Looking for a way to help protect water quality in Minnesota? Use our map tool to find lakes or streams that need volunteer monitors. You can also see where volunteers are already monitoring.
Contact us if you have any questions on how to choose a monitoring location or to inquire on site availability.
Tips for using the map
- Click on the image to find a site to monitor.
- For optimum features, do not use Internet Explorer.
- Zoom in to make more features visible (stream names, boat access points, roads).
- Use the green banner at the top to search for addresses, measure distances, find map details, and locate the legend.
- Click on lakes, stream segments, or stream sites to view exact location descriptions and a link to enroll.
- All Boundary Waters Canoe Area Wilderness lakes are available for monitoring. Learn more.
- Participants in the Metropolitan Council’s Citizen Assisted Monitoring Program (CAMP) collect data at sites on many lakes in and around St. Paul and Minneapolis that this map does not show. Contact CAMP or our Citizen Monitoring Program to find out about availability if you are interested in a particular Metro Area lake.
