Volunteer monitoring reports and data

Volunteer water monitors collect valuable data used by agencies and organizations across the state to protect and manage Minnesota’s waters. Data collected by volunteers can be viewed in a variety of ways and at different scales.

  • Individual lakes and streams — Local site reports summarize data gathered at each volunteer monitoring location, compare it to other waterbodies in the local watershed, and highlight changes in clarity over time.
  • Volunteer monitoring Program annual summary — The summary maps annual water clarity averages across Minnesota, and provides information on program participation rates.
  • Transparency trends — Results describe lakes and stream sites with increasing, decreasing, or unchanging water clarity across the state.
