Tips for using the map

- Click on lakes, stream segments, or stream sites to view exact location descriptions.
- All Boundary Water Canoe Area lakes are available for monitoring. Learn more on the Other volunteer opportunities page.
- Participants in the Metropolitan Council’s Citizen Assisted Monitoring Program (CAMP) collect data at many Twin Cities lakes not shown on the map. Contact CAMP or our program if you are interested in a specific metro-area lake.
