It was completed in January 1984 with a maximum storage capacity of 7.5 million cubic metres, an increase of about 2,500 million litres per day (MLD) from the old Ipo Dam, which was completed in December 1938, used to be located 200 metres upstream of the new dam.

The spill level of the dam is at an elevation of 101 metres and it has seven radial floodgates.

The watershed has an area of about 70 square kilometers and receives an average annual rainfall of 3,500 millimeters.

These tributaries drain into the Angat River from the eastern section of the watershed.

The Yay Regiment of the Marking Guerrillas, under the command of Col. Marcos V. Agustin, and the US Army's 43rd Division, supported by the Fifth Air Force, captured the water source intact from the Japanese defenders.
