The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Thursday announced that the quantity of water in Angat Dam is still sufficient to supply the water needs of Metro Manila which sources about 90 percent of its water from that facility.
In an interview, PAGASA Hydrologist Richard Rondain said that the water level of Angat is at 184.61 meters as of 6:00 a.m. Thursday.
”The Angat dam is still sufficient to supply water in Metro Manila and the water level isn’t critical yet and the water elevation there as still “normal,” Rondain told the Philippines News Agency (PNA).
He said Angat can provide water to Metro Manila up to the month of June.
He added that the agency expects Angat’s water level at below 180 meters or critical low by mid-May if there are no rains, but water supply is still available during this time.
Worst case scenario, he said, is if it does not rain until July.
He is advising Metro Manila residents to rationalize their use of water as Angat’s water is also used for irrigation and power generation.
“Use water wisely and people must make water conservation a habit,” Rondain said.
He said the agency expects rains to begin by the third week of May that could replenish water supply in Angat.
Built and first operated in the 1960s, Angat Dam impounds water from Angat River.
Operation in the dam prioritizes domestic water supply over irrigation if the reservoir’s water level drops below the day’s lower rule curve threshold.
Meanwhile, Rondain said that La Mesa dam in Quezon City, Isabela’s Magat Dam, Benguet’s Ambuklao and Binga dams, Pangasinan’s San Roque Dam, Caliraya dam in Laguna, and Ipo dam in Bulacan are all in normal levels despite the summer heat. PNA
