The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported on Monday that water levels in Angat and San Roque Dam continued to decline, falling below their normal high-water level (NHWL).
Based on the latest 24-hour dam update from the state weather bureau, Angat Dam recorded a 0.28-meter drop in water level, from 178.07 meters reservoir water level (RWL) at 8:00 AM on Sunday, 17 May, to 177.79 meters at 8:00 AM on Monday, 18 May.
San Roque Dam also registered a 0.28-meter decline, from 228.01 meters RWL on Sunday to 227.73 meters on Monday.
Other dams also posted decreases, including Pantabangan Dam (0.20 meters) and La Mesa Dam (0.01 meters), while Ipo, Ambuklao, Binga, Magat, and Caliraya dams recorded increases ranging from 0.09 to 0.58 meters.
The water level drop in Angat Dam brought it further below its Normal High-Water Level (NHWL).
The NHWL in Angat Dam is 210 meters, with the current level of 177.79 meters standing 32.21 meters below the threshold.
With rising temperatures and the ongoing dry season, water levels in dams across the country continue to decline, reflecting reduced inflows from watershed rainfall and river sources.
