The
Bull Creek Study is designed to monitor the impacts on water quality
and aquatic life from urbanization activities in the watershed.
The quality of water in Bull Creek is of special interest because
it flows into Lake Austin, which is our primary drinking water
reservoir. Some of the headwater stream reaches and tributaries
of Bull Creek serve as habitat for the Jollyville salamander (Eurycea
tonkawae), a truly native and endemic Central Texas species.
