San Antonio Texas consistently ranks as one of the fastest growing large cities in the United States. Urban development can affect groundwater quality as trees and open space are replaced by buildings and roads, increasing the amount of urban runoff draining directly into the Edwards aquifer. A network of sophisticated surface water and groundwater monitoring sites is being used to help managers...

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

Suspended sediment and nutrients from greater San Antonio can affect instream ecological health of the San Antonio River and ultimately impact Gulf of Mexico bays and estuaries. Real-time monitoring in urban and rural parts of the river basin may provide a glimpse into the importance of urban sediment and nutrient sources. Real-time sensors provide a tool to better understand and manage water...

The USGS Texas Water Science Center provided Big Bend National Park with a comprehensive assessment of the status of instream and riparian-zone biological resources along with information and tools needed by Park staff to address the effects of continued low flows and water-quality degradation of the Rio Grande through Big Bend National Park.

THIS PROJECT WAS COMPLETED IN 2019.

A select number of USGS Oklahoma-Texas Water Science Center (OTWSC) gaging stations are equipped with cameras. Photos are taken at approximately 5 minute intervals. All gaging station cameras in Oklahoma and Texas are listed on this page.

The USGS Texas Water Science Center (TXWSC) 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 effects on...

The USGS Texas Water Science Center assesssed salinity of the Pecos River Basin from Santa Rosa Lake, New Mexico to the confluence of Pecos River and Rio Grande, Texas. This assessment included an extensive literature review, compilation of previously published salinity related data, data gap analysis, additional data collection to fill data gaps, and identification of potential areas of elevated...

Streamer is an online mapping application for exploring downstream and upstream along America’s rivers and streams. Since Streamer was first released in 2013, scientists, water managers, students, and citizens have used Streamer extensively. The mobile friendly version takes most of the features from the desktop version and packages them into an intuitive, easy-to-use format on a smartphone or...

The Texas Water Dashboard is a web mapping application that presents U.S. Geological Survey (USGS) real-time stream, lake, reservoir, precipitation, and well data in Texas in context with current weather and hazard conditions. Real-time measurements from over 750 USGS observation stations in Texas are accessible from the map viewer, along with complementary map layers such as current precipitation...

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...
