Pagasa: Angat River, Ipo Dam residents brace for floods

MANILA, Philippines — Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) tells residents living near the Angat River basin in Bulacan to prepare for possible floods.

The risk of flooding may happen due to the southwest monsoon or habagat and the spilling operations at Ipo dam in Norzagaray.

The downstream of Angat Dam, also in Norzagaray, Bulacan, is the reservoir.

In its advisory on Thursday, the weather bureau reported as of 8:00 a.m., water the level of the Ipo Dam was at 101.8 meters.

Then, Pagasa is forecasting more rain showers to be brought by habagat.

“With this, IPO DAM still conducting spilling operations with one (1) spillway gate open and a total discharge of 34.7 cms,” Pagasa reported.

The state weather bureau also predicted Angat River basin will receive five to 15 millimeters of rainfall over the next 24 hours.

“The Local Disaster Risk Reduction and Management Office (LDRRMOs) and the residents living along low-lying areas and those near the river bank of Angat River from Norzagaray, Angat, San Rafael, Pulilan, Plaridel, Calumet, Paombong, and Hagonoy are strongly advised to take appropriate actions caused by the remnants of pluvial floods (submerged roads, croplands) & fluvial floods (riverbank erosions),” cautioned Pagasa.

It earlier said despite typhoon Falcon’s (international name: Khanun) exit, it will still strengthen the southwest monsoon.

The monsoon will, in turn, bring rain showers over Metro Manila, Mimaropa, Calabarzon, Central Luzon, Cagayan Valley, and Cordillera Administrative Region.

Ipo dam, which is part of the Angat-Ipo-La Mesa Dam system, is one of the major potable water sources of Metro Manila.
