Current and Completed Projects of the TMDL Program

All TMDL program projects, listed in alphabetical order by project name
Title Description
Aquilla Reservoir: Improving the Quality of Drinking Water Sources A successful TMDL project to reduce atrazine in Aquilla Reservoir, which is a source of drinking water for several communities. The TMDLs are adopted and the I-Plan is complete.
Armand Bayou: Evaluating Water Quality for Aquatic Life A completed project to assess dissolved oxygen and support of aquatic life in Armand Bayou.
Arroyo Colorado: A TMDL Project for Legacy Pollutants and Organics A completed project to reduce legacy pollution from chemicals and make it safe to eat fish from the waterways. The TMDLs are adopted and the I-Plan is approved.
Arroyo Colorado: A Watershed Protection Plan A completed plan and assessment project to improve water quality in the Arroyo Colorado
Arroyo Colorado: Surveying Recreational Uses A completed project to evaluate recreational uses of the Arroyo Colorado
Assessing Toxicity in Ambient Water and Sediment in Seven Texas Water Bodies A completed project to assess the extent and severity of toxicity in ambient water and sediment in seven Texas water bodies.
Atascosa River: Evaluating the Aquatic Life and Recreational Uses A completed assessment project to evaluate concentrations of dissolved oxygen and bacteria in the Atascosa River in South Central Texas
Austin Area Watersheds: A TMDL Project to Protect Recreational Uses A community project to reduce bacteria and protect recreational safety in Waller, Walnut, and Shoal creeks and Taylor Slough in the city of Austin. The Austin community has developed an Implementation Plan (I-Plan), which together with TMDLs developed by the TCEQ with community feedback, provide the the road map for improving water quality. The commission has adopted the TMDLs and approved the Implementation Plan.
Brandy Branch Reservoir: Assessing the Safety of Fish Consumption A completed project of the TMDL Program to assess the extent of contamination in fish from Brandy Branch Reservoir
Brazos–Colorado Coastal Basin Watersheds: Protecting Recreational Uses The goal of this current project is to make recreation safer by reducing bacteria levels in waterways of the Brazos–Colorado Coastal Basin.
Carancahua Bay: A Community Project to Protect Recreational Uses A project to reduce bacteria and protect recreational safety in Carancahua Bay. The stakeholders and the TCEQ are developing a total maximum daily load (TMDL) and implementation plan (I-Plan), which together will be the road map for improving water quality.
Carters Creek Watershed: Implementing TMDLs to Protect Recreational Uses A community project to develop and implement TMDLs to reduce bacteria levels and protect recreational uses of the creek. Together, the adopted TMDL and the approved implementation plan are the road map to improving water quality in the creek.
Clear Creek Above Tidal: A TMDL Project for Total Dissolved Solids and Chloride A completed project to develop and implement total maximum daily loads for total dissolved solids and chloride in the freshwater portion of Clear Creek that is above tidal influence. The TCEQ withdrew these TMDLs via the July 2014 update to the Water Quality Management Plan.
Clear Creek: A TMDL Project for Volatile Organic Compounds A successful project to reduce pollution from volatile organic compounds (VOCs) that were making it unsafe to eat fish caught in the creek.
Clear Creek: A TMDL Project for Chlordane A completed project to address reduce chlordane in fish and protect the safety of consumers. The total maximum daily loads are adopted and the implementation plan is approved.
Clear Fork Trinity River: Evaluating Water Quality for Aquatic Life A completed project to evaluate the attainability of the presumed aquatic life use for the Clear Fork of the Trinity River
Colorado River Below E.V. Spence Reservoir: Implementing a Plan to Improve Water Quality A community project to implement TMDLs that reduce salinity from chloride, sulfate, and dissolved solids in the Colorado River below E.V. Spence Reservoir. The adopted TMDL and the approved I-Plan combined are the road map to improving water quality in the creek.
Corpus Christi Beaches: A Community Project to Protect Recreational Uses A community project to reduce bacteria and protect recreational safety at beaches along Corpus Christi Bay. The stakeholders and TCEQ are developing total maximum daily loads (TMDLs) and implementation plans (I-Plans), which together will provide the road map for improving water quality.
Dallas and Tarrant Counties: A TMDL Project for Legacy Pollutants A total maximum daily load (TMDL) project to reduce legacy pollutant loads in streams and rivers in Dallas and Tarrant Counties. Together, the adopted TMDL and the approved I-Plan are the road map to improving water quality.
Dickinson Bayou: Implementing a Plan to Protect Recreational Uses A community project to protect recreational uses through a TMDL to reduce bacteria. The TMDL is adopted and the I-Plan is approved. Together, the TMDL and I-Plan are the road map to improved water quality.
Dickinson Bayou: Investigating Low Dissolved Oxygen Conditions A completed project to assess conditions for support of fish and other aquatic life
E.V. Spence Reservoir: Implementing TMDLs for Total Dissolved Solids and Sulfate A project to improve water quality by reducing total dissolved solids (TDS) and sulfate in E.V. Spence Reservoir. Together, the adopted TMDLs and the approved I-Plan are the road map to improved water quality.
Elm and Sandies Creeks: Evaluating Aquatic Life and Recreational Uses A completed project to evaluate high bacteria and low dissolved oxygen concentrations in Elm and Sandies creeks in south central Texas
Fort Worth Area: A TMDL Project for Legacy Pollution A completed project to reduce legacy pollutants. Together, the adopted TMDL and the approved I-Plan are the road map to improving water quality.
Galveston Bay and Houston Ship Channel: Assessing Contamination from PCBs A completed project to assess sources of contamination in fish from polychlorinated biphenyls (PCBs) and evaluate options for reducing them so it is safer to eat fish from the area waterways.
Galveston Bay and Houston Ship Channel: Assessing Contamination from Dioxin A completed project to assess sources of contamination in fish from dioxin and evaluate options for reducing them so it is safer to eat fish from the area waterways.
Galveston Bay System: A Survey of Dioxin and PCBs A completed project to assess the distribution of dioxin and PCBs in the system and evaluate options for reducing them so it is safer to eat fish from the area waterways.
Gilleland Creek: Implementing a Plan to Protect Recreational Uses The goal of this current project is to keep recreation safe in Gilleland Creek by reducing bacteria levels. The adopted TMDL and the approved I-Plan combined are the road map to improving water quality in the creek.
Grace Creek: Assessing Water Quality A completed project to monitor bacteria concentrations in portions of Grace Creek and the Sabine River in Longview.
Greater Trinity Region: Implementing a Plan to Protect Recreational Uses The goal of this project is reduce bacteria levels and protect recreational safety in waterways of the Dallas-Fort Worth Metroplex. The stakeholders and the TCEQ developed total maximum daily loads (TMDLs) and an implementation plan, which together are the road map to improving water quality. The TCEQ has adopted the TMDLs and approved the Implementation Plan.
