Ipo Dam in Bulacan to release water

MANILA, Philippines – The Ipo Dam is set to release water to prevent overflow from the overnight rains.

“As of 11 a.m., the elevation of Ipo is at 100.75. We were advised this morning around 8 a.m. that as soon as they reached 100.80 meter elevation they have to open one gate at 50 centimeter opening, that's about 60 cubic meters per second,” said Dr. Susan Espinueva, head of the Hydrometeorological Division of weather bureau PAGASA.

The news about the planned release of water was relayed to radio dzMM by Eng. Hermy Medrano of the Ipo Dam on Saturday.

The Ipo Dam is located in Norzagaray, Bulacan, but both Medrano and Espinueva explained that the spill will not affect already flooded areas in the province.

“I would say that this outflow is very minimal and will not affect the existing flooding now in Bulacan area,” Dr. Espinueva said.

As of the latest status of major dams in Luzon, 4 are still open and releasing water. These are Ambuklao, Binga, San Roque and Magat dams.

Magat Dam
Ramon, Isabela
192.82 meters (open)
Mankayan, Benguet
751.81 meters (open since ‘Pedring’)
Bokod, Benguet
574.76 meters (open)
San Roque
San Manuel, Pangasinan
281.11 meters (open)
Pantabangan, Nueva Ecija
210.04 meters (closed)
Norzagaray, Bulacan
213.36 meters (closed)
Norzagaray, Bulacan
100.75 meters
La Mesa
Quezon City
79.59 meters
Cavinti, Laguna
286.34 meters

“All these data were observed at 11 a.m. today,” she said.

Since watersheds are saturated and also due to the passage of typhoons Pedring and Quiel, Espinueva said they expect any amount of rain to trigger an increase in the water levels of these dams.

“They should be always on alert because we have this low pressure area. Although very minimal is the outflow of Ipo, it will not affect so much. It will not even increase ‘yung level ng river within Angat,” she said.

As of 11 a.m. PAGASA said the Low Pressure Area (LPA) was spotted 50 kilometers north of Coron in Northern Palawan, embedded along the Intertropical Convergence Zone (ITCZ).

“Due to the combine effect of these weather systems, the whole country will have cloudy skies with scattered rainshowers and thunderstorms, becoming widespread rains over Central and Southern Luzon and Western Visayas which may trigger flashfloods and landslides,” PAGASA’s weather advisory stated. -- With reports from ANC and radio dzMM
