MANILA — La Mesa Dam's water level has fallen below its overflow threshold while remaining elevated above critical levels, the state weather bureau reported Sunday evening.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa) issued the update at 6 p.m., indicating gradual improvement in the dam's water status. The facility, which supplies water to portions of Metro Manila and surrounding areas, has been closely monitored during the rainy season.

While the drop below overflow level represents a positive trend, officials cautioned that the water level maintaining its position above the critical mark warrants continued vigilance. Dam operators have been managing water releases based on weather forecasts and precipitation data.

The dam's status remains a key concern for water security and flood risk management in Quezon City and downstream communities. Pagasa continues to monitor atmospheric conditions and water levels as the weather situation develops.
