Water Quality


Water Quality Monitoring

The quality of water in our lakes and rivers affects the health and diversity of fish and wildlife, recreation, aesthetics and human health.   CCWMO staff monitors lakes and rivers for a variety of characteristics and pollutants to help determine the health of the water. Monitoring includes taking measurements of the following;

  • Turbidity – how much sediment is in the water
  • Bacteria
  • Total phosphorus
  • Nitrogen
  • Secchi depth – indicates the clarity of the water
  • Chlorophyll-a
  • pH
  • Dissolved oxygen – determines sustainable life
  • Temperature

Additional agencies involved in monitoring lakes and streams in Carver County include the Metropolitan Councils Watershed Monitoring Program (WOMP) and Citizen-Assisted Monitoring Program (CAMP),  Minnesota Pollution Control Agencies (MPCA) Citizen Lake Monitoring Program (CLMP), Carver County Environmental Services, Carver County Soil and Water Conservation District (SWCD), and the Minnesota Department of Agriculture (MDA). 

Water Quality Report

Each spring staff put out the annual Water Report containing information about pollutants, sources, monitoring, each watershed and more. The annual Water Quality Report is available on our Water Quality Report page.

Water Quality Map

Water Quality Map is an interactive mapping application designed for citizens to gain easy access to water quality monitoring data on lakes and rivers in the County. Within the map you can select by lake name or stream name to gather information on nutrient levels, rainfall, lake depth, secchi depth and more! 

Total Maximum Daily Loads

Lakes and Rivers that do not meet water quality standards set by MN State are listed as impaired and must complete the Total Maximum Daily Load (TMDL) process.  This process determines the sources of pollutants to the lake or river, and creates an implementation plan to improve the water quality and return the water body to its designated use. CCWMO has completed a number of TMDLs that can be found in a Projects & Reports page.
