Batu dam is a flood control and water supply dam constructed under the Kuala Lumpur Flood Mitigation Project.
Its construction was completed in 1987.
The dam is located immediately downstream of the confluence of Sungai Batu and Sungai Tua which is about 16km upstream of the city centre of Kuala Lumpur.
Currently, Puncak Niaga is abstracting water direct from the dam for domestic and industrial water supply to some parts of Kuala Lumpur.
The main project components are an earthfill main embankment, a spillway and outlet works.
