Present paper embodies limnological investigation of Laharpur reservoir Bhopal, (M.P.) India which was carried for a period of one year 2009-2010.It was constructed in the South west of Bhopal city for the irrigation purpose. At the time of construction it was in the out of city but now, with the expansion of city it is in between the residential areas. Due to the developmental activities and occupancy in the city this reservoir is almost contaminated. Other than this it also receives city sewage, industrial wastes run-off and agricultural waste fields. This untreated water poses a serious threat to health of humans and animals so there is an urgent requirement for its study of extent of pollution which will help us in further management and conservation. Physico-chemical characteristics of Laharpur reservoir was studied for a period of 12 months from August 2009- July 2010. In view of above, an attempt was made to study certain limnological parameters such as Temperature, pH, conductivity, turbidity, total hardness, Ca and Mg contents, total alkalinity, BOD, and COD etc. For examination of above all mentioned parameters American Public Health Association (APHA), American Water Works Association was made. Present research work concludes that Laharpur reservoir which was basically made for irrigation point of view is now highly polluted water body due to continuous discharge of municipal sewage.
