Luzon's major dams have reported noticeable decreases in water levels as of May 16, 2026, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
The latest data reveals that six out of nine monitored dams experienced a drop in water elevation, coinciding with the country's rising temperatures and warnings about a possible El Niño phenomenon.
Key Water Level Changes
Despite a slight increase in levels at Ipo, Ambuklao, and Magat Dams, the overall trend suggests increasing concerns about water availability for Metro Manila and surrounding areas. Angat Dam, which is critical for the metropolitan area's water supply, remains significantly below its operational threshold.
The National Water Resources Board (NWRB) is considering cloud-seeding measures to address the declining water situation, particularly in the Angat Watershed. This move reflects a growing urgency as the summer months intensify the demand for water.
The current situation highlights the ongoing challenges faced by water management authorities in the Philippines, particularly as climate variability continues to impact water resources.
