Abstract
The results of these studies indicate that the first diatom flora developed at the 13‐meter level. The flora at 12 meters increased. At the 11‐ and 9‐meter levels the lake became increasingly eutrophic. Both plankton and benthic forms were present. At the 8‐ and 7‐meter levels the lake was in a transitional stage from lake to bog conditions. From 6 meters to the surface bog conditions were present.
