State of Our Streams 2022
This page was written for Durham residents to learn about stormwater issues and to provide updates on the condition of Durham's creeks. Technical reports, such as those required under the City's NPDES permit are also available.
The State of Our Streams is an annual communications campaign to City residents about the health and cleanliness of the City's creeks and rivers. This year's State of Our Streams report is based on data collected at 23 sites across the City.
The Stormwater Quality group from Public Works takes samples monthly to assess conditions throughout the year. The Stormwater Quality group also performs investigations to find and fix pollution when evidence of water pollution is reported. This report is based on data collected throughout 2022.
Water Quality Index
Durham Stormwater uses an index specific to our city in order to express overall water quality at a specific location using a grading system. In watersheds where staff is able to take a wide variety of tests, the watershed is also given a grade through this Water Quality Index.
The Water Quality Index grade can change based on weather patterns like rainfall and temperature, as well as pollution. Each watershed in this report has a list of top sources of pollution that our team found based on investigations and stormwater hotline (919-560-7946) tips.
When we consider the health of a stream we look at four things:
- Bacteria: too much fecal bacteria in a stream can indicate sanitary sewer spills, private sewer spills, leaking/failing septic systems, or possibly an abundance of abandoned dog waste.
- Turbidity: too many small particles of sediment floating in a stream affect the plants and animals in the stream. Sediment transport and buildup can also change the way water moves in a stream.
- Nutrients: nutrient overload (too much Nitrogen and Phosphorous) causes algal blooms and can happen when leaves, yard waste, and fertilizer enter our streams through storm drains.
- Aquatic Life: the kinds of animals that live in a stream demonstrate how healthy the stream is overall. By looking at the aquatic life in a body of water, we get a sense of its overall health.
