Trinity River Land and Water Summit: Overview of Watersheds, Water Quality Impairments, and Planning Efforts

311 views

Published on

Given at the Trinity River Land and Water Summit in Athens, Texas, on October 2, 2013. Purpose was to highlight specific watersheds in the middle Trinity River basin and provide details on different watershed planning tools that could be used to improve water quality. Other presentations during the day explained how cattle grazing, row crop farming, and wildlife management can all accomplish water quality goals when done with the overall watershed health in mind, especially for the Trinity River that provides water for 45% of the Texas population. Presentation featured questions that the audience could answer using remote clickers for immediate feedback from the entire group. Results are on the slides and will lead to greater understanding of stakeholders in this part of the Trinity River basin. Keynote speakers were Todd Staples, Texas Agriculture Commissioner, and Bob McCan, President of the National Cattlemen's Beef Association.

Trinity River Land and Water Summit: Overview of Watersheds, Water Quality Impairments, and Planning Efforts

  1. 1. Overview of watersheds, impairments, and planning efforts
  2. 2.  WQS are the water quality criteria to protect designated uses of a water segment  Designated Uses ◦ Recreation ◦ Aquatic Life Use ◦ Public Water Supply ◦ General  Impaired ◦ Doesn’t meet criteria for designated uses according to water quality standards by TCEQ ◦ Placed on 303(d) list and action must be taken within 13 years from listing (TMDL, WPP)
  3. 3.  Regulatory  Focuses only on pollutant(s) causing impairment  Water body always on 303(d) list  Voluntary, community- driven  Holistic – focuses on all potential pollutant sources in watershed  Water body usually (not always) on 303(d) list Watershed Protection Strategies

  13. 13.  Method to set standards appropriate for each waterbody  Structured scientific assessment of the factors affecting the attainment of uses which may include physical, chemical, biological and economic factors  May result in change in water quality standards for that waterbody  Involves more intensive water quality sampling and habitat assessment
  14. 14.  Potential reasons for lowering a use or criteria: ◦ Naturally-occurring substances ◦ Natural flow conditions ◦ Human-caused conditions that cannot be remedied ◦ Hydrologic modifications (dams, intakes, etc.) ◦ Physical conditions of the water body ◦ Substantial economic and social impacts
  15. 15.  “Contact Recreation” use category  High levels can cause sickness if ingested  Measured in colonies/100 mL  Sources: ◦ Wastewater effluent ◦ Failing septic systems ◦ Feral hogs ◦ Livestock ◦ Wildlife ◦ Natural in the system
