Due to rains spawned by southwest monsooon enhance by tropical storm Maring, at least four major dams in Luzon opened their gates on Monday.

Edgar Dela Cruz, Hydrologist of Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa), in an interview said these included Ipo in Bulacan, Ambuklao and Binga in Benguet, and Magat in Isabela province.

Dela Cruz that as of 6 a.m. on Monday, the water level at Ambuklao dam reached 749.71 meters or below the high level of 752.00 meters, while Binga dams water level was at 574.13 meters, almost its normal high level of 575.00 meters.

He said that Ambuklao dam opened five gates by 7.5 meter while Binga dam opened six gates by 9.5 meters.


He also said Ambuklao and Binga’s waters flow downstream to the San Roque dam in Pangasinan, which can contain the spillage. San Roque dam’s water level stood at 257.70 meters as of 6 a.m. Monday, or way below its normal 280-meter level.

Dela Cruz also said one gate of Magat dam in Isabela remain opened by two meter as its water level reached 191.42 meters lower than 191.74 meters on Sunday.

Magat Dam’s high water level is 193 meters.

The opening of the flood gates in these three dams is a precautionary measure, he said.

He said Ipo dam also kept one gate open at 0.3 meter as its water level rose to 100.28 meters from 100.08 meters Sunday and this is over the dam’s high water level of 100.2 meters.

Dela Cruz also said that La Mesa Dam in Quezon City is under red alert as its water level rose to 79.69 meters, near the high water level of 80.15 meters.

The dam has no gates and the excess water will spills and flows into the Tullahan River, which flows through the northern part of Quezon City, including the Fairview area, as well as the cities of Malabon, Valenzuela, and Caloocan.

“Kung mareregulate ng Ipo ang pagbigay ng tubig sa La Mesa hindi aapaw pero kung hindi naregulate at ganito ang weather natin for sure aapaw yan,” Dela Cruz explained. PNA
