Data

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 w

Using the National Oceanic Atmospheric Administration’s (NOAA) Air Stagnation Index (ASI), the total number of days during 2007–2016 with atmospheric conditions conducive for stagnant air conditions in the conterminous U.S. are documented in raster format geospatial data. These data provide the number of days that would allow the temporal buildup of atmospheric pollution (NOAA, 2017). NOAA provide

Beaches and water recreation are important to the South Padre Island, Texas area and across the United States. The movement of sediment in channels along beaches and the nearshore environment is important for coastal stakeholders and resource managers. Sediment removed by maintenance dredging is often placed back into the littoral system for potential beach replenishment. The movement of sediment

In cooperation with the Texas Commission on Environmental Quality (TCEQ), the U.S. Geological Survey (USGS) utilized various field and laboratory methods to determine the presence and concentration of cyanobacteria, cyanotoxins, and taste-and-odor compounds in Texas water bodies. This data release documents the results from water-quality samples collected from 41 water bodies in Texas during 2016-

Declining groundwater levels in the Hueco Bolson have raised concerns about the amount of available groundwater and the potential for water-quality changes. Fresh groundwater stored in the aquifer is bordered by regions of brackish-to-saline groundwater, and as the water levels in the Hueco Bolson have declined the local and regional hydraulic gradients have been altered such that the brackish-to-

The Ozark Plateau aquifer system stretches across approximately 70,000 square miles (mi2) of Arkansas, Missouri, Kansas and Oklahoma, and is composed of many hydrogeologic units, such as the Boone aquifer and the Roubidoux aquifer. However, this data release is focused on only 11,000 mi2 in northern Arkansas, southeastern Kansas, southwestern Missouri, and northeastern Oklahoma. The Boone aquifer

As much as 22 inches of rain fell in Oklahoma in May 2019, resulting in historic flooding along the Arkansas River and its tributaries in eastern and northeastern Oklahoma. The flooding along the Arkansas River and its tributaries began in May continued into June 2019. Peaks of record were measured at nine U.S. Geological Survey (USGS) and U.S. Army Corps of Engineers (USACE) streamgages on variou

The U.S. Geological Survey (USGS) undertook a 5-year study beginning in 2016 to assess groundwater availability for the aquifers proximal to the Gulf of Mexico from the Texas-Mexico border to the western part of the panhandle of Florida; these aquifers are collectively referred to as the coastal lowlands aquifer system. This study is one of several regional groundwater availability studies being d

This dataset provides compiled and computed data from 1900 through 2017 associated with streamflow statistics used to perform regional analyses for the Brazos, Colorado, Big Cypress, Guadalupe, Neches, Sulphur, and Trinity River Basins. These seven river basins are mostly within Texas, but parts of some of the basins extend into New Mexico and Louisiana. Because changes in precipitation, temperatu

The U.S. Geological Survey, in cooperation with the Harris?Galveston Subsidence District, City of Houston, and the Fort Bend Subsidence District, produced a dataset through 2018 of compaction values in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas. This dataset contains compaction values of subsurface sediments (mostly in the fine-grained silt and clay layers because li

The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water for r

The U.S. Geological Survey and Desert Research Institute, in cooperation with the Natural Resources Conservation Service, Texas State Soil and Water Conservation Board, Victoria County Groundwater Conservation District, Victoria Soil and Water Conservation District, and the San Antonio River Authority, evaluated the hydrologic effects of Vachellia farnesiana var. farnesiana (huisache) removal on r
