Data Visualizations - "Vizzes"
Use these interactive Vizzes to delve into Maine's lakes! Learn about their plant & animal plant communities; water quality; and geography & landscape characteristics.
New visualizations are added to this collection from time to time. Let us know if you have any suggestions for new Vizzes!

Fish species in Maine lakes
Map displays fish species lists for each surveyed lake. Data are from IF&W (2007 data export). Fish species lists for some lakes may have changed since 2007 as a result of illegal stockings or natural range expansion. For more current data, consult maps on IF&W website.

Loon counts: Audubon surveys
For over 34 years, citizen scientists have helped collect invaluable data that has allowed Maine Audubon to chart the progress of the state’s loon population over time. Explore an interactive map for Loon Count results on Maine's lakes from 1983 through today. Zoom in to an area to see lake pins. Then click on a pin to see the loon data. Alternatively, search by lake name.
Water Quality
Maine's 50 clearest-water lakes in 2017
Use this interactive graphic to explore where the 50 lakes with the highest Secchi transparencies are located
Secchi transparency in Maine lakes
Explore water transparency in over 1000 lakes across Maine
Secchi data - overall mean values
Mean values of Secchi depth (a measure of water transparency) represent overall means across all years with data. Number of data years varies by lake. Data are courtesy of Maine DEP & LSM.
Water chemistry data - overall mean values
Explore an interactive map showing water chemistry data in over 1000 Maine lakes.
Number of years with lake data (Secchi, TP, Alk)
Map displays number of years for which data are available for the following water quality parameters in Maine lakes: Secchi transparency, phosphorus and alkalinity.
Near real-time water quality data for selected lakes
Map displays near real-time Secchi transparency data for selected Maine lakes. (Note: data collection & display are from a pilot LSM project, started in 2014 and which will continue in 2015.)
