Dadadahalli Lake has the highest organic pollution
while Kalale Lake and Makanahally Lake were heavily polluted. Species of Euglena and Scenedesmus were
the most tolerant species. Algae were highly nested in Dadadahalli Lake, Dalvoi Lake, Karanji Lake and were
the most hospitable sites for growth of algae while most of the other lakes had idiosyncratic species. The
matrix fill was low (59.5%) and the system temperature was warm (34.22o
) indicating poor distribution of
algal species. The use of modern tools in determining levels of organic pollution in lake ecosystems has been
discussed.
