The Medina River in central Texas, is a spring fed river flowing through the Edwards Aquifer recharge zone, eventually flowing into the San Antonio River. The watershed is predominantly rural but urbanizing rapidly due to expansion in the San Antonio Metropolitan area. It is one of many waterbodies in central Texas on the Texas Water Quality Inventory and 303(d) list due to high levels of E. coli. Water quality data collected demonstrates that E. coli concentrations are often higher than allowed by state standards.
In 2021 efforts began to better understand the sources of E. coli in the watershed and develop a strategy to reduce their impacts on instream water quality. The Medina River Watershed Protection Plan was subsequently funded to work with watershed stakeholders, supported by agency and university personnel to address issues and develop solutions to them in the watershed.
