The Rambakan Oya Dam is an embankment dam in Maha Oya, Eastern Province, Sri Lanka. The reservoir was designed and constructed by the Sri Lanka Mahaveli Authority and currently functions under the direction of the Ministry of Irrigation and Water Resources Management.[1] It has been created by building an Earthen dam which is about 1,225m in length across the Mundeni Aru river.[2]

The Rambakan Oya reservoir project is a multipurpose irrigation project which is commissioned to find a solution for the drinking water issue and irrigation problems in the area.[3] It is the 10th zone of Mahaweli Development scheme and located bordering Badulla, Monaragala and Ampara districts.[4]
