The power of Volunteers!

The power of volunteer-collected data is on full display in these state-wide online maps! An army of volunteers across the state collects data so that that we can learn about the health of our state's waters. https://experience.arcgis.com/experience/7be28eb70b354e4d92e47fd14ab405df

Click on any lake displayed on the map to see the results of the most recently water clarity trend analysis. Trends use all historical data per stream site or across a full lake to determine if water clarity is increasing, decreasing or staying the same. Not all lake or stream sites have enough data to determine if a trend is present.
