MANILA — La Mesa Dam continued to operate within safe parameters Thursday, with its water level remaining below the overflow status that would trigger emergency protocols, according to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa).

In an update issued at 6 a.m., Pagasa reported that the dam's water level measured 79.87 meters, providing authorities with a buffer zone above the critical threshold that would necessitate emergency spillway operations or evacuation alerts in surrounding areas.

The state weather bureau continues to monitor the dam's water levels closely, particularly as the region approaches the peak of the rainy season. Residents in communities downstream of the facility depend on regular updates to prepare for potential flooding scenarios.

La Mesa Dam serves as a critical water supply and flood control infrastructure for Metro Manila and surrounding regions. The facility's water level fluctuations are tracked continuously to balance the competing demands of water provision and flood risk management in the densely populated capital region.
