Oklahoma-Texas Water Science Center
Water information is fundamental to national and local economic well-being, protection of life and property, and effective management of water resources. USGS works with partners in Oklahoma and Texas to monitor, assess, conduct targeted research, and deliver information on a wide range of water resources including streamflow, groundwater, water quality, and water use and availability.

Hydrogeologic investigation, framework, and conceptual flow model of the Antlers aquifer, southeastern Oklahoma, 1980–2022
The 1973 Oklahoma Groundwater Law (Oklahoma Statute §82–1020.5) requires that the Oklahoma Water Resources Board conduct hydrologic investigations of the State’s groundwater basins to support a determination of the maximum annual yield for each groundwater basin. Every 20 years, the Oklahoma Water Resources Board is required to update the hydrologic investigation on which the maximum...
Comparison of hydrologic data and water budgets between 2003–08 and 2018–23 for the eastern part of the Arbuckle-Simpson aquifer, south-central Oklahoma
The Arbuckle-Simpson aquifer is divided spatially into three parts (eastern, central, and western). The largest groundwater withdrawals are from the eastern part of the Arbuckle-Simpson aquifer, which provides water to approximately 39,000 people in Ada and Sulphur, Oklahoma, and surrounding areas. The Arbuckle-Simpson aquifer, including the eastern part, is designated a sole source...
Water-budget analysis of the Medina and Diversion Lake system, with estimated recharge to the Edwards aquifer and the upper zone of the Trinity aquifer, Bandera, Bexar, and Medina Counties, Texas, 1955–2022
The U.S. Geological Survey—in cooperation with the San Antonio Water System and the Edwards Aquifer Authority—used data collected during four different periods (March 1955–August 1964, October 1995–September 1996, March 2001–June 2002, and March 2017–October 2022) as part of a new study to refine previously derived relations between the altitude of the water surface of Medina Lake and...

Preliminary Research Sheds Light on Proper Analysis and Sample Handling for the Tire-Derived Contaminants 6PPD and 6PPD-quinone
Tire and road wear particles have been shown to cause acute effects to sensitive aquatic animals and degrade their habitats. U.S. Geological Survey (USGS) scientists developed methods to accurately identify aquatic compounds, such as 6PPD and 6PPD-quinone, that can cause acute mortality events in coho salmon (Oncorhynchus kisutch).

Socio-Hydrology
The Socio-Hydrology Team conducts interdisciplinary studies spanning socioeconomic, hydrologic and climate science. Applying qualitative and quantitative approaches, we help stakeholders identify and assess a suite of water and climate risks. Our methodology provides a means for resource managers, practitioners, and communities to analyze and evaluate risks, vulnerability, and resiliency to...
Microplastics in Tributaries to Galveston Bay
Galveston Bay is the habitat of many organisms including many species of oysters, fish, and birds. USGS scientists from the Oklahoma-Texas Water Science Center are conducting a study, in cooperation with the Galveston Bay Estuary Program, to assess the occurrence and abundance of microplastics (plastic particles smaller than 5 mm in diameter) in Galveston Bay and its tributaries.
