Angat Dam's water level was more than three meters above its 212-meter spilling level, prompting dam operators to release excess water from the reservoir Monday morning.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) monitored the level of Angat Dam at 215.90 meters as of 9 a.m., which is higher by 2.3 meters from last Sunday's 213.60 meters.

Moreover, Angat Dam's level is currently 3.90 meters above its 212.0 meters normal high water level.

To protect its integrity and structure, Angat Dam started to release 289 cubic meters per second of excess water around 9 a.m.

Most of the water discharged from Angat Dam goes to Ipo Dam, which has a current water level of 99.90 meters.

Ipo Dam's normal high water level is 101 meters.

The discharged excess water from Angat Dam and Ipo Dam flows through the Angat River.

Hydrologist Max Peralta said some of the discharged water helps to supply the domestic water and irrigation requirements, although some of it may affect low-lying communities in Bulacan.

PAGASA advised those living in low-lying areas of Norzagaray, Angat, San Rafael, Bustos, Baliuag, Pulilan, and Plaridel in Bulacan to take appropriate action in case flooding occurs.

Meanwhile, Magat Dam operators have reduced the number of spillway gates that are releasing water from the reservoir in Isabela Monday.

From six gates last Saturday, three gates with a total opening of six meters are currently discharging 1,686 cubic meters per second from the Magat reservoir as of 10 a.m.

PAGASA said the level of Magat Dam was 190.93 meters Monday morning, slightly lower than the 191.32 meters last Sunday and lower than its 193-meter normal high water level.
