Performance of Shina-Hamusit and Selamko Irrigation Scheme of Dera and Farta district, respectively in South Gondar zone, Ethiopia were evaluated using some selected comparative indicators, classified into four groups, namely, agricultural, economic, water-use and physical performance by International Water Management Institute (IWMI). Overall activities in primary data collected included: field observation, interviewing beneficiary farmers, discharge measurements in the canals. In addition to primary data, secondary data were collected from the secondary sources, and included total yields, area irrigated per crop per season or per year, crop types, and cropping pattern. The results of performance with respect to both land and water productivity indicate that Shina-Hamusit scheme performs better. Analyses of water-use performance showed that relative water and relative irrigation supply values were calculated as 1.55 and 1.31 at Shina-Hamusit and 1.87 and 0.81 at Selamko, respectively, indicating that water distribution is not tightly related to crop water demand. Physical performance, evaluated in terms of cropping intensity, irrigation ratio and sustainability of irrigated land, were good. Economic performance indicators showed that Selamko scheme had a serious problem about the collection of water fees, but not at Shina-Hamusit.
