Project Background
Clear Creek Above Tidal is a suburban freshwater stream located
in the southernmost portion of the city of Houston, Texas. Water
quality testing has found that concentrations of chlorides and
total dissolved solids in Clear Creek Above Tidal (Segment 1102)
are not optimum for supporting aquatic life.
The goal of this project is to reduce chloride and TDS in Clear
Creek to levels that support a healthy aquatic community.

TMDLs for Clear Creek Above Tidal
The goal of a TMDL is to restore the full use of a water body
that has limited quality in relation to one or more of its uses.
The TMDL defines an environmental target by determining the extent
to which a certain pollutant must be reduced in order to attain and
maintain the affected use. Based on this environmental target, the
state develops an implementation plan to mitigate anthroprogenic
sources of pollution within the watershed and restore full use of
the water body.
An earlier version of these TMDLs was approved by the Commission
on August 10, 2005 and submitted to the EPA for final review and
approval. The TMDLs were revised in response to comments received
from the EPA. The revised document includes a new section
describing reasonable assurance associated with implementation of
the TMDLs and corrections of mathematical errors related to the
TMDL equation.
The revised TMDLs were adopted by the commission on April 12,
2006. These TMDLs will become part of the state's Water Quality
Management Plan if approved by the United States Environmental
Protection Agency (EPA).
