Warning over La Mesa dam in Novaliches, Quezon City

A yellow alert has been raised over La Mesa dam in Novaliches, Quezon City as its water elevation neared the spilling level due to isolated rainshowers, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Thursday.

Oyie Pagulayan, PAGASA Hydrologist, said the dam’s water level stood at 79.35 meters as of 6 a.m. Thursday, or just 0.80 meters below its spilling level of 80.15 meters.

“Tumaas ‘yung water level ng La Mesa dam due to isolated rainshowers, but we continue monitoring and once the water level reaches 79.53 meters, it will be raised to red alert status,” Pagulayan said.

She said that the dam has no gates and the excess water spills into the Tullahan River, which flows through the northern part of Quezon City, including the Fairview and Novalihes areas, as well as the cities of Malabon, Valenzuela, and Caloocan.

Meanwhile, as of 6 a.m. Thursday, the water level of Binga dam in Benguet reached 571.89 meters or below the dam’s 575-meter water level and opened one gate at 0.3 meter.

Binga’s water flows downstream to the San Roque dam in Pangasinan, which can contain the water spillage.

San Roque Dam’s water level stood at 269.61 meters as of 6 a.m. Thursday, or way below its normal 280.00-meter level.
