is chloride. More than 85 percent of the chloride load is contributed by the Salt Fork Brazos River, and more than 50 percent of the chloride load of the Brazos River originates from salt springs and seeps in Croton and Salt Crotdn Creeks, which are...

Ground-water geology of Karnes County, Texas Ground-water geology of Karnes County, Texas
The exposed rocks and those underlying Karnes County dip toward the Gulf of Mexico at average rates ranging from 20 to more than 200 feet per mile. The oil fields are on structures associated with faulting; the effect of faulting on the occurrence of ground water has not been determined. The principal water-bearing formations, from oldest to youngest, underlying the county are the...

Effects of drought in central and south Texas Effects of drought in central and south Texas
The effects of drought upon ground-water storage and discharge, and upon streamflow, vary tremendously in the central third of Texas (the area from the Panhandle to the Gulf of Mexico). Extremes are represented by (a) the Llano Estacado, where the drought had negligible effect upon ground-water resources, which are being progressively depleted by pumping for irrigation; and (b) the...

Geology and ground-water resources of Hays County, Texas Geology and ground-water resources of Hays County, Texas
The Edwards limestone of Early Cretaceous age is the chief aquifer for San Marcos Springs and about 160 other springs and wells in Hays County, along the Balcones fault zone in South-central Texas. Hays County is underlain by a basement of Paleozoic rocks; and in the southeastern part of the county the Hosston and Sligo formations of Early Cretaceous age, correlative with the Coahuila...
