Lavaca River: Coordinating Implementation

A completed project to support a wide range of implementation measures for the Lavaca River Watershed Protection Plan (WPP); primarily outreach, education, and water quality monitoring.


The Lavaca River watershed contains many segments that do not meet water quality standards for bacteria or dissolved oxygen. The Texas Water Resources Institute (TWRI) worked with local stakeholders to develop a Watershed Protection Plan (WPP) Total Maximum Daily Loads (TMDLs) and a TMDL Implementation Plan for two segments in the Lavaca River watershed in 2019 to address the elevated levels of bacteria.

The Texas Water Resources Institute:

  • Collected monthly water samples from four established monitoring locations.
  • Analyzed this new data and existing water quality data, to estimate how much pollution each major source is adding to the river.
  • Provided public education programs and convene meetings in the watershed to discuss findings.
