Watershed Facts
- The creek is often dry upstream of Pecos
Street in West Austin; however, a nice large spring is located
just downstream of Pecos Sreett so the rest of the creek has
water most of the year.
- Taylor Slough North Creek mainly flows through
residential areas.
- Taylor Slough North Creek watershed
passes through the environmentally sensitive Northern Edwards
Aquifer Recharge Zone where water travels through caves and
sinkholes to “recharge” the aquifer.

Benthic macroinvertebrate
community is fair, diatom community is fair |
- Absence of pollution-intolerant diatom species
suggests water quality may be impacting aquatic life; silt and
sedimentation may be impacting diatom community.
- Development near creek banks resulted in
poor channel and riparian conditions.
- Elevated levels of PAH may be harmful to
aquatic life.
High nutrient levels may be result of leaking wastewater lines
and residential fertilizer application.
- Staff research indicates the source
of high PAH levels may be from parking lot sealants.
