Our current concern is that nitrogen and phosphorus amounts are rising rapidly, Otherwise, to limit the growth of algae and biomass, it exists in relatively low concentrations in unmodified natural waters. This investigation aims to attempt to measure the level of eutrophication in the Hosur LakesFor this research, we chose three lakes named Chandrakudi Lake, Doddan Lake and Kelavarapalli dam. For dissolved orthophosphate, chemical oxygen need, organic nitrogen, free ammonia, inorganic nitrogen whole phosphorus and soluble oxygen, etc. some exemplars were gathered and examined. The onsite research as transparence, facts on killing fish and deterioration of the lakes conditions, etc. was also accomplished. The eutrophication rate in the lakes was measured using the Wetzel's plan. The results showed that the rate of eutrophication was very high in all three lakes, i.e. more than enough to very rich in nutrients that cause excessive plant growth, which chokes out the animal life in the water.

Momentary changes in some criteria regarding the quality of water were examined by conducting field test and laboratory examination in Cole Mere during the summer months (June, July and August) of 2013. 10 locations were chosen (inside the lake) and each was sampled nearly one month away from the other. The average surface water temperature was documented in June, July and August samplings were 14.1 °C, 21.9 °C and 18.2 °C respectively. The variations in the average temperature were numerically notable (p=<0.001). The average absorption levels of Cholorophyll a were 9.3 μgl⁻ ¹, 15.2 μgl⁻ ¹ and 39.8 μgl⁻ ¹for June, July and August respectively and there was a noticeable difference observed between the months at p=0.001. The detected momentary change and the rising levels of summer chlorophyll a absorption are exact evidence of eutrophic estate. However, no notable variations were observed regarding pH and declined oxygen between the months.
