Arenosa Creek: A Community Project to Protect Recreational Uses

A project to reduce bacteria and protect recreational safety in Arenosa Creek. The stakeholders and the TCEQ are developing a total maximum daily load (TMDL) and implementation plan (I-Plan), which together will be the road map for improving water quality.

Background and Goals

The Arenosa Creek Watershed (Segment 2453C) is located on the Texas Gulf Coast and lies primarily between the cities of Victoria and Edna. The segment comprises one AU, 2453C_01. The city of Inez is partially within the watershed.

Since 2010, high concentrations of bacteria, which are found in both human and animal waste, have been observed in the creek. The presence of these bacteria may indicate a health risk to people who swim or wade in the creek—activities referred to as “contact recreation”—in the Texas Surface Water Quality Standards.

The goal of this project is to improve water quality in order to protect recreational uses. Toward that goal, the TCEQ and stakeholders are developing a total maximum daily load (TMDL) and an implementation plan (I-Plan) to reduce bacteria in Arenosa Creek.
