Greater Trinity Region: Implementing a Plan to Protect Recreational Uses
Watershed Counties: Dallas, Tarrant
River Basin: Trinity
Segments: 0805, 0822A, 0822B, 0841, 0841B, 0841C, 0841E, 0841G, 0841H, 0841J, 0841L, 0841M, 0841R, 0841T, 0841U
Bacteria concentrations are occasionally elevated in portions of the Trinity River that flow through Dallas and Tarrant counties. High bacteria concentrations might pose a risk to people who swim or wade in natural waters. Swimming and wading are called “contact recreation” in the state’s standards for water quality; the term refers to all recreation in which people are likely to swallow natural waters.
The watersheds for the Greater Trinity River I-Plan encompass an area of 406 square miles. The human population is 1.33 million as of 2013, with a population density of approximately 3,232 people per square mile. The I-Plan implements TMDLs for:
- Upper Trinity River (Segment 0805, upper end)
- Elm Fork Trinity River tributaries of Grapevine Creek and Cottonwood Branch (Segments 0822A and 0822B)
- Lower West Fork Trinity River (Segment 0841) and 11 of its tributaries
The goal of this project is to reduce bacteria concentrations and protect recreational safety by implementing total maximum daily loads. A TMDL is like a budget for pollutants—it estimates the amount of a pollutant that a water body can receive from categories of sources and still support its designated uses.
The North Central Texas Council of Governments is working with stakeholders to implement bacteria TMDLs throughout their region.
