NIA denies release of water from Magat dam caused the Cagayan-Isabela deluge
National Irrigation Administration (NIA) chief Ricardo Visaya stated that the opening of Magat Dam's gates was not the primary cause of the severe flooding in Cagayan and Isabela.
Visaya presented data during a House joint panel inquiry showing that water inflow into the dam from November 9 to 14 was 7,128 cubic meters per second, while the outflow was only 6,706 cubic meters per second.
He contrasted this with the water level at Buntun Bridge, which measures the Cagayan River's water level, reaching 13.2 meters during the typhoon.
Visaya concluded from this comparison that the water released from Magat Dam did not significantly contribute to the widespread flooding in the affected provinces.
