Data

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

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...

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...

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)...

This data release consists of historical borehole geophysical data collected by various entities and digitally recreated by the U.S. Geological Survey to characterize the physical properties of the subsurface in the Mississippi Alluvial Plain from Louisiana to Missouri. The geophysical log data were collected by different Federal, state, and local agencies throughout the area, and were...

This data release documents water-quality data obtained as part of an assessment of compounds of emerging concern (CECs) measured in samples collected at potable water and wastewater treatment plants in Dallas and downstream from Dallas in the Trinity River from August 2009 to December 2013 by the U.S. Geological Survey in cooperation with the City of Dallas, Dallas Water Utilities...

This dataset documents the depth to groundwater measured in wells screened in the Chicot, Evangeline, and Jasper aquifers in the Houston-Galveston region, Texas for 2019. The U.S. Geological Survey prepared this dataset in cooperation with the Harris-Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria...

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

Hydrophobic (sediment-associated) pesticides were measured in sediment samples collected from 82 wadeable streams and in biofilm in 54 of those streams in the Central California Foothills and Coastal Mountains ecoregion.115 current-use and 3 legacy pesticides were measured in stream sediment; 93 of the current-use pesticides and the same 3 legacy pesticides were measured in biofilm. On...

Consumptive use (CU) of water is an important factor for determining water availability and groundwater storage. Many regional stakeholders and water-supply managers in the Upper Rio Grande Basin have indicated CU is of primary concern in their water-management strategies, yet CU data is sparse for this area. This polygon feature class, which represents irrigated acres for 2015, is a...
