Additional Studies

The National Oceanic and Atmospheric Administration (NOAA) and USGS will jointly lead the development of foundational components for region-wide monitoring.

The Oklahoma-Texas Water Science Center (OTWSC) recognizes the mutual benefits resulting from interaction with international scientific partners. Much can be learned about fundamental principles of science and applications of science and technology by looking at global perspectives. OXWSC international collaboration includes coordinated training workshops and short- and long-term assignments both...

The USGS National Water-Quality Assessment (NAWQA) Project was established by Congress in 1992 to answer the following question: What is the status of the Nation’s water quality and is it getting better or worse? Since 1992, NAWQA has been a primary source of nationally consistent data and information on the quality of the Nation’s streams and groundwater. Data and information obtained from...

The USGS Oklahoma-Texas Water Science Center (OTWSC) developed a groundwater-flow model to estimate the potential for streamflow depletion in the Lower San Antonio River based on changes in groundwater pumping in the watershed. Results from the project can be used by the San Antonio River Authority (SARA) to better understand aquifer interactions with the river and potential groundwater pumping...

The Texas Geology Web Map Viewer is the third generation in a series of Texas geologic mapping products intended to empower and expose this data to a broad range of diverse users interested in exploring the geology of the State of Texas.

The Geolog Locator allows users to search more than 7,000 digital borehole geophysical logs at over 1,700 locations. Users like hydrogeologists, groundwater hydrologists, and geologists can search and explore the online database, which primarily includes information collected by the USGS, as well some data compiled from other sources with permission.

USGS is undertaking a 3-year study of water use, availability, and change in the Upper Rio Grande Basin in one of several national “Focus Area Studies” in the Department of Interior’s WaterSMART initiative. The Upper Rio Grande study area runs 670 miles from its headwaters in Colorado through New Mexico and northern Mexico to Ft. Quitman, Texas. Along its river corridor, it is a primary source of...

USGS Oklahoma-Texas Water Science Center scientists are collecting physical and chemical water properties at selected Texas artificial reefs to provide the initial foundation to establish the status and long-term trends in the environment and information essential for sound management decisions and long-term planning.

The USGS Oklahoma-Texas Water Science Center maintains a network of continuous record gages and crest-stage gages on small watersheds in Western Texas. Data collected from these gages provides the Texas Department of Transportation with valuable watershed rainfall and runoff information to support their hydrologic research program.

Many communities along the U.S.-Mexico border have limited surface water supply and rely on transboundary aquifers for industry, agriculture, and drinking water; however, information on water needs, water quality, and the extent and functioning of these aquifers is incomplete. The Transboundary Aquifer Assessment Program (TAAP), established through a binational agreement between the United States...

The USGS Oklahoma-Texas Water Science Center (OTWSC) is completing a geophysical pilot study adjacent to Hamilton Creek in Burnet County, central Texas. The pilot study is intended to test whether electrical geophysical methods can provide information regarding the locations of dissolution cavities and preferential groundwater flow within in the Ellenburger San-Saba aquifer. Data from this study...

The USGS Oklahoma-Texas Water Science Center is monitoring sediment, surface-water, and groundwater properties at Air Force Plant 4.
