Federal Standards
Section 303d of the federal Clean Water Act requires every state to list its surface waters that do not meet federal standards for public safety, contact recreation, fitness for use by aquatic species and other wildlife, and the presence of specific pollutants.
In 2004, Plum Creek (Seg ID 1810) was listed as a 303d surface waterway in Texas with concerns over bacteria. Currently, there are more than 400 surface water segments in Texas on the 303d List, including creeks, canals, rivers, lakes, reservoirs, bayous, and tidal segments.
Plum Creek Watershed Plan is one of 31 active watershed protection plans in Texas that have been accepted by the US EPA.

Plum Creek has high nutrient (nitrogen and phosphorus) concentrations and is impaired by high E. coli bacteria levels. According to the Texas Commission on Environmental Quality (TCEQ) Texas Water Quality Inventory and 303(d) List, Plum Creek does not meet water quality standards for aquatic life, contact recreation, and fish consumption. The TCEQ updates these data sets every two years.
Hindrances
Non-point source pollution does not come from a specific source. Instead, it originates from many places, or from a widespread area. We all contribute to non-point source pollution when we improperly use or dispose of fertilizers, pesticides, oils, grease, pet or animal wastes, and trash. In many communities, these pollutants are transported to local waterways via storm drains.
As rain flows over roads, sidewalks, and lawns, it can pick up debris, chemicals, dirt, and other pollutants in its path. This stormwater is NOT cleaned before it reaches campus creeks and lakes that connect to groundwater reservoirs. In Plum Creek and across the nation, polluted stormwater runoff is one of the greatest threats to clean water.
Non-point Sources of Pollution
- Sediments from construction, forestry operations and agricultural lands;
- Bacteria and microorganisms from failing septic systems and pet wastes;
- Nutrients (from fertilizers and yard debris) and pesticides from agricultural areas, golf courses, athletic fields and residential yards;
- Oil, grease, antifreeze, and metals washed from roads, parking lots and driveways;
- Toxic chemicals and cleaners that were not disposed of properly
- Litter thrown onto streets, sidewalks and beaches, or directly into the water by individuals.
