Strategy

The Guadalupe River Implementation Plan documents measures stakeholders are using to reduce bacteria loads. The City of Kerrville, Kerr County, and the Texas Department of Transportation have committed to partner with UGRA to implement these measures.  Their strategy includes the following actions:

  • Modify the Highway 16 bridge to reduce wildlife nesting.
  • Reduce feeding of birds and manage the waterfowl population at Louise Hays and Kerrville-Schreiner parks.
  • Educate park users and install stations for proper disposal of pet waste.
  • Repair, replace, and inspect sewage lines and septic systems.

Management measures were selected based on feasibility, costs, support, and timing.

Status

Assessment in 2014 indicates that the impaired portions of Segment 1806 are fully supporting the contact recreation use. However, the tributaries Quinlan Creek (Segment 1806D) and Town Creek (Segment 1806E) were added for nonsupport of contact recreation in 2014. Since the adopted TMDL was for the entire watershed, the TMDLs for these two tributaries will be added through an addendum in the state's Water Quality Management Plan.

Status Reports

Tracking of implementation allows stakeholders to evaluate actions taken, identify actions that may not be working, and make changes as necessary.

Stakeholders are in the fifth year of implementing their plan.

Activities

As of March 2015, the Upper Guadalupe River Authority's Bacteria Reduction Plan had funded the installation of twenty-two pet waste stations in the community. In 2014, the Flat Rock Park pet waste stations collected over 1,900 pounds of waste, which prevented this waste from washing into the river.

Education and Outreach

Educational Kiosk

This interactive kiosk, featuring the water education program Water Down the Drain, was installed in January 2013 at the Riverside Nature Center. The program guides users through several activities that teach how pollution can be washed into waterways, the effects of nonpoint source pollution, and what can be done to prevent it. This kiosk will be rotated among other public venues in the community.

Grant Funded Project to Support the I-Plan

The TCEQ's Nonpoint Source Program supported a project that implemented some aspects of the I-Plan. Its Upper Guadalupe project implemented controls of waterfowl and bird nesting under river bridges, as well as education about management of on-site septic systems.
