Citing data from the Flood Forecasting and Warning Section of the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), Ipo Dam in Bulacan has one gate opened at 0.20 meters (m).

Dam authorities decided to conduct emergency water discharges from the Ipo reservoir starting at 4 p.m. on Sunday due to the anticipated excess water inflow.

As of Monday, Ipo Dam’s water level still rose from 100.48 m to 100.62 m. Its spilling level is at 101 m.

One gate was also opened in Benguet’s Ambuklao Dam on Monday morning.

Ambuklao Dam’s gate had a 0.30-meter opening, narrower than the 0.50-meter opening on Sunday, as its current water level has lowered to 751.24 m from 751.46 m. 

The current level is just 0.76 m short of its 752.0-meter normal high water level. 

The water outflow from Ambuklao Dam goes down to Binga Dam, also in Benguet.

Binga Dam’s gates were already closed Monday.

Its water level has slightly gone down at 573.84 meters from 574.32 m on Sunday. Binga Dam’s normal high water level is at 575 m.

Magat Dam in Isabela also continues to release water with one of its gates open at 2 m on Monday, from two gates opened at 3 m each on Sunday.

Its water level was 188.58 m on Monday morning, up from Sunday’s 188.39 m. Magat Dam’s normal high water level is at 193 m.

PAGASA recommended residents living near river channels and low-lying communities of Isabela, particularly in the municipalities of Ramon, San Mateo, Aurora, Cabatuan, Luna, Reina Mercedes, Burgos, Naguilian, and Gamu to take appropriate action in case flooding occurs. 

Other dams being monitored by PAGASA also have higher water levels on Monday but were still far from reaching their normal high levels.

Angat Dam in Bulacan saw an increase in its water level from 200.67 m to 201.78 m.

Metro Manila and nearby provinces’ main water resource is just 8.22 m away from reaching its 210-m normal high water level.

Water levels also increased in San Roque Dam in Bulacan (from 251.96 m to 252.95 m); Pantabangan Dam in Nueva Ecija (195.42 m to 195.72 m), and Caliraya Dam in Laguna (286.5 m to 287.25 m).

Meanwhile, Quezon City’s La Mesa Dam was slightly down from 78.86 m to 78.69 m.
