Mini-Hydro power generation could be planned on small-scale on existing small rivers, canals etc. as it could be beneficial in utilization of all existing water reservoirs and streams so as to generate hydro power which is renewable in nature. By this, they do not encounter the problems of rehabilitation of people and environmental problems associated with the large hydro power plants. This paper presents the case study of two potential sites namely Shahnoor and Purna in Vidarbha region of Maharashtra State in India. Here, the hydrological data of a potential site for nearly sixty years is obtained and is thoroughly studied for possible development of mini hydro power plant. The basic parameters those are to be included in feasibility report which is to be prepared for every proposed hydroelectric project are also mentioned. This paper could be well utilized for planning and irrigating land in and around rural areas.
