Watershed Facts
- Cottonmouth Creek flows into Onion Creek
near Burleson Road.
- The Longhorn Pipeline runs through the Cottonmouth
Creek watershed.
- Cottonmouth has very little perpetual flow
of water, possibly due to clay-like soils and heavy agricultural
land use in this watershed.

Bad |
Benthic macroinvertebrate
community is fair, diatom community is poor |
- Absence of pollution-intolerant diatom species
suggests water quality may be impacting aquatic life; silt and
sedimentation may be impacting diatom community.
- Agricultural impacts in combination
with native soil types contribute to aquatic habitat limitation.
