The Valvan dam is constructed on Indrayani River for irrigation and hydroelectric power plant. It flows. In the catchment area of Indrayani River, population is rapidly increasing, because of best connectivity of roads and railway transport, many educational hubs and job opportunities. Many villages and four Municipal councils release their untreated sewage wastes into the Indrayani River. At Indori and Dehu collection sites all the physiochemical parameters have high values and this water is not found suitable for drinking and other purposes. The river is becomes eutrophic, at many places water surface is covered with aquatic vegetation such water hyacinth and Vallisneria. Therefore, Indrayani River is getting polluted due of domestic and industrial discharges; there is record of death of fishes, mostly Mahseer. Copyright@ International Science Community Association
