La Mesa Dam Water Level Below Overflow Level: What You Need to Know
MANILA, Philippines — The La Mesa Dam water level remains below overflow level, officials confirmed early Wednesday morning. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) reported the water level at 80 meters as of 5 a.m., keeping it just under the critical threshold.
Pagasa stated, “Excess floodwaters in La Mesa Dam will overflow in the event that the dam water level reaches 80.15 meters.” This key update means the dam is currently holding steady but remains vulnerable to rising waters.
Flood Risks Persist in Nearby Communities
Even though the dam is below overflow level, waters released from La Mesa continue to pose flooding threats to low-lying neighborhoods along the Tullahan River. Areas in Quezon City—including Fairview, Forest Hills Subdivision, Quirino Highway, Sta. Quiteria, and San Bartolome—as well as Valenzuela’s North Expressway and La Huerta Subdivision, and parts of Malabon, remain at risk.
Residents living near riverbanks in these locations are urged to stay vigilant and prepare for possible flooding, local authorities said.
Recent Heavy Rains and Weather Outlook
The dam began overflowing Monday afternoon due to heavy rains brought by Tropical Cyclone Crising and the southwest monsoon, known locally as habagat. This overflow continued into Tuesday, prompting close monitoring.
According to sources, Metro Manila and other Luzon provinces can expect heavy to intense rainfall ranging from 100 to 200 millimeters on Wednesday as the habagat persists.
Tropical Depression Dante and Other Weather Systems
Pagasa also reported that Tropical Depression Dante is likely to strengthen into a tropical storm within 12 hours, which could further intensify the habagat’s effects. Dante was last tracked 880 kilometers east of Extreme Northern Luzon, moving northwest at 25 kilometers per hour with sustained winds of 55 kph and gusts up to 70 kph.
Additionally, a low-pressure area (LPA) inside the Philippine Area of Responsibility was spotted over the coastal waters of Calayan, Cagayan. This LPA has a high chance of developing into a tropical depression within the next 24 hours, according to weather officials.
