Upper Guadalupe River: A Plan to Reduce Bacteria
In a portion of the Upper Guadalupe River (Segment 1806) in Kerrville, since 2002 high concentrations of bacteria have indicated a possible health risk to people who swim or wade in the water body—activities called “contact recreation” in the state’s standards for water quality.
In 2007, the commission adopted a total maximum daily load (TMDL) for the impaired reach of the river, which includes two small areas within the city of Kerrville. In 2011, the commission approved a TMDL Implementation Plan developed by stakeholders in the watershed.
The Upper Guadalupe River Authority coordinated with personnel from the City of Kerrville, Kerr County, and the Texas Department of Transportation to install structures that deter birds on bridges, manage waterfowl along the river, and develop a "Homeowners Septic System Guide." The River Authority is also collecting routine water samples to measure the impact of these measures on bacteria levels in the river.
