NPC warns of potential dam discharge from San Roque Dam due to southwest monsoon

The National Power Corp. (NPC) warned about potential dam discharge from the San Roque Dam in Pangasinan, as water levels reached 273.08 meters above sea level on Tuesday.

By noon Wednesday, the water level had risen to 277.86 meters above sea level, prompting NPC to open a gate by 0.5 meters starting at 4 p.m., releasing approximately 65 cubic meters per second of water.

As of Friday afternoon, two gates were opened by a total of 4.5 meters, increasing the estimated discharge to around 880 cubic meters per second, with the dam's water level reaching 282.87 meters above sea level.

NPC continues to monitor weather conditions due to southwest monsoon activity affecting upland areas and remains in communication with local disaster risk reduction offices for potential preemptive evacuations of residents in low-lying areas along Agno River.

Teresa Serra, flood operation manager at NPC-San Roque Dam office, advised local disaster risk reduction offices in affected towns to take preparatory measures as significant rainfall could trigger further spill operations from the dam.
