Lavaca River Above Tidal and Rocky Creek: A Community Project to Protect Recreational Uses

A project to reduce bacteria and protect recreational safety in the Lavaca River Above Tidal and Rocky 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.

Counties: Lavaca, Jackson
Parameter: Bacteria
River Basin: Lavaca
Segment: 1602, 1602B

Background and Goals

The Lavaca River Above Tidal (Segment 1602) and Rocky Creek (Segment 1602B) are located on the Texas Gulf Coast. The watershed of the combined segments lies primarily in Lavaca and Jackson counties. The above-tidal portion of the Lavaca River is a perennial (always flowing) stream. Rocky Creek, a tributary of the Lavaca River, is also perennial, and joins the Lavaca River just below the city of Hallettsville.

High concentrations of bacteria, which are found in both human and animal waste, have been observed in both water bodies—since 2008 for the Lavaca River Above Tidal and since 2014 for Rocky Creek. The presence of these bacteria may indicate a health risk to people who swim or wade in the water bodies—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 is developing a total maximum daily load (TMDL) and an implementation plan (I-Plan) to reduce bacteria in the Lavaca River and Rocky Creek.

Get Involved

Staff from the Texas Water Resources Institute (TWRI) have been working with communities, interest groups, and local organizations to distribute information about this project and involve stakeholders in developing the I-Plan for watershed improvement. All public meetings about this project are open to anyone interested. Watch for meeting announcements here and on the TWRI website Exit the TCEQ.

Updated Information Next Meeting

November 28, 2017
6:00 p.m.
Sign-in will begin at 5:45 p.m.

Wied Hall
Lavaca County, located between Shiner and Hallettsville on Hwy 90A

At this meeting, citizens will be updated on the information collected from both RUAA field surveys that may be used to determine whether primary contact recreation is occurring and if the current water quality standard is appropriate.
