A day before Dayondon started scaling Vinson Massif, a 4892-meters above sea level (masl
) mountain in Antartica to complete the seven summits, Villegas said she was constantly hoping for a good weather.
Engineer Conrado Sison, head of NPC dams management department, noted that the current level of the dam as of 10am on Wednesday (August 15), was at 285.61 masl
, prompting the state-run firm then to continue monitoring "the inflow and outflow of water in the dam," along with San Roque Power Corporation.
San Roque Dam's water level has significantly increased from 280.62 masl
on Sunday to 284.58 on Monday, breaching its spilling level of 280 masl
He said the watershed needed about 370 millimeters of rainfall during a single occasion to raise it to the normal operating level of 180 masl
Rains brought by Typhoon Lando over the Angat watershed on Sunday increased the Angat Dam's water elevation by almost 4 meters--from 194.60 meters above sea level (MASL
) as of 6 a.m.
On Monday (July 1) it was 159.91 meters above sea level (masl
) compared to 159.04 masl
as of 2 p.m.
Angat Dam, which supplies 97 percent of Metro Manila's domestic water needs, is close to breaching its 180-meter above sea level (masl
) minimum operating level due to lack of rain over the Bulacan watershed.
After three days of intermittent rain, the reservoir's water level rose to 159.04 meters above sea level (masl
) early on Sunday (June 30).
