||In Charlotte-Mecklenburg, 81% of watersheds contain streams which are considered "impaired." That means they are not clean enough for their intended use, which is recreation.
Check out these maps and automated tools to see the water quality in local streams--both at this moment and over time.
You can check water quality in real time thanks to about three dozen automated sensors located in streams around Charlotte-Mecklenburg. The sensors are linked to Storm Water Services computers.

The state of North Carolina also analyzes water quality in local streams to produce the 303d streams list
Every two years, the state lists streams that are impaired for their intended use. 303(d) refers to the section of the federal Clean Water Act that requires that the list be developed. A stream is listed as impaired for its intended use or is considered supportive for its intended use.
