Water Quality Assessments

Assessed through a interagency partnership with MPCA's Water Monitoring Section

Parameters assessed in each sentinel lake and available through MPCA's Environmental Data Access application:

  • Temperature and Dissolved Oxygen
  • Conductivity
  • pH
  • Phytoplankton*
  • Total Phosphorus
  • Nitrogen parameters
  • Chlorophyll a
  • Secchi depth
  • Pheophytin
  • Total Suspended Solids
  • Total Suspended Volatiles
  • Color
  • Alkalinity
  • Chloride
  • Dissolved Organic Carbon
  • Calcium
  • Magnesium
  • Sodium
  • Sulfate
  • Good Growth Habitat Volume**
  • Temperature at Dissolved Oxygen levels of 3 mg/L**

*Data not online but available at request, please contact PCA Research Scientist Steve Heiskary ([email protected]) for specific inquiries regarding sentinel lake water quality monitoring

**Indicators of thermal habitat quantity and quality derived from Temperature-Dissolved Oxygen profiles.  For more information contact DNR Habitat Research Supervisor Peter Jacobson ([email protected])
