Water Quality: Rivers, Lakes, and Estuaries

Developing Surface Water Quality Standards

• Surface Water Quality Standards
  Establishes explicit goals for the water quality of streams, rivers, lakes, and estuaries throughout the state.
• Procedures for Implementing Water Quality Standards in Permitting
  Explains how water quality standards are applied to permitted wastewater dischargers.

Monitoring and Assessing Surface Water Quality

• Surface Water Quality Monitoring
  Coordinating the collection of physical, chemical, and biological samples from more than 1,800 sites and continuous-monitoring stations in selected watersheds throughout the state.
• Clean Rivers Program
  Regional water authorities working with the TCEQ for clean water and science-based decisions.
• Texas Integrated Report of Surface Water Quality
  Describes the status of Texas’ natural waters based on historical data.

Protecting and Restoring Surface Water Quality

• Watershed Action Planning
  Coordinating, documenting, and tracking the actions necessary to protect and improve the quality of the state’s streams, lakes, and estuaries.
• Targeting Limits: Total Maximum Daily Load (TMDL) Program
  Improving impaired surface waters by reducing pollution.
• Pollution from Runoff: Nonpoint Source Program
  Implementing activities that prevent or abate pollution caused by the runoff of small amounts of pollutants from a large number of sources.
• Galveston Bay Estuary Program
  Balancing economic and human needs with available natural resources in the Galveston Bay watershed.
• Coastal Bend Bays and Estuaries Program
  Improving the health of the bay system through a voluntary partnership with industry, bay users, local governments, and others.
• Clean Water Certification for Boat Sewage
  Texas has requirements for marine sanitation devices and boat pump-out stations. See how to obtain or renew certification, what the rules are, and how to report suspected illegal discharges.
