Dickinson Bayou: A TMDL Project for Dissolved Oxygen
 |
|
Dickinson Bayou
|
County: Galveston
Parameter: Low dissolved oxygen
Basin: San Jacinto–Brazos Coastal
Segment: 1103
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
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 is working with this existing forum to participate with the public in developing and implementing the TMDL project.
