Compilation of Time-Domain Electromagnetic Surface Geophysical Soundings, Historical Borehole Characteristics, Water Level, Water Quality and Hydraulic Properties Data Throughout Gaines, Yoakum, and Terry Counties in Texas, 1929-2019

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 extractions [...]
