Watershed Facts
- In response to citizen complaints, investigators
find an average of seven pollution spills each year in Dry North
Creek; the most common spill type is sewage, followed by construction
wastes.
- The highest portion of Dry North Creek watershed
drains to the environmentally sensitive Edwards Aquifer Recharge
Zone where water travels through caves and sinkholes to “recharge”
the aquifer.

- Absence of pollution-intolerant diatom species
suggests water quality may be impacting aquatic life.
- Despite heavy residential development, Dry
Creek North is a high gradient stream with significant habitat
and thick canopy cover. .
- High nitrate and conductivity may be
result of groundwater impacts from seep and spring inputs.
