Androscoggin Lake Water Quality Archive
Androscoggin Lake Station Map
Note: This page updates throughout our monitoring season. Annual water quality reports will be available after the season is completed.
Secchi Depth 2021
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.
Temperature and Dissolved Oxygen 2021
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. After 15 meters readings are taken every other meter. For more information about temperature and dissolved oxygen in lakes and why this information is important see our water quality monitoring page.
