Watershed of Dodokan in Lombok, Indonesia, is one of the strategic watersheds on the island of Lombok, and is a priority for rehabilitation of forest and land. This paper aims to analyse ecological water conditions in Dodokan watershed, Lombok, Indonesia, and recommends policy for improving the ecological conditions of the watershed. The results of this analysis are expected to be useful in implementing policies and programs to improve the ecological condition of this watershed, as well as to provide greater benefits for the communities around or related to this watershed. The watershed analysis focuses on five aspects, including flow regime coefficient, annual flow coefficient, sediment load, flood, and water use index. The results of the analysis show that the ecological condition of water management in the Dodokan watershed is poor, and can threaten the continuity of water resources in the Dodokan watershed. Therefore, rehabilitation activities are urgently needed.
