Abstract: Water is a prime natural resource, a basic human need and a precious national asset. Planning development and management of water resources need to be governed by national perspectives. The Govindgarh dam is one of the unique water body in India and located in south of Rewa, district in Madhya Pradesh at a distance of 20 km. from Rewa, with a longitude 24°20’25” and latitude 81°15’20”. The dam is connected with all-weather Rewa-Shahdol and Satna-Sidhi road. The dam was formed by impounding of small nalla originating from Kaimore hill. With a view to storing rain water, the Maharaja of Rewa at that time built a bandh across the nalla to form a tank in the year 1958. The shows that the lake is functioning as a carbon and nitrate removal system. Major untreated sewage influx is removed by the bio diversity of the lake. There are three major sinks namely bacterial, algal, dominated by Microcystis in summer and before winter and in winter it is dominated by Chlorella followed by Euglenophyceae member. The third sink is the macrophyte water Hyacinth, followed by Alligator weed (Alternanthera philoxeroides). Thus we can see that the surrounding borewell has 3 to 4 times increase in pollutants in ground water compared to surface water. Since there is no vegetation to remove the influx in ground water which gets all the pollutant leaching through the sediments into the water table.
