The U.S. Environmental Protection Agency and the Texas Commission on Environmental Quality formally approved a comprehensive 10‑year watershed protection plan for Rowlett Creek on Aug. 24, according to Texas A&M AgriLife. The plan targets the persistent E. coli contamination that has kept the creek out of state water‑quality standards since 2014.

Local partners drive the effort

City officials and community groups from Plano, Frisco, Allen, Collin County, Dallas County, the North Texas Municipal Water District, Collin College and Plano ISD collaborated with Texas A&M AgriLife to develop the strategy. Their goals include reducing storm‑water pollutants, promoting responsible lawn care and pet‑waste practices, cracking down on illegal dumping, expanding education programs, supporting flood‑management measures and maintaining ongoing water‑quality monitoring.

Key actions to lower bacterial loads

The plan outlines specific actions such as:

• Implementing best‑management practices to capture runoff before it reaches the creek.
• Educating residents on proper pet‑waste disposal and lawn‑care techniques.
• Increasing enforcement against illegal dumping and littering.
• Broadening outreach and school‑based education about watershed health.
• Integrating flood‑control projects that also improve water quality.
• Continuing regular sampling and data collection to track progress.

Science behind the contamination

Sampling at five sites along Rowlett Creek revealed that the majority of E. coli originates from animal sources, with dog waste accounting for roughly 96.9% of the total bacterial load. Other contributors include feral cats, livestock, feral hogs, ducks and wastewater‑treatment facilities.

Why the plan matters

Rowlett Creek has failed to meet Texas water‑quality standards for over a decade, prompting concerns from residents, schools and businesses that rely on the creek for recreation and irrigation. By addressing the primary sources of contamination and fostering community stewardship, the plan aims to restore the creek to a level safe for swimming, fishing and ecological health.

“Acceptance of this watershed protection plan is an important step toward improving water quality in Rowlett Creek,” said Texas A&M AgriLife professor and extension specialist Fouad Jaber. The agencies will review progress regularly and adjust actions as needed to ensure the creek’s long‑term recovery.
