Threats of massive flooding still remain a threat in parts of Luzon as the five major dams in Luzon have been releasing excess water due to the heavy rains brought by Typhoon “Ulysses.”
Richard Orindain of the hydro-meteorological division of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the five dams – Angat, Ipo, Ambuklao, Binga and Magat – have been discharging water to avoid their water levels from reaching critical status.
Even before Ulysses made landfall, the Ambuklao, Binga, and Magat dams released water on Tuesday as the typhoon approached the Philippine Area of Responsibility.
“Such preemptive water release is in anticipation of rainfall that ‘Ulysses’ may bring,” PAGASA hydrologist Rosalie Pagulayan said.
She said the spilling operations aim to ensure that water in the dams will remain at elevations that would not compromise the facilities’ structural integrity.
Binga has an outflow of 494.71 cubic meters per second and areas to be affected by its discharge are Barangays Dalupirip and Tinongdan in Itogon, Benguet.
Magat’s water release will affect the towns of Ramon, San Mateo, Aurora, Cabatuan, Luna, Reina Mercedes, Burgos, Naguilian and Gamu in Isabela.Angat and Ipo dams’ water release will affect the towns of Norzagaray, Angat, San Rafael, Bustos, Baliuag, Pulilan, Plaridel and Hagonoy in Bulacan.
