Online published on 23 May, 2013. Abstract Lake water ecosystem is greatly influenced by the seasonal variation in physic-chemical parameter and also due to the human interference and activities. Upper Lake (Bhojtal), Bhopal, India, is main source of drinking water to half of the population of Bhopal city, was studied to find out the seasonal variation in and correlation of physico-chemical and bacteriological parameter during 2010-12. Seasonal variation of parameter was observed with great correlation with bacterial properties. Increased turbidity, TDS, BOD and COD values indicated the high load of organic pollution and therefore the bacterial load. Catchment area of Lake under old Bhopal city was highly polluted with abiotic and biotic (TVC, TC and hemolytic bacteria) as compared to other sites of lake. Year wise increased pollution at other sites of lake is of great concern due to urbanization and increased population, resulting into increased inflow of sewage. The increased population of total coliform and hemolytic bacteria is of great concern which is making the water unhealthy for drinking purpose before the proper treatment.
