The water level in Angat Dam went up on Friday, Sept. 1 due to heavy rains from the cyclone-enhanced southwest monsoon or “habagat,” said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In the PAGASA’s 6 a.m, bulletin, Angat Dam’s water level increased by 1.01 meters, from 198.14 meters on Thursday, to 199.15 meters on Friday.
The dam's current water level, however, is still below the 210-meter normal high water level during the rainy season.
Meanwhile, the Ipo Dam, which is downstream of Angat Dam, is still releasing excess water as of Friday morning.
The Angat and Ipo dams are in Norzagaray, Bulacan.
“The water level of Ipo Dam as of 8 a.m. is 100.96 meters and continuously rising due to the expected rains caused by the southwest monsoon. With this, Ipo Dam is still conducting spilling operations with one spillway gate open and a total discharge of 35.50 cms (cubic meters per second),” PAGASA said in a flood advisory issued at 9 a.m.
Ipo Dam has a spilling level of 101 meters.
PAGASA urged residents living in low-lying areas and near the riverbanks of the Angat River in Norzagaray, Angat, San Rafael, Bustos, Baliuag, Pulilan, Plaridel, Calumpit, Paombong, and Hagonoy in Bulacan to be vigilant as the river’s level may rise.
