Rambakan Oya Dam

The Rambakan Oya Dam is an embankment structure built across the Mundeni Aru River in Sri Lanka's Eastern Province. It holds back water in a large reservoir that supplies irrigation and drinking water to several districts in the region.

Archaeological evidence points to construction attempts at this site dating back to the third century BC, ordered by Prince Giri Abaya. The structure reflects an important chapter in Sri Lanka's ancient water management practices.

The area around the dam is connected to the history of Veddha communities who have lived here for generations. Local people use the water and surrounding land as part of their daily life and traditional practices.

The dam is located in a region best visited during the dry season when water levels are suitable for viewing. Access depends on local conditions and weather, so it is helpful to check conditions before planning your visit.

Seven smaller water reservoirs were restored as part of this project, including Polwatte Wewa and Niloba Wewa. These additional facilities show how historical water storage systems were incorporated into the region's modern irrigation networks.
