Protecting Our
Waterways Together
McGregor’s Stormwater Management Program (SWMP) is a proactive community effort to keep Harris Creek and the South Bosque River healthy for generations to come.
Harris Creek (1246A) and the South Bosque River (1246) are not listed on the 303(d) impaired waters list. This program is a forward-thinking investment to prevent future degradation—not a response to pollution already present.
Why McGregor Has a Stormwater Program
Due to growth along the US 84 corridor and near McGregor Airport, the 2020 Census connected McGregor to Waco’s urbanized area. This triggered designation as a Newly Regulated MS4 (Municipal Separate Storm Sewer System) by the Texas Commission on Environmental Quality (TCEQ).
The City submitted its Stormwater Management Program and Notice of Intent by February 11, 2025 — committing to protect water quality for McGregor’s approximately 5,321 residents over a five-year permit cycle.
The program is organized around six Minimum Control Measures (MCMs), each targeting a specific aspect of stormwater pollution prevention.
Water quality monitoring station 20393 is located at the downstream end. The majority of northern McGregor drains to this creek.
Monitoring stations 11611 and 11817 monitor this receiving water. Southern portions of McGregor drain to this river.
McGregor operates a stormwater conveyance system including roads, catch basins, gutters, ditches, channels, and storm drains throughout the city limits.
How We Protect Our Water
Each MCM represents a category of best management practices (BMPs) the City will develop, implement, and enforce over the five-year permit term.
Share educational materials on stormwater impacts and steps the public can take to reduce pollutants in runoff.
Host or support events that give residents and businesses direct opportunities to improve water quality.
Map the storm drain system, train staff, and empower residents to report illegal dumping and illicit connections.
Construction Site Runoff Control
Require erosion and sediment controls for construction activities and provide public channels for reporting concerns.
Post-Construction Management
Require structural and non-structural BMPs for new development and ensure long-term maintenance of stormwater controls.
Train City employees, inspect municipal facilities, and ensure contractors comply with stormwater best practices.
