Shahpura Lake is the third biggest lake of Bhopal City, and is also known as Mansarovar Reservoir. Shahpura lake was constructed in 1974-75 under Betwa Irrigation Project. Most of the western site of lake is covered with agricultural land. The lake mainly receive overflow of an oxidation plant (Near Mata Mandir) and sewage of Mata Mandir slum area, Sahapura residential, hillock area and Academy of Administration. Due to low value of dissolved oxygen (D.O.), and with significant amount of chloride, sulphate, sulphide, ammonia, B.O.D. and C.O.D., the lake environment is reducing. It is found that enrichment of water body by the nutrients like nitrates and phosphates is accompanied by over abundance of algal bloom, shore vegetation and sedimentation, thus leading to the extinction of the lake, that will lead the eutrophication of lake.
