Dams are structures made of earth fill, rock fill, concrete, and/or masonry designed to retain and store water. Their purposes include supplying irrigation water, drinking water, flood control, and power generation.
As of October 2022, 215 dams operated across 17 Indonesian provinces are managed by the Ministry of Public Works and Public Housing (PUPR).
The highest number of dams is located in West Nusa Tenggara, with 74 units. The number of dams in other provinces is fewer, as detailed in the graph.
The PUPR Ministry aims to complete the construction of 13 new dams throughout 2023, namely:
1. Rukoh Dam (Aceh)
2. Keureuto Dam (Aceh)
3. Lau Simeme Dam (North Sumatra)
4. Karian Dam (Banten)
5. Cipanas Dam (West Java)

10. Temef Dam (East Nusa Tenggara)
11. Sepaku Semoi Dam (East Kalimantan)
12. Pamukkulu Dam (South Sulawesi)

"The main target for 2023 is also the construction of dams and lakes, with a budget allocation of Rp 14.20 trillion used for the continued construction of the 13 targeted dams," said the Director General of Water Resources of the PUPR Ministry, Jarot Widyoko, in his press release (5/9/2022).
"We are also carrying out the construction of new dams, namely Jenelata and Riam Kiwa, which are funded through foreign loans. Then there is the Mbay Dam in East Nusa Tenggara, the construction of which began in 2021," he continued.
