INTRODUCTION Dams are critical in terms of population life support and ensuring sustainable economic development. Dams not only for flood control but also provide water for some mutipurpose activities such as hydropower, irrigation water supply, domestic consumption, industrial water use, tourism, aquaculture, navigation, etc. Sutami dam is one of the large dams located in Brantas River Basin. Sutami dam (locally named as Karangkates dam) located at Brantas River Basin in Indonesia. The dam is a multifunction dam, which is used for flood control (with the capacity of 1,650 m3/sec), providing irrigation water supply for 34,000 hectares, and also to generate hydro power plant with installed capacity of 3 x 35 mW. Sutami dam has 180 million m3 storage capacity (based on 2016 bathimetry survey) and 1,500 hectares reservoir surface area. The public safety around dam issues surrounding the safety concerns for Sutami dam existed from its beginning of operation because of its critical water storage capacity, structures and massive human activities’ surrounding it. This paper addresses some of those public safety requirements throughout the facility and more specifically following the more recent safety risk assessments and mitigation strategies implemented to meet the anticipated safety requirements nowadays. 1246
