MANILA – The National Power Corporation (Napocor) has urged residents of Metro Manila and Luzon to use water wisely as water supply from dams drops amid the summer season.
Napocor president Gladys Cruz Sta. Rita on Wednesday the water level in Angat Dam is now at 190.47 meters, which is still above the critical level of 180 meters.
However, the water level was 210 meters in end-December 2013, or a 20-meter drop.
Sta. Rita said since super typhoon Yolanda, no more rain poured at the watershed, which caused the water level to fall.
Once the water level reaches 180 meters, allocations for irrigation will be cut and the portion for water concessionaires will also be reduced.
In January, the national water resources board reduced the allocation for household supplies to 42 cubic meters per second (cm/s) from 46 cm/s.
With the rate of reduction of 20 centimeters every day, the water level in Angat is expected to reach critical level by mid-May.
Most of the dams in Luzon monitored by Napocor are still normal but others are nearing critical level:
Dams Current level Minimum operating level
Ambuklao 740.19 meters 740 m
Binga 567.78 meters 565 m
San Roque 245.95 meters 225 m
For Mindanao, the Agus-Pulangi Hydro Electric Facility is also producing less power and less water for irrigation due to the lower water level.
Lake Lanao is at 700 meters while the critical level is 698 meters. Pulangi 4 Dam is at 282.2-meter level while the critical level is at 282 meters.
