Angat Dam Water Level Falls Below Critical Mark, Raising Risk of Metro Manila Water Interruptions

 

The continued decline in Angat Dam's water level has renewed concerns over the reliability of water supply across Metro Manila, prompting authorities to closely monitor both reservoir conditions and upcoming weather developments.

Latest measurements placed the dam's elevation at 158.75 meters, placing it below the critical threshold of 160 meters. Crossing below this benchmark does not automatically trigger widespread disruptions, but it significantly narrows the buffer available to meet the water demands of millions of residents.

The National Water Resources Board is currently assessing the situation while evaluating weather forecasts that could influence the reservoir's recovery. Executive Director Sevillo David Jr. said the agency is reviewing existing conditions alongside expected rainfall before determining whether additional measures may become necessary.

The country's weather bureau has also reported that Super Typhoon Bavi could enter the Philippine Area of Responsibility on July 8. Any substantial rainfall associated with the weather system may help replenish Angat Dam, although authorities remain cautious because prolonged extreme heat has accelerated water loss and heightened concerns over a potential supply shortage.

Angat Dam serves as the primary water source for Metro Manila, making its elevation a closely watched indicator. When reservoir levels decline beyond safe operating margins, water providers may have limited flexibility to sustain normal distribution. The situation is comparable to a household water tank that is being drained faster than it can be refilled. As the reserve shrinks, every day without sufficient replenishment increases the likelihood of supply restrictions.

The current conditions also revive memories of the 2019 water crisis. During that period, Angat Dam's water level dropped below the critical mark, forcing the implementation of rotational water service interruptions across Metro Manila. Irrigation deliveries to farms in Bulacan and parts of Pampanga were likewise suspended to conserve the remaining water supply.

While no new water interruption schedule has been announced, authorities continue to monitor reservoir levels and weather conditions to determine whether preventive measures will be required in the coming days.
