La Mesa Dam is nearing its spilling level as persistent rains continue to raise its water level, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported.
According to PAGASA, the dam’s water level has risen to over 79.90 meters, driven by the ongoing southwest monsoon or “habagat.” If the water level reaches 80.15 meters, the dam is expected to overflow.
The potential overflow could impact low-lying areas along the Tullahan River in Quezon City, including Fairview, Forest Hills Subdivision, Quirino Highway, Sta. Quiteria, and San Bartolome. Additionally, Barangay Ligon, North Expressway, La Huerta Subdivision in Valenzuela, and parts of Malabon are also at risk.
Residents in the vicinity have been advised to evacuate as a precautionary measure while PAGASA continues to monitor the situation closely.
La Mesa Dam, located in Quezon City, Metro Manila, is a critical component of the water supply system for the Greater Manila Area.
It primarily serves as the main reservoir for raw water coming from Angat Dam, which is then processed and distributed to Metro Manila and nearby areas.
The dam also plays a crucial role in flood control, especially during the rainy season when heavy downpours are common.
Due to its location and function, the dam’s water levels are closely monitored, particularly during periods of intense rainfall, to prevent potential flooding in downstream communities.
