The recent flooding in Cagayan has already subsided with the continuous recession of lower Cagayan River’s water level on Tuesday, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

A final flood bulletin was issued by PAGASA on Tuesday as “flooding no longer persists,” particularly in areas near the lower Cagayan River and its tributaries Pinacanauan de Tuguegarao, Chico, Pared, and Dummun rivers.

“With this development and unless significant rains will occur in the immediate future to affect the (Cagayan River) basin, this is the final bulletin,” PAGASA said.

Local officials earlier attributed the excessive rainfall over the watershed due to typhoon Ulysses and other previous weather systems and the release of water from Magat Dam in Isabela that caused the rivers to overflow.

Magat River, along with 19 other tributaries, flow into the Cagayan River and that prompted widespread flooding in Cagayan. 

Based on the PAGASA’s monitoring as of Tuesday noon, Magat Dam was still discharging excess water with one gate open at 2 meters high. 

Magat Dam’s water level was slightly down from 192.28 meters on Monday to 192.22 meters on Tuesday, but still near its 193.0-meter normal high water level.

PAGASA reported that Ipo Dam in Bulacan has stopped releasing water on Tuesday, but Ambuklao and Binga Dams in Benguet were still discharging excess water.

Ambuklao and Binga Dams each have two spillway gates open as they remain close to their spilling levels. Their normal high water levels are 752.0 meters and 575.0 meters, respectively.

Ambuklao Dam’s current level was at 751.44 meters, down from 751.51 meters, while Binga Dam’s current level was at 574.53 meters, slightly higher than the 574.31 meters, previously.
