Water Quality Tools

Water Quality Viewer

The San Antonio River Authority’s Water Quality Viewer displays the monitoring efforts for the Texas Commission on Environmental Quality (TCEQ) Clean Rivers Program and summarizes how the water quality in the San Antonio River Basin compares to the Texas Surface Water Quality Standards (TSWQS) using the latest TCEQ Integrated Report assessment.

Through the Texas Clean Rivers Program, the BRWM collect surface water, stormwater and sediment chemistry, physical, and biological data within the San Antonio River Basin.

Water Quality Modeling Tools

A key component to holistic watershed master planning and stormwater management is the identification and implementation of best management practices (BMPs) and low-impact development (LID) strategies to address urban runoff pollution.  Until now, the selection of BMP and LID strategies has been limited to qualitative planning, hindering the planners’ ability to discern effective BMP/ LID practices without long-term monitoring. Consequently, the San Antonio River Authority (SARA) lead the development of several innovative water quality modeling tools to allow quantitative water quality master planning and BMP/LID prioritization for three major watersheds in the San Antonio River Basin. The SARA project earned a Gold Medal in the 2016 American Council of Engineering Companies (ACEC) Texas Engineering Excellence Awards, and an ACEC National Recognition Award.
