The U.S. Environmental Protection Agency and Texas Commission on
Environmental Quality have approved the Lake Granbury Watershed
Protection Plan (WPP), which was created to address concerns about
levels of E. coli found in some of the man-made coves at the Lake Granbury.
Over the last several decades, Hood County has experienced rapid growth.
A considerable portion of the development around the lake is located on
man-made canals and coves. These coves are shallow, dead-end bodies of
water with little mixing or interaction with the main body of the reservoir.
A substantial portion of the developed area around Lake Granbury consists
of unincorporated subdivisions that do not have sewage collection systems or
centralized sewage treatment facilities. These areas rely on individual on-site
septic systems for household waste management. Approximately 9,000 septic systems
are located in the immediate vicinity of Lake Granbury.
For the last several years, regular water quality testing on Lake Granbury
coves and canals has found elevated concentrations of E. coli bacteria in
some areas. These elevated bacteria levels could pose a danger for contact
recreational use such as swimming or water skiing. E. coli is a bacteria normally
found in the intestines of humans and other warm-blooded animals.
The Lake Granbury Watershed Protection Plan Project development was funded by
federal (319) Non-Point Source grant dollars provided to the Texas Commission on
Environmental Quality (TCEQ) by the United States Environmental Protection Agency (EPA).
The TCEQ partnered with the Brazos River Authority to develop a Watershed Protection
Plan (WPP). The WPP provides an assessment of the existing and potential water quality
threats from elevated bacteria concentrations within the Lake Granbury watershed and develops
a strategy to improve and protect water quality within Lake Granbury. Information obtained from this project will provide federal, state and local decision-makers with a variety of mechanisms that can be employed to promote the orderly restoration of the lakes aquatic environment and to prevent additional degradation.
Stakeholder Advisory Group
A Stakeholder Advisory Group was created to establish project communication among local
stakeholders. Specific tasks that are undertaken by the stakeholders group include: identification
of areas with the greatest concerns; making recommendations for additional monitoring;
and making recommendations on management measures to improve water quality. Stakeholder
meetings were held on a recurring basis to enhance and support participation of stakeholders
(including the general public and other interested parties), enhance public understanding of
the project, and encourage early and continued participation in selecting, designing, and
implementing management measures.
