Abstract: In last few decades ever increasing population and unplanned urbanization have posed serious problems of sewage disposal and contamination of surface waters like lakes, reservoirs, dams, rivers etc. Most of these water resources also get contaminated due to weathering of rocks, leaching of soils etc as natural phenomena, ultimately causing nutrient enrichment in these surface water resources. Land use changes and the increase use of fertilizers in modern agricultural practices with subsequent leaching to watercourses, rivers and lakes, has further increased the risk of eutrophication and loss of biodiversity, finally deterioration in water quality (Pani, 2017).Therefore there has been a growing need for regular water quality assessment to understand the existing status of the water body so as to adopt necessary mitigative and conservation measures for abatement of pollution. Water quality can be assessed by various parameters such as BOD, temperature, electrical conductivity, nitrate, phosphorus, potassium, dissolved oxygen, etc. along with heavy metals such as Pb, Cr, Fe, Hg, etc. which are of special concern because they produce water or chronic poisoning in aquatic animals. Harmful algal blooms are becoming increasingly common in freshwater ecosystems globally. Pollution by plastic debris is an increasing environmental concern in water bodies, where it affects open-water, shoreline and benthic environments (Bhateria and Jain, 2016). Hence keeping this in mind the water quality of Kaliasote Dam which is one of the important Dams of Bhopal was analyzed during the period 2015-2017 to understand the present status of water quality with reference to nutrient enrichment from both the autochthonous and allochthonous sources. The results of various parameters indicate that the water of the dam is moderately polluted and can be used only for domestic and irrigation purposes after treatment as per standard prescribed by CPCB.
