The dip in the reservoir’s water level happened as parts of the country experiences heavy rains due to “Falcon.”
PAGASA also noted a drop in the water levels of other dams except for Ambuklao in Benguet and San Roque in Pangasinan.

At least 1,160 mm is needed to attain the dam’s normal high water level of 210 meters.
The STAR reported that “Falcon” is expected to bring 50 to 100 mm of rain over Bulacan, where the reservoir is located.
Angat Dam provides more than 90% of the potable water needs of Metro Manila residents who are currently experiencing rotational service interruption after the National Water Resources Board slashed the allocation for Maynilad and Manila Water to 36 cubic meters per second.
