Seven-year study Guides City
Occasional blooms of oxygen-depleting algae indicate vulnerability of our water resources to nearby development
City of Austin, Environmental Resources Management Division
April 1997
The first long-term study of Barton Creek reveals a still pristine system in many respects, but one that is at risk. Recommendations for preservation include easement and wildlife area expansion and the improvement of flood and water quality control structures.
The general understanding of the Barton Creek system informed our work as we faced new threats to the system, and identified pavement sealants as the source of PAH contamination in Barton Creek and Barton Springs.
