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.

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.

Announcing Streamer - Developed and Powered by the USGS Texas Water Science Center
On July 17, 2013, the Texas Water Science Center and National Atlas of the United States announced the launch of Streamer - a new National Atlas Dynamic Map that allows anyone to trace up and down America's major streams and to learn a little about the surface waters, people, and places along each trace. Streamer lets you navigate rivers in the United States the way other interactive maps help you drive your vehicle from one place to another. Unlike our nation’s road network, which provides many choices for traveling between two locations, America’s surface waters are somewhat like a network of one-way streets. You can certainly navigate upstream, but all water flows one way: downhill. Use Streamer to trace downstream along that downhill path or use Streamer to trace upstream to highlight rivers at higher elevations that flow to your starting point.
In the first 5 days since the release of Streamer, the USGS Texas Water Science Center has seen more than 35,000 visits to the Dynamic Map, 120,000 stream traces performed, with over 1 billion river miles traced and counting....
Streamer is directly accessible from the National Atlas homepage. The National Atlas homepage now includes an animation that gives you an overview of the application and its exciting new capabilities!
