Abstract: “Mansagar Lake”, popularly known as “Jalmahal” is located in the heart of Jaipur City and is a very renowned Ecologically important Wetland Site too. The Mansagar Lake is a manmade water body, created by damming Darbhawati river on the northern side of the Nahargarh Fort around 1610 A.D. by Raja Man Singh First, the then ruler of Amerfor irrigation and recreation. In 1962, the Sewage from the Walled City of Jaipur was diverted into the lake as it was no more used for recreation and the palace has been abandoned. Pollution problems presides in the Lake due to the Inflow of Waste Water by the increasing flow of partly treated wastewater and untreated wastewater with severe contamination. All this leads to the alteration of the various Physico Chemical Parameters of the water body as well as the accumulation of the heavy metals resulting in the various phenomenon like Eutrophication of the water body, Deposition of Silts and the pronounced deterioration of the Water Quality. Characteristics of water bodies influence the quality of water individually and in combination with various pollutants, thereby, affecting the living organisms present there (Srivastava et al., 2003; Smitha et al., 2007).. The Physico-Chemical study conducted about Water and Soil revealed variable ratios, which include diverse range of Ph, EC, TDS, Chloride, Hardness, Alkalinity, Acidity, D.O., BOD, Fluoride and, Nitrate of the WaterBody alongwith thePhysico-Chemical Characteristics of the Soil Bed of the Lake which includes the parameters like Ph, EC and, others include its Moisture Content and the presence of the percentage of Organic Matter and Organic Carbon in the soil.
