The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that water levels in Angat Dam and several other major dams across the country have increased despite low levels in previous days.

PAGASA's 24-hour dam monitoring report as of 8:00 a.m. on Thursday [July 30 2026] revealed that water levels increase in Angat Dam in Bulacan, La Mesa Dam in Quezon City, Ambuklao and Binga Dams in Benguet, Magat Dam on the border of Ifugao and Isabela, Pantabangan Dam in Nueva Ecija and Caliraya Dam in Laguna. 

The Angat Dam, known for supplying waters in Metro Manila, has reached 3.48 meters increase from 150.85 meters Reservoir Water Level (RWL) on Wednesday [July 29] to 154.33 meters on Thursday [July 30].

Meanwhile, nearly one meter increase was observed in Ipo Dam with 0.40 meters rise from 99.60 meters to 100 meters. 

La Mesa Dam, which followed the Angat-Ipo-La Mesa water system, recorded 79.25 meters RWL from the previous 79.19 meters, rising only 0.06 meter in its water level.

The state weather bureau also observed water level increase in other dams including Binga Dam with 0.36-meter rise from 570.32 to 570.68 meters and Pantabangan Dam with 0.22-meter increase from 175.98 to 176.20 meters.
