Lake Houston: A TMDL Project for Bacteria
Background—Meetings—Additional Information—Contact
Background
The Texas Commission on Environmental Quality has determined that Lake Houston and several tributaries sometimes have bacteria levels that are higher than state standards for contact recreation. The State of Texas requires that water quality in the Lake Houston watershed be suitable for swimming,wading, fishing, and aquatic life.
Swimming and wading is called contact recreation in the State's standards for water quality, referring to all recreation in which people come in direct contact with the water. People who swim or wade in the bayous may be at risk because of high level of bacteria. Bacteria from human and animal waste often indicate the presence of disease-causing microorganisms, which pose a threat to public health.
In response to the elevated bacteria levels in the bayous, the TCEQ initiated a total maximum daily load (TMDL) project to determine the measures necessary to support recreational uses in these water bodies. The goal of a TMDL is to determine the amount (or load) of a pollutant that a body of water can receive and still support its designated uses. The load is then allocated among all the potential sources of pollution within the watershed, and measures to reduce pollutant loads are developed as necessary.
The Lake Houston TMDL project is still collecting and analyzing data. More details are included in past meeting information, below, or on TCEQ’s project website: www.tceq.state.tx.us/implementation/water/tmdl/82-lakehouston.html.
Meetings
The next series of open houses to provide an opportunity for stakeholders to learn about and provide input regarding data collection and analysis will be in 2010. If you are interested in a presentation or newsletter article for your community or organization, please contact:

In the meantime, stakeholders from Lake Houston and other watersheds in the region are working to begin developing an implementation plan to reduce bacteria in the waterways. The Bacteria Implementation Group (BIG) is the committee responsible for developing the plan. Please visit the BIG webpage for more information and to learn how to be involved. An informational open house will be hosted at H-GAC on Tuesday, December 8, 2009, from 1:00 pm to 4:00 pm. More information can be found here.
