This study conducts the thought of comparative performance indicators by using some internal and external process indicators as tool in the two selected schemes (lower Fetam and Leza) which were in the Amhara region west Gojjam zone. The evaluation carried at field levels were conveyance, application, and storage process indicators and the minimum sets of comparative indicators were used to compare schemes those are four from agricultural output two from water use and one from physical sustainability indicators. Collecting primary and secondary data of each irrigation schemes has been carried out. In the evaluation of irrigation water use efficiency at field level nine Farmers field were selected from each irrigation scheme with their site (from the Head, middle and lower water users). The average conveyance efficiencies at point of measurement were 78.67% and 81.14% for Lower Fetam and Leza schemes. The average application efficiencies of the selected farmer‟s field from the scheme were 64.96% and 58.8%, the storage efficiencies were 23.37% and 27.98% and also over all efficiencies were 51.75% and 47.71% for Lower Fetam and Leza schemes. The minimum sets of comparative indicators were used to compare schemes those are four from agricultural output two from water use and one from physical sustainability indicators. From the analyses of the comparative performance indicators, the result of water use indicator RWS and RIS were 1.81and 1.61 for Lower Fetam and 1.22 and 0.91 for Leza irrigation scheme respectively. The values of IR were 0.41 and 0.43 for Lower Fetam and Leza respectively. This implies that higher amount of water were diverted than the crop demand and in both scheme they cultivate less than fifty present of the total irrigable land in a season in both scheme. Outputs per cropped area of the two projects were 59,055.97birr/ha for Lower Fetam and 55, 5097.45birr/ha for Leza and the value of the output per command area were 24,409.8birr/ha for Lower Fetam and 23,734.28birr/ha for Leza. The outputs per unit Irrigation supplies in the Lower Fetam and Leza scheme was 1.46birr/m3 and 1.83birr/m3. In the other case the Outputs per water consumed were 7.23 birr/m3 and 6.41birr/m3 for Lower Fetam and Leza scheme. According to the evaluation carried Lower Fetam has relatively performed better than Leza but it is a little bit it needs improvement. The discharge in both schemes was enough if it is managed well so there is no shortage of water, especially Lower Fetam scheme has the capacity to expand and to provide irrigation to the surrounding community which depends on rain-fed agriculture.
