Background
and Goals
In Dickinson Bayou Tidal (Segment 1103), concentrations of
dissolved oxygen are less than optimum compared to standards
defined for the support of aquatic life.
Oxygen, which dissolves in water, is essential for the survival
of aquatic life. While the amount of dissolved oxygen in water
fluctuates naturally, various human activities can cause unusually
or chronically low dissolved-oxygen levels which may harm fish and
other aquatic organisms.
The TMDL project will evaluate the effects of low dissolved
oxygen on aquatic life and determine the actions necessary to
maintain water quality in the tidal portion of Dickinson Bayou.

Public
Participation
Project staff are informing the public about this project
through the Dickinson Bayou Watershed Partnership, and through
public meetings and notices in print and electronic media. Meetings
about the TMDL project are open to everyone.
Watershed Partnership
Stakeholders in the watershed have formed the Dickinson Bayou Watershed
Partnership
to implement activities that improve water
quality in Dickinson Bayou. Information about the Partnership’s
meetings is available on their Web site.
The TCEQ will work with this existing forum to participate with
the public in developing and implementing the TMDL. In addition to
meeting with the Dickinson Bayou Watershed Partnership, the TMDL
Program hosted two meetings to provide information about the
project to the public at large. Summaries of those meetings are
available below as PDF files. (Help with PDF.)
