In the Philippine Atmospheric, Geophysical, and Astronomical Services Administration's (PAGASA) monitoring as of 6 a.m. Monday, it showed that the level of Bulacan's Angat Dam has decreased to 212.86 meters. Its water level was at 213.30 meters last Sunday.

The dam's current water level remains a little above its 210.0-meter to 212.0-meter normal high water level but authorities have already stopped the release of excess water from its reservoir.

On Monday, Ipo Dam in Bulacan reduced its water discharges with only one spillway gate open at 0.15 meters. 

Its current water level is at 100.59 meters, or 0.31 meters short of its 101.1-meter normal high water level.

Ambuklao and Binga Dams in Benguet likewise lessened the volume of water discharges from their reservoirs but two spillway gates each remained open on Monday.

Both of the dams have seen water levels slightly down on Monday but are still near spilling levels.

Ambuklao Dam's water level was down from 751.69 meters to 751.51 meters, while Binga Dam's water level decreased from 574.40 meters to 574.31 meters.

Ambuklao Dam's normal high water level is 752.0 meters, while it is 575.0 meters for Binga Dam.

Magat Dam continued its discharges at a reduced rate with one spillway gate still open as of Monday. 

Its water level was slightly up from 192.15 meters to 192.28 meters, a little below its 193.0-meter normal high water level. 

In the PAGASA's flood bulletin on Monday, it noted a "continuous recession on water level" and "flooding no longer persists" in most areas that have been flooded, except in some areas near the Buntun Station of the lower Cagayan River.

Low-lying areas that are still likely affected by flooding are Peñablanca, Tuguegarao City, Enrile, Solana, Iguig, Amulung, Alcala, Baggao, Lasam, Gattaran, Lallo, Camalaniugan, and Aparri.
