Water level at Angat Dam continues to increase and is now 161.86 meters as of Thursday morning or 1.86 meters above the 160-meter critical level due to the recent monsoon rains over the watershed area in Norzagaray, Bulacan.


Based on the monitoring of Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), Angat Dam’s level rose to 161.86 meters on Thursday morning, higher by 0.78 meters from last Wednesday’s 161.08 meters.

While it is already higher than its 160-meter critical level, the National Water Resources Board (NWRB) has retained the 36 cubic meters per second (cms) water allocation until such time that the Angat Dam’s level is sufficient enough to supply the regular demand of consumers in Metro Manila and nearby areas.

The water reservoir’s level is still way below its 180-meter minimum operating level and 210-meter normal high water level.

NWRB Executive Director Sevillo David Jr. said that if the water level at Angat Dam further rises, the agency may consider increasing the water allocation for water concessionaires.

Meanwhile, the weather bureau said Visayas and Mindanao will continue to experience some rains due to the trough or extension of a low-pressure area (LPA) east of the country, while Luzon will have fair weather condition due to a weak southwest monsoon or habagat.

PAGASA weather specialist Ariel Rojas said the LPA was estimated at 520 kilometers east-southeast of General Santos City as of Thursday morning. It is less likely to develop into a tropical cyclone and may dissipate within 24 to 36 hours, he said.

But the trough or extension of the LPA will continue to bring scattered rain showers and thunderstorms over Visayas and Mindanao. Metro Manila and the rest of Luzon will only have isolated rain showers due to the weak effect of habagat, Rojas said.

PAGASA advised the public that rains, especially during severe thunderstorms, could trigger possible flash floods or landslides over low-lying and mountainous areas.
