Water resources play an integral part in the life of a living being. The various water resources that are present on the earth’s surface are in the form of oceans, seas, lakes, rivers, ponds, waterfalls etc. Among these water resources Lakes and reservoirs are vital for people’s life, industrial activities and many other day to day activities. These water resources help in obtaining water for drinking after being treated. They also provide water for agriculture and industrial usage, fishery resource, flood control functions and many other activities. Due to the closed nature of lakes’, the waste material from sewage, agricultural effluents, domestic and industrial fields, gets accumulated around the surface of these water resources and once the water gets polluted, it gets strenuous to improve the quality of the water. In the study, the authors have examined different effective ways by which the quality of lake water can be improved.
