Hydropower is one of the major and sustainable energy production centers across the world. Energy production has several challenges and uncertainty to alleviate poverty in our country. The main aim of this study was selecteding the hydropower potentials of Temcha watershed with integrated approaches of using GIS and hydrological models (SWAT). For the hydropower potential selection, it was used weather (metrological), hydrological and geospatial data. The result shows that a high discharge amount with a corresponding head has been identified in the upper course of the river and its associated values 300m3/year. In the middle course of the river, the power potential would be 126 MWmw/year. Generally, the overall hydropower potentials of Temcha watershed were 2500 MWmw/year.
