This study was conducted to evaluate the hydraulic performance of Kelina's small-scale irrigation scheme using selected performance indicators. Primary data like applied water measurement at head, middle and tail reach of the field, taking soil samples for determination of (moisture content, field capacity. permanent wilting point and total available water), canal flow measurement, field observation and focal group discussion and secondary data like (meteorological data, cropping data and data related to design document of irrigation scheme) were taken from the concerned institutions. After the data were taken the data were analyzed by empirical formula, CROPWAT model and Microsoft Excel. The data has been analyzed by Based on the results obtained, the study area has a clay type soil with a total available water of 122.3mm/m and a 0.54cm/hr infiltration rate. The ratio of relative water supply and relative irrigation supply was 0.92 and 0.83, respectively, which indicates a shortage of water supply since the ratio is less than one. The overall water delivery performance indicators like adequacy, equity, efficiency, and dependability have been 83, 0.11, 0.91, and 0.18 percent, respectively. The conveyance efficiency, application efficiency, deep percolation ratio, and overall scheme efficiency were 58.32, 67.57, 32.43, and 39.41%, respectively. The irrigable area was reduced by 23% and the number of infrastructures was reduced by 44.75%. Generally, the current performance of the irrigation scheme is classified as fair performance. Due to this, providing night storage, regular maintenance, and flow control structures at each off gate were recommended that enables the scheme to perform well.
