The purpose of this study is to determine the physical conditions of irrigation schemes, their contributions to national revenue, to diagnose problems of each scheme and make some recommendations for better management.

In this study; according to the 2000s irrigation results, comparative performance indicators such as output per cropped area output per unit command, output per unit irrigation supply, output per unit water consumed and relative water supply developed by IWMI (International Water Management Institute) which provide comparable analysis of irrigation performance among irrigation schemes were applied on 21 turnover schemes (irrigation associations, village authorities, municipalities) and system performance was evaluated.

According to the result of study, output per cropped area output per unit command, output per unit irrigation supply, output per unit water consumed and relative water supply was calculated 424-3957 $/ha ,853-6382 $/ha, 0.07-0.45 $/m3, 0.05-1.51 $/m3 and 0.42- 6.06 respectively.
