Urban Waters Federal Partnership - Edwards Aquifer Recharge in a Developing Landscape

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...

Urban Waters Federal Partnership - Suspended Sediment and Nutrient Delivery to the Gulf of Mexico

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...

Biological Resources of Big Thicket National Preserve, Texas

Innovations in three-dimensional seismic surveying technology spawned an unprecedented wave of oil and gas prospecting throughout Big Thicket National Preserve. The preserve resource managers were concerned about the potential impacts to aquatic resources from these operations. The USGS Texas Water Science Center (TXWSC) provided a baseline assessment of the biological resources in the...

Streamflow and Springflow at Comal and San Marcos River

The Comal and San Marcos Springs are the largest major springs in the San Antonio segment of the Edwards Aquifer in central Texas, and among the largest springs in the southwestern US. The Comal springs network in New Braunfels includes 9 main springs and hundreds of smaller springs, many located under Landa Lake. Likewise, the San Marcos springs network in San Marcos is made up of hundreds of...

Estimating Potential Effects on Streamflow from Nearby Wells in the Lower San Antonio River Basin

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...
