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. The amount of dissolved oxygen in water fluctuates naturally, and low dissolved oxygen is a common natural occurrence in some coastal waters like Dickinson Bayou. Various human activities can also cause unusually or chronically low dissolved-oxygen levels, which may harm fish and other aquatic organisms.

This project will evaluate the effects of low dissolved oxygen on aquatic life and determine the best strategy for managing water quality in the tidal portion of Dickinson Bayou.

Public Participation

Stakeholders in the watershed formed the Dickinson Bayou Watershed Partnership Exit the TCEQ to implement activities that improve water quality in Dickinson Bayou. Information about the Partnership’s meetings Exit the TCEQ 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.

TCEQ-Hosted Public Meetings

In addition to meeting with the Dickinson Bayou Watershed Partnership, the TMDL Program has hosted meetings to provide information about the project to the public at large.

Reports

The TCEQ proposed draft TMDLs in 2008. Based on comments received, the proposed TMDLs were not adopted.
