More than 11,500 well records, such as geophysical logs, drilling descriptions, and published hydrogeologic framework information, were evaluated to help characterize the framework of hydrogeologic units in and near Gaines, Terry, and Yoakum Counties, Texas. Additional geophysical data were collected to improve the spatial coverage across the study area and to reduce uncertainty with regard to hydrogeologic unit extents. The evaluation of existing data plus the collection of new geophysical data provided that basis for developoing a refined understanding of how the saturated thickness of the Ogallala and Edwards-Trinity aquifers vary throughout the study area.
This Data Release contains various types of hydrologic and geologic data from the Pecos River Basin during1900–2015, including water-quality data compiled and synthesized from various sources (including data from water-quality samples collected by the USGS in 2015 from 26 sites), streamflow gain-loss data collected by the USGS in 2015 and historical streamflow gain-loss data compiled from the literature, the horizontal extent of and depth to the base of the 16 geologic and hydrogeologic units that underlie the study area, and geospatial data collected by the USGS. The data were used to complete a detailed salinity assessment of the Pecos River from Santa Rosa Lake, New Mexico to the Confluence of the Pecos River...

This data release contains waterborne self-potential (WaSP) and surface-water (SW) temperature, conductivity, and specific conductance data measured by the U.S. Geological Survey (USGS) along a 43.2-kilometer (km) long profile in the Elm Fork of the Trinity River upstream from the Dallas, Texas, metropolitan area. The WaSP data were measured from a kayak during January 25–27, 2022, along three survey segments between Lewisville Lake Dam and Frasier Dam Recreational Area. The first segment was surveyed on January 25, began a short distance downstream from Lewisville Lake Dam, and ended about 19.2 river-km downstream, a few meters upstream from Carrollton Dam in McInnish Park. The second was surveyed on January 26,...

In cooperation with the Llano Estacado Underground Water Conservation District (LEUWCD), the Sandy Land Underground Water Conservation District (SLUWCD), and the South Plains Underground Water Conservation District (SPUWCD), the U.S. Geological Survey (USGS) compiled historical geophysical and geochemical data in Gaines, Yoakum, and Terry Counties, Texas, and collected additional data where gaps were evident to assist with building a conceptual hydrogeologic model of the Gaines, Yoakum, and Terry Counties region. The compiled historical data includes all data available from predevelopment (pre-1945) through present day. For this study, predevelopment is considered everything prior to 1945 when the large-scale groundwater...
This Data Release contains various types of hydrologic and geologic data from the Upper Rio Grande Focus Area Study from 1921-2017, including groundwater-level measurement data compiled and synthesized from various sources, water-level altitude and water-level change maps developed from the water-level measurement data every 5 years from 1980-2015, and the horizontal extent of 13 alluvial basins in the Upper Rio Grande Basin
