This study was conducted to evaluate the performance of Anjeb small irrigation scheme at Goncha Siso Enesie Woreda, East Gojjam zone, Amhara Region. Internal and external performance indicators were used for evaluation. The command area of the scheme covers hundred hectare. To achieve the objectives, primary and secondary data were collected. Primary data collection includes measuring discharge at different points of main, secondary, tertiary and field canals, soil moisture before and after irrigation and depth of water applied. The secondary data collection includes determination of crop types, total yields, prices of irrigated crops, area irrigated per crop per season and cost of production. Both internal and external performance indicators were used to check the performance of Anjeb irrigation scheme. From the analyses of the internal performance indicators, the conveyance efficiency, application efficiency, storage efficiency and overall efficiency were found to be 75.67 percent, 67.86 percent, 33.32 percent and 51.73 percent respectively. From the analyses of external indicators, the outputs per crop area were found as 180 quintal and 432000 birr per hectare, the value of outputs per command area of the scheme were 108 quintal and 259000 birr per hectare and the output per unit irrigation supply of 0.017 quintal and 40.77 birr per cubic meter, output per water consumed was 0.039 quintal and 93.49 birr per cubic meter. The irrigation ratio of the scheme was found to be 0.6 which means 60 percent of the command area was under irrigation during the study period. Thus, for its long term sustainability, water distribution equity, reliability and water saving, continuous monitoring and maintenance is required. Nevertheless, the results of the study can be considered in proposed water saving plans for improving the performances of the scheme. It provides to the system managers, farm staffs and policy makers a better understanding of how a system can be operated.
