Data

The U.S. Geological Survey, in cooperation with the City of Brownsville, Texas, collected bathymetric data for selected resacas (former distributary channels and oxbow lakes of the Rio Grande that are now cut off from the river) in the Brownsville, Texas area during September 2021 through April 2023. Bathymetric survey points were collected using real-time network Global Navigation...

This data release contains self-potential (SP) map data, two-dimensional electrical resistivity tomography (ERT) data, and time-lapse SP-monitoring data measured within the thermal springs discharge area of Hot Springs National Park in Hot Springs, Arkansas, in addition to the geospatial coordinates of each geophysical measurement and photographs of the reconnaissance and monitoring...

This data release contains geophysical and water-quality property data measured by the U.S. Geological Survey (USGS) along downstream continuous profiles in surveyed reaches of Elm Brook, Hartwell Brook, and the Shawsheen River near Hanscom Air Force Base in Bedford, Massachusetts. The geophysical data consist of spatial profiles of waterborne self-potential (WaSP) voltages attributed to...

Wells drilled during oil and gas exploration use drilling fluids to cool and lubricate the drilling bit and clear the borehole of cuttings. These fluids are recycled during the drilling process, but eventually can no longer be used. This is an important waste stream from petroleum generation that requires disposal. Chemical characterization of these materials is important to determine if...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Boone and Roubidoux aquifers in northeastern Oklahoma by using MODFLOW-NWT (version 1.1.4) with the Newton formulation solver to simulate groundwater flow and account for the drying and rewetting of cells within the...

Open pit uranium mining in Atascosa, Karnes, and Live Oak Counties in the Texas gulf coast region was active during the second half of the 20th century. Understanding the history of these mining operations is important for proper management and restoration. Although some mines have extensive records documenting the locations and extents of mining pits and mine waste-rock piles, and...

The karstic Edwards and Trinity aquifers are classified as major sources of water in south-central Texas by the Texas Water Development Board, and both are classified as major aquifers by the State of Texas. The purpose of this data release is to present the data that were collected and compiled to describe the geologic framework and hydrostratigraphy within parts of Bandera and Kendall...

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated...

This dataset documents depth to groundwater measurements made from wells screened in the Chicot aquifer, Evangeline aquifer, Jasper aquifer, Burkeville confining unit, Catahoula confining unit, or a combination of these hydrogeologic units in the greater Houston area, Texas for 2023. The U.S. Geological Survey (USGS) prepared this dataset in cooperation with the Harris‐Galveston...

A previously published MODFLOW-NWT groundwater-flow model for the Rush Springs aquifer in western Oklahoma (using 1 steady state stress period followed by 444 monthly stress periods representing 1979-2015; Ellis, 2018a) was used as the basis of several groundwater-use scenarios. The model is a 3-layer model including the Cloud Chief formation (confining unit of the Rush Springs aquifer)...

This data release preserves an extensive archive of 15,475 historical (1918–2020) geophysical logs from wells across Texas, including over 10,000 collected during various studies and more than 2,000 donated records. The original hard-copy logs are housed at the U.S. Geological Survey Oklahoma-Texas Water Science Center (OTWSC) in Austin, Texas. Digitized materials are provided as zipped...

This data release documents socioeconomic and water demand indicators for the Mekong River delta region. The Mekong River provides many valuable benefits to the 60 million Southeast Asian residents living in its Basin. Maintaining adequate supplies of water in the Mekong River Basin is vital for food security. However, the Mekong River Basin is increasingly stressed by infrastructure...
