Streams and Lakes

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...

In 2014, the Federal Emergency Management Agency (FEMA) began sponsorship of the InFRM team initiative to allow Federal teams across the States of Texas, Oklahoma, New Mexico, Louisiana and Arkansas to better align and integrate. Currently, the InFRM team is comprised of FEMA, US Army Corps of Engineers, US Geological Survey, and the National Weather Service. Information about the Interagency...

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...

A new JavaScript library, called GWIS ( G raphing W ater I nformation S ystem), can create time-series plots of information measured at U.S. Geological Survey hydrologic data collection sites across the US. Developed by the USGS Texas Water Science Center, the user-friendly interface integrates the open-source dygraphs JavaScript charting library with the hydrologic data provided by USGS water...

Real-time water-quality, streamflow and water height information for Lake Houston and the surrounding San Jacinto watershed are now available from a new web application from the U.S. Geological Survey, done in cooperation with the City of Houston.

GWWebFlow is a browser-based groundwater model viewer designed to allow users to easily explore model inputs and outputs for published and approved USGS models. It currently supports the MODFLOW family of models, including MODFLOW2005, MODFLOW-NWT, MT3DMS and SEAWAT.

The USGS Texas Water Science Center is evaluating the water-quality effects of certain herbicides used in Arundo cane eradication along the Rio Grande from Del Rio downstream to the confluence with Sycamore Creek (approximately 10 miles), along which the Texas State Soil and Water Conservation Board (TSSWCB) will be conducting cane eradication using herbicides.

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...

The effects of urbanization across the recharge zone in Bexar County and potential impact on the water quality in the Edwards aquifer is a topic of specific concern for the City of San Antonio. The USGS Texas Water Science Center is simultaneously collecting water-quality data from surface-water runoff sites and paired shallow groundwater wells within the recharge zone of the Edwards aquifer to...

The USGS Texas Water Science Center (TXWSC) 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 will give...

During 2011-2013, baseline concentrations of many different water and streambed-sediment constituents were determined at Phase I sites upstream from, within, and downstream from the area of active oil and natural-gas production within the San Antonio River Basin. With baseline conditions previously established, this study will provide current information that couples recent water and stream-bed...
