Houston-Galveston Region BIG: Implementing a Plan to Protect Recreational Uses

The goal of this project is to reduce bacteria levels in waterways of the Houston area to make them safer for recreation. The stakeholders of the Bacteria Implementation Group (BIG) and the TCEQ developed total maximum daily loads (TMDLs) for numerous river and lake segments and a regional Implementation Plan (I-Plan), which together are the road map to improving water quality. The TCEQ has adopted the TMDLs and approved the Implementation Plan.

Overview

Water quality testing found that bacteria concentrations are elevated in numerous waterways in the Houston–Galveston region. High bacteria concentrations might pose a risk to people who swim or wade in natural waters. Swimming and wading are called “contact recreation” in the state’s standards for water quality; the term refers to all recreation in which people are likely to swallow natural waters.

The goal of this project is to reduce bacteria concentrations and protect recreational safety. This project included 72 TMDLs for 60 waterway segments. Several TMDLs and segments have been added since the Implementation Plan was completed.

Watershed Counties: Brazoria, Harris, Fort Bend, Grimes, Liberty, Montgomery, San Jacinto, Walker, and Waller

Parameter: Bacteria
