Legend for Water Quality Assessment, Planning, and Implementation Activities by Watershed

TSSWCB Priority: In general, this represents the degree to which the TSSWCB SRM group believes agricultural and/or silvicultural nonpoint source pollution may be contributing to the water quality impairment or concern. With respect to TMDL projects, High Priority indicates projects which TSSWCB staff intend to propose to the State Board for formal concurrance, in accordance with the Memorandum of Agreement between TSSWCB and the Texas Commission on Environmental Quality (TCEQ) Regarding TMDLs, I-Plans, and WPPs. Low Priority indicates projects in which TSSWCB is involved, but for which formal concurrance will not be sought.

Waterbody Segment IDs: This represents the identification number assigned to each waterbody by the TCEQ; some listings include multiple segment numbers.

TWQI Categories: This represents the overall condition of the waterbody as determined by the TCEQ and published in the Texas Water Quality Inventory.

  • Category 1 - All standards are attained; no evidence that nonattainment of any standard will occur in the near future.
  • Category 2 - Some standards are attained; no evidence that nonattainment of any standard will occur in the near future; and insufficient or no data and information are available to determine if the remaining standards are attained.
  • Category 3 - Insufficient or no data and information to determine if any standard is attained.
  • Category 4 - Standard is not attained or nonattainment is predicted in the near future due to one or more parameters, but no TMDLs are required.
  • Category 5 - Standard is not attained or nonattainment is threatened in the near future for one or more parameters. Category 5 is the 303(d) List.
    • Category 5a - TMDLs are underway, scheduled, or will be scheduled for one or more parameters.
    • Category 5b - A review of the standards for one or more parameters will be conducted before TMDLs are scheduled.
    • Category 5c - Additional data or information will be collected for one or more parameters before TMDLs are scheduled.

Impairments/Concerns: This represents the individual water quality parameter(s) that is (are) not attaining water quality standards or in danger of not attaining standards for a given designated use.

Activities: This indicates the specific improvement mechanism that is being utilized by the State of Texas to remedy a water quality concern or impairment; lead agency indicated. TMDL = Total Maximum Daily Load. I-Plan = Implementation Plan. WPP = Watershed Protection Plan.
