ABOUT THE TEXAS WSC
USGS IN YOUR STATE
USGS Water Science Centers are located in each state.
Water Resources of Texas
The U.S. Geological Survey (USGS) Texas Water Science Center works in cooperation with approximately 100 municipalities,
river authorities, groundwater districts, and State and Federal agencies in Texas to provide reliable, impartial scientific
information to resource managers, planners, and other customers. This information is gathered by the USGS Texas Water
Science Center to minimize the loss of life and property from natural disasters, to contribute to the conservation and sound
economic and physical development of the Nation's natural resources, and to enhance the quality of life by monitoring water,
biological, energy, and mineral resources.
The USGS provides real-time stream stage and stream flow, water quality, and groundwater levels for more than 650 sites in Texas.

Texas Seminar Series
10 Years of USGS Texas Water Science Seminars!
Since 2004, the USGS Texas Water Science Center has provided 100 free public seminars!
These informal Science Seminars serve to broadly share information about water issues pertinent to Texas by:
- Highlighting activities being done in the Texas Water Science Center
- Exploring scientific research results from the USGS and other agencies
- Hosting national and international subject matter experts
See upcoming seminars or browse the seminar archive at http://tx.usgs.gov/about/seminars.html.

Spotlight on Texas Projects
The Texas Water Science Center conducts hydrologic projects that address a wide variety of water-resources issues, including water supply, groundwater contamination, nutrient loading in streams, effects of land use on water quality, and basic hydrologic data collection.
All Texas Projects
Elevated concentrations of sediment-associated contaminants are typically associated with urban areas, and San Antonio is the seventh most populous city in the U.S. During 2007–09, the USGS collected streambed sediment samples during baseflow and suspended-sediment samples during stormwater runoff at 20 sites in the Medio Creek, Medina River, Elm Creek, Martinez Creek, Chupaderas Creek, Leon Creek, Salado Creek, and San Antonio River watersheds. The samples were analyzed for major and trace elements and organic compounds including halogenated compounds and polycyclic aromatic hydrocarbons (PAHs). Concentrations were mostly low compared to consensus-based sediment-quality guidelines and compared to samples collected during previous USGS studies in the Austin and Fort Worth areas. The overall degree of sediment contamination was highest in samples collected from four sites in Leon Creek and one site in the San Antonio River.

Featured Mapping Application
Streamer - Developed and Powered by the USGS Texas Water Science Center
In cooperation with the National Atlas and the National Map of the United States, the Texas Water Science Center produced Streamer, a web mapping application for tracing America’s major rivers upstream and downstream.
- search and identify tools
- USGS streamflow-gaging stations symbolized using near real-time streamflow data
- weather radar
- choice of base maps
- ability to generate a report with a map of the trace and descriptive information about the area covered by the trace
