The rains brought by typhoon Karding (international name: Noru) helped raise the water level at Angat Dam, which increased by 6.81 meters, based on the monitoring of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday, Sept. 26.

In its 6 a.m. dam water level update, PAGASA reported that the water level at Angat Dam has climbed to 183.97 meters, which means that it is now higher than its minimum operating level or critical level of 180 meters.

Its water level was at 177.16 meters on Sunday, Sept. 25.

Moreover, Angat Dam’s current level is just 1.28 meters below its rule curve elevation of 185.49 meters.

PAGASA defines rule curve elevation as the minimum reservoir elevation needed to be maintained by dam operators to ensure availability of water for irrigation, power generation, and domestic supply.

However, Angat Dam’s water level is still way below its 212-meter normal high water level during the rainy season.

The dam located in Bulacan supplies 98 percent of Metro Manila’s potable water requirements.
