Sambhaji Lake, known for its beauty and richness of aquatic life in Solapur, Maharashtra. But due to urbanization, lake becomes polluted. On account of lake importance, Physical, chemical and microbiological parameters in Sambhaji lake were measured monthly at three stations (Sewage outlet, Dhobi ghat, and Ganapati ghat) in July 2013 to September 2013. The physical parameter such as temperature, color, odor, TDS, TSS and TS, chemical parameter, pH, Chlorides, sulphate, free CO2, Total hardness, dissolved oxygen, chemical oxygen demand, Phosphate, Biological oxygen demand, nitrate, oil and grease, heavy metal, microbiological parameter, total coliform, Gram negative microorganism were found. The nutrient content of lake water apparently indicated that lake had a eutrophic characteristic. Dissolved oxygen was determined as a limiting factor in lake. PH, temperature, free CO2, hardness, nitrate, was within permissible limits as per CPCB (central pollution control board). But TDS, TSS and TS, Chlorides, sulphate and BOD were above permissible limits. After microbiological analysis and MPN Gram negative E.coli were found in lake water. Eutrophic characteristic of the lake and contaminant accumulation in water will probably affect the future use of the lake. Therefore, pollution parameters must be regularly monitored and evaluated according to aquatic living and local regulations
