Current and Completed Projects of the TMDL Program

All TMDL program projects, listed in alphabetical order by project name
Title Description
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.
Guadalupe River Above Canyon Lake: Implementing a Plan to Protect Recreational Uses The goal of this current project is to keep recreation safe in this segment of the river by reducing bacteria levels. The adopted TMDL and the approved I-Plan combined are the road map to improving water quality in the creek.
Gulf Coastal Waters: Evaluating the Safety of Oyster Harvesting in 14 Bays A completed project to evaluate the safety of oyster harvesting in 14 bays
Houston Ship Channel: A TMDL Project for Nickel A completed project to limit nickel concentrations in the Houston Ship Channel. The TMDL is adopted and the I-Plan is approved. Together, the TMDL and I-Plan are the road map to improved water quality.
Houston-Galveston Region BIG: Implementing a Plan to Protect Recreational Uses The goal of this project is to reduce bacteria levels in waterways of the Houston area to make them safer for recreation. The stakeholders of the Bacteria Implementation Group (BIG) and the TCEQ developed total maximum daily loads (TMDLs) and their Implementation Plan, which together are the road map to improving water quality. The TCEQ has adopted the TMDLs and approved the Implementation Plan.
Jarbo Bayou: A Community Project to Protect Recreational Uses A project to reduce bacteria and protect recreational safety in Jarbo Bayou in Galveston County. The stakeholders and the TCEQ are developing total maximum daily loads (TMDLs) and an implementation plan, which together will be the road map for improving water quality.
Lake Austin - A TMDL Project for Dissolved Oxygen A completed project to improve conditions for aquatic life by increasing dissolved oxygen in Lake Austin. Together, the adopted TMDL and the approved I-Plan are the road map to improving water quality.
Lake O' the Pines: Implementing a Plan to Protect Aquatic Life A current project to improve conditions for aquatic life by increasing dissolved oxgen levels in the lake. Together, the adopted TMDLs and approved I-Plan are the road map to improved water quality.
Lake Worth Watershed: A TMDL Project for PCBs in Fish Tissue A completed project to improve water quality by reducing polychlorinated biphenyls (PCBs) in Lake Worth. The adopted TMDLs and approved implementation plan together are the road map to improving water quality.
