Ipo, Ambuklao, and Binga dams in Luzon on Wednesday, July 28, continued to release water from their reservoirs due to excessive rainfall from the southwest monsoon or “habagat.”

Based on the latest monitoring of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), Ipo Dam in Bulacan has one gate opened at 0.15 meters (m).

Dam authorities started to conduct emergency water discharges from the Ipo Dam reservoir last Sunday, July 25.

As of Wednesday, Ipo Dam’s water level still rose from 100.76 m to 100.92 m. Its spilling level is at 101 m.

Five gates were also kept open in Benguet’s Ambuklao Dam on Wednesday morning.

Ambuklao Dam’s gates had a three-meter opening as its current water level continued to increase from 751.83 m to 751.98 m.

The current level is just 0.02 m short of it is 752.0-meter normal high water level.

Binga Dam in Benguet also had six gates opened on Wednesday morning.

Its water level slightly went up from 574.44 meters to 574.70 m. Binga Dam’s normal high water level is at 575 m.

The water outflow from Ambuklao Dam goes down to Binga Dam, and further down to San Roque Dam in Pangasinan.

PAGASA’s monitoring showed that the water level in San Roque Dam significantly increased from 233.70 m to 236.12 m but still far from its 280-m normal high water level.
