Subak Agung Yeh Sungi is an association of all the Subak Gede that use water flow of Tukad Yeh Sungi for irrigation purposes from upstream to downstream. The upstream point of Tukad Yeh Sungi was the village of Apuan, Baturiti District and for the downstream areas are in the region Beraban village, district of Kediri. The area of Subak Agung Yeh Sungi is 3,661 ha, consisting of nine Subak Gede, such as Subak Gede Bunyuh, Cangi, Tinjak Menjangan, Tungkub, Pama Palian, Mundeh, Baru Kedokan, Gadon I, and Gadon II. The purpose of this research was to determine the efficiency of water use irrigation in Subak Agung Yeh Sungi and to designe the distribution of water irrigation in Subak Yeh Agung Sungi to fulfill the concept of proportional. Based on analysis, the efficiency of water Subak Agung Yeh Sungi was 73.80% in the upstream, 84.15% in the middle and 94.21% in the downstream. The average of water use efficiency in each irrigated area was 84.05%.
