There are diversity of alga and its abundance exhibiting seasonal variations in productivity.
Pollution levels and types of causative factors changes from place to place as like industrial
wastage, dumping of solid waste by several cities and towns. The pollution index is based on the
relative number of total points scored by each alga. These are mostly near to human civilization, so
it is easily contaminated with eutrophication. The temperature vary throughout the study area in
rainy season 27-35,in winter 16-25,summer 35-43. Water temperature also one of the major
determinant factors for the growth of phytoplaktons and zooplanktons. 74 algal species occurred,
genera 46. Observation made that, the month of June to September Chlorophyceae members
dominant over the other classesin that Pediastraum, Closterium, Casmarium, Scenidesmus,
dominant other species. Bacllariophyceae members particularly Navicula appear good above
period. The major threats to lentic ecosystems by bathing using of soaps, washing clothes, cleaning
vehicles (source of automobile discharge) dumping of garbage, hospital wastage, pesticide remains
etc. This is done by only ignorance of illiterates, but some activities are as a functional.
