The Trinity River Basin is a major source of water for a large part of Texas that includes the rapidly growing Dallas-Fort Worth and Houston metropolitan areas. An application of the Precipitation-Runoff Modeling System (PRMS) was used to conduct hydrologic simulations for the Trinity River Basin surface water model. Climate variables including daily precipitation, daily maximum temperature, and d

This dataset documents the depth to groundwater measured in wells screened in the Chicot aquifer, Evangeline aquifer, Jasper aquifer, Burkeville confining unit, Catahoula confining system, or a combination of multiple hydrogeologic units in the greater Houston area, Texas for 2021. The U.S. Geological Survey prepared this dataset in cooperation with the Harris?Galveston Subsidence District, City o

The U.S. Geological Survey (USGS), in cooperation with the Harris-Galveston Subsidence District and Fort Bend Subsidence District, constructed a finite-difference numerical groundwater-flow model of the northern Gulf Coast aquifer region for 1897 through 2018 using MODFLOW 6 with the Newton formulation solver to simulate groundwater flow and land-surface subsidence. Model parameter estimation and

Patrick Bayou, a section of the Houston Ship Channel near Deer Park, Texas, has accumulated permitted industrial wastewater discharges, municipal wastewater treatment plant effluent, and stormwater runoff from adjacent industrial facilities and nearby urban and residential areas. These discharges are suspected to be the primary sources of the sediment contamination in the Patrick Bayou section of

The geochemical data included here were generated as part of the Earth Mapping Resources Initiative (Earth MRI), which was developed by the U.S. Geological Survey (USGS) in response to a Federal directive calling on various Federal agencies to address potential vulnerabilities in the Nation's supply of critical mineral resources. Earth MRI is a partnership between the USGS, State Geological Survey

The datasets in this data release contain the results of an analysis of the U.S. Geological Survey's historical water-use data from 1985 to 2015. Data were assessed to determine the top category of water-use by volume. Data from groundwater, surface water, and total water (groundwater plus surface water) use were parsed by water type, and the top category of use by county or the geographic region

The Transboundary Aquifer Assessment Act was established to systematically assess priority aquifers along the U.S.-Mexico international boundary. The priority aquifers that were specified include the Hueco-Mesilla Bolsons aquifer in Texas and New Mexico and its counterpart in Mexico, the Conejos-Médanos Aquifer system, and the Santa Cruz and San Pedro aquifers in Arizona (Texas Water Development B

In 2020, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level altitude data and water-quality samples from monitoring wells at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund Site in Liberty County, Texas to evaluate the status of groundwater contamination at this previously remediated site. The dataset includes groundwater

The U.S. Geological Survey, in cooperation with the City of South Padre Island, Texas, collected base line hydrodynamic (tidal water level and current velocity) data for a near-shore area of the Laguna Madre near South Padre Island from August 18, 2021, to April 27, 2022. The data included in this data release are presented in a comma-separated values (csv) file format.

Geophysical data were collected on January 13, 2022, from a reach of East Fork Poplar Creek in Oak Ridge, Tennessee to gain a better understanding of surface water/groundwater exchanges. This data release contains the following types of data: waterborne self-potential (WaSP), and surface -water temperature and conductivity data collected by the U.S. Geological Survey (USGS) from 220-meter (m) long

The Mississippi River Valley alluvial aquifer (“alluvial aquifer”) is one of the most extensively developed aquifers in the United States. The alluvial aquifer is present at the land surface in parts of southeastern Missouri, northeastern Louisiana, western Mississippi, western Tennessee and Kentucky near the Mississippi River, and throughout eastern Arkansas. Historical (1940–2006) and recent (20

The Ogallala aquifer is contained in the Tertiary-age Ogallala Formation in the Texas Panhandle and is the primary water-bearing hydrogeologic unit of the High Plains aquifer system. The Ogallala aquifer is the primary source of water used for agricultural and municipal purposes in the Texas Panhandle. The Dockum aquifer is contained in the formations that compose the Triassic-age Dockum Group and
