Pollution found in stormwater runoff is people pollution. Stormwater runoff carries pollution — pesticides, soil, nutrients, toxics and other residues from everyday human activities. As steward of the Highland Lakes and the lower Colorado River, LCRA actively manages stormwater runoff around the Highland Lakes.

Highland Lakes Watershed Ordinance
In response to the impact of stormwater pollution, LCRA implemented the Highland Lakes Watershed Ordinance (HLWO) to protect water quality throughout the Highland Lakes region. Development within the Ordinance area is required to protect water quality and creek erosion by providing:
- stormwater runoff volume in approved water quality management facilities (vegetated filter strips and/or water quality basins);
- Buffer zones that remain free of development;
- Installation of temporary erosion and sediment controls;
- Achievement of final stabilization to minimize sediment migration; from the site.
LCRA, through local partnerships with nurseries and gardening clubs, provides water quality education material to residents and commercial businesses. These materials strive to promote use of native and adapted plants while minimizing the need for the use of chemicals on landscape which may have a negative impact on water quality.
New quarries and mines are also covered under the HLWO and must implement measures similar to other development.
Dredge and fill activities standards are included in the Ordinance. Typical activities that fall under this portion of the Ordinance include:
- Shoreline stabilization;
- Retaining walls; and
- Removal of sediment from lakebeds
