MANILA, Philippines - The Ipo dam in Bulacan has started releasing 30 cubic meters of water per second after the water level already reached spilling level.

Dr. Susan Espinueva of the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) Hydrometeorology Section said the overflow is now being absorbed by the Angat spillway and by La Mesa Dam in Quezon City.

Espinueva assured that Angat water levels remain below the spilling level of 210 meters. Currently, it is at 193.35 meters.

On the other hand, La Mesa Dam is just 0.37 meters away from its spilling level of 80.15 meters.

Aside from Ipo, Binga dam in Benguet has also opened its gates and has been releasing 100 cms of water.  The overflow goes to San Roque which is still way below the spilling level.

Espinueva said they have to carefully monitor Angat and Magat due to expected rains in the coming days.

A new low pressure area is expected to enter the Philippine area of responsibility tomorrow and there is a high possibility that this will develop into typhoon Falcon. It is expected to follow the path of Egay and will bring much rain due to the southwest monsoon.

Espinueva said this may cause Angat and Magat to spill and is advising nearby communities to be on the alert.

Usually, around 8 municipalities in Bulacan and around 9 in Isabela get inundated whenever the Angat and Magat dam spill.
