At least two dams in Luzon kept their spill gates open on Thursday as their reservoirs started to rise beyond normal levels due to rains spawned by the southwest monsoon.
Shiela Schneider, hydrologist at the Philippine Atmospheric Geophysical and Astronomical Services Administration, said the water levels of Ambuklao and Binga Dams in Benguet were close to spilling levels.
As of 6 a.m. Thursday, Schneider said the water level at Ambuklao Dam reached 751.28 meters, already close to its normal level of 752 meters; while Binga Dam was 574.39 meters, near its spilling level of 575 meters.
Schneider said Ambuklao Dam opened one gate at 0.5 meter while Binga Dam opened two gates at 1.5 meters.
Ambuklao and Binga dams’ water flow downstream to the San Roque Dam in Pangasinan which can contain the water, she said.
Schneider said San Roque Dam’s water level reached 279.52 meters as of 6 a.m., or below its normal 280-meter level.
Meanwhile, the water level at La Mesa Dam in Novaliches, Quezon City reached 79.03 meters, still below its spilling level of 80.15 meters.
That at Ipo and Angat dams in Bulacan reached 100.46 meters and 210.28 meters, respectively. Their normal water levels are 100.80 meters and 210 meters.
On the other hand, the water levels at Pantabangan Dam reached 212.24 meters, below its normal level of 221 meters; Caliraya Dam in Laguna, 286.29 meters or 1.71 meters below its normal level of 288 meters; and Magat Dam in Isabela, 192.30 meters which is above its normal level of 190 meters.
