Current and Completed Projects of the TMDL Program

All TMDL program projects, listed in alphabetical order by project name
Title Description
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.
Lampasas and Navasota Rivers: Evaluating Water Quality for Recreational Uses A completed project of the TMDL Team to survey and assess bacteria impairments of the contact recreation use in three streams in east central Texas.
Lavaca Bay and Chocolate Bay: Evaluating Water Quality for Aquatic Life A completed project to assess support of the aquatic life use in Lavaca Bay and Chocolate Bay
Lavaca River Above Tidal and Rocky Creek: A Community Project to Protect Recreational Uses A project to reduce bacteria and protect recreational safety in the Lavaca River Above Tidal and Rocky Creek. 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.
Lower Leon Creek: A Project to Assess Bacteria A completed project to assess the extent of impairments due to bacteria in Lower Leon Creek
Lower Leon Creek: Evaluating Water Quality to Protect Aquatic Life A completed project to collect dissolved oxygen samples in the stream and add to the data available for evaluating the aquatic life use.
Lower Leon Creek: Fish Tissue Sampling Project A completed project to assess high PCB concentrations in fish tissue in Lower Leon Creek.
Lower Sabinal River: A TMDL Project for Nitrate-Nitrogen A completed project to improve water quality in the Lower Sabinal River. The TMDL is adopted and the implementation plan is approved; together, they provide the road map for improved water quality.
Lower San Antonio River: A Community TMDL Project to Protect Recreational Uses A community project to reduce bacteria concentrations and protect recreational safety in the river. The TMDLs are adopted; stakeholders are developing the implementation plan. Together, the TMDLs and I-Plan provide the road map to improving water quality.
Martin Creek Reservoir: Assessing the Safety of Fish Consumption A completed project to assess the safety of consuming fish from Martin Creek Reservoir
Matagorda Bay and Nearby Coastal Waters: A Project to Assess Dissolved Oxygen and pH A completed project to assess dissolved oxygen and pH in Matagorda Bay and nearby coastal waters
Matagorda Bay Watersheds: Protecting Recreational Uses The goal of this current project is to make recreation safer by reducing bacteria levels in waterways of the greater Matagorda Bay watershed.
Mid Cibolo Creek: A Project for Dissolved Oxygen A completed project to assess and improve dissolved oxygen concentrations in Mid Cibolo Creek in South Central Texas
Mission and Aransas Rivers, Tidal Portions: A Community Project to Protect Recreational Uses A community project to keep recreation safe in tidal segments of the Mission and Aransas rivers by reducing bacteria levels. Together, the adopted TMDLs and approved implementation plan provide the road map for improving water quality.
Navasota River: A Community Project to Protect Recreational Uses A project to reduce bacteria and protect recreational safety in the Navasota River. The stakeholders and the TCEQ are developing a total maximum daily load (TMDL), which together with its implementation plan will be the road map for improving water quality.
North Bosque River: Implementing a TMDL to Protect General Uses A project to improve water quality by developing and implementing TMDLs. The TMDLs are adopted and the I-Plan is approved; together, they provide the road map to improved water quality.
Nueces Bay: A TMDL Project for Zinc A project to develop and implement a TMDL to reduce zinc in oyster harvesting waters. The TMDL is completed and the I-Plan is approved.
Orange County Watersheds: A TMDL Project to Protect Aquatic Life and Recreational Uses A community project to improve water quality for support of recreational and aquatic life uses. TMDLs were developed and adopted for bacteria, dissolved oxygen, and pH. Stakeholders developed the approved implementation plan, which together with the TMDLs is the road map for improving water quality.
Oso Bay and the Laguna Madre: Assessing the Aquatic Life Use A completed project to assess low dissolved-oxygen conditions in Oso Bay and Laguna Madre
Oso Bay: A Community Project to Protect Recreational Uses A community project to reduce bacteria levels and protect recreational safety in the bay. Stakeholders are developing an implementation plan for the Oso Bay/Oso Creek watershed, which, together with the TMDLs, will provide the road map for improving water quality.
Oso Bay: A Project to Assess the Oyster Waters Use A completed assessment project to determine whether bacteria levels in Oso Bay are high enough to affect oyster beds in Corpus Christi Bay.
Oso Creek: A Community Project to Protect Recreational Uses A community project to protect recreational uses of the creek by reducing concentrations of bacteria in Oso Creek and in Oso Bay. The stakeholders are investigating ways to improve water quality, including development of a total maximum daily load (TMDL) and its implementation plan (I-Plan), which together are a road map for improving water quality.
