Surface Water Quality


Monitoring surface water quality is one of the best ways to protect streams and lakes. It helps identify problems, determ​ine whether streams and lakes are improving or declining over time, and most importantly it helps protect quality of life and public health.

Each year, a wide range of surface ​water quality monitoring data is collected from streams and lakes throughout the City of Charlotte and Mecklenburg County.

  • Almost 15,000 water samples are collected per year and over 20 different parameters are routinely screened
  • Automated samplers at 35 locations measure five parameters per hour, 24 hours a day. This equals approximately 1.5 million measurements a year
  • Fish communities are assessed at five locations
  • Macroinvertebrate communities are assessed at 34 locations
