Station 1 Secchi Depth 2018

Station 1 Secchi Depth 2019

Secchi depth readings measure transparency by recording the level at which a black-and-white disk disappears from sight as it is lowered beneath the surface of the lake. See our water quality monitoring page for more information.

Station 1 Temperature and Dissolved Oxygen 2018

Station 1 Temperature and Dissolved Oxygen 2019


These readings are obtained as an electronic sensor measures temperature (in degrees Celsius) and dissolved oxygen (in mg/L or ppm) as it is lowered at one meter intervals starting at the surface of the lake. For more information about temperature and dissolved oxygen in lakes and why this information is important see our water quality monitoring page.

Thank you to all of the volunteers who helped us collect these data!
