Expanding efficient irrigation development on various scales is one of the best alternatives to provide reliable and sustainable food security. However, many irrigation schemes in developing countries in general and particularly in Ethiopia are performing below capacity. This study was conducted to evaluate the performance of wosha soyama irrigation scheme at Wondo Genet South Nation Nationality and People Regional State, Ethiopia. The evaluation carried out using standard technical performance indicators including conveyance, application, water storage, water distribution uniformity efficiency and deep percolation loss were used at the head, middle and tail reach of the scheme. The study shows that application efficiency was very low which is 48.2% due to higher water loss through deep percolation. Conveyance efficiency, water storage, water distribution uniformity efficiency, and deep percolation loss were revealed 55.6, 89.8, 91.7 and 51.8%, respectively. The overall efficiency was also below the desired level which is 26%. Based on the above observation, adoption of water saving practices such as deficit irrigation, surge and cutoff application to improving application, frequent maintains of water conveyance system can enhance the conveyance efficiency of the scheme.
