Working towards our vision of a healthy aquatic ecosystem supporting - and supported by - the people of Nepahwin Lake Watershed.
Secchi Depth (Water Clarity)
Secchi depth readings are a measurement of water clarity; the depth at which a specialized tool (Secchi Disk) disappears to the naked eye. Readings are taken by NLWSG volunteers on a bi-weekly basis in order to track changes in water clarity.
For more information on how and why we take these measurements, visit our Lake Partner Program page.
