This distribution map represents both lake and stream data for this species. Background layers in the map are major rivers and watersheds.
The scatter plot to the right of the map shows, for lake populations, the distribution of each species across lake size (surface area) and elevation gradients. Lakes containing the species are indicated by purple squares. Other surveyed lakes which do not contain this species are shown as light blue dots.
Data source: MDIFW and other sources as compiled in Maine Aquatic Biodiversity Project database.
