Tisoy’ improves water level at Angat Dam reservoir

MANILA, Philippines — After months of receding elevation, the water level at the Angat watershed in Bulacan improved significantly after the onslaught of Typhoon “Tisoy” (international name: Kammuri).

The Philippine Atmospheric, Geophysical and Astronomical Services Administration  said the reservoir’s water level increased to 193.47 meters above sea level (masl) on Tuesday morning.

It was up by 4.5 m from the previous day, following the onslaught of Tisoy, the agency added.

But it’s still far from the normal high water level at 210 masl, although it was better than the operating level at 180 masl.

Angat supplies most of the water needs of Metro Manila and nearby provinces.

Ipo Dam, too

Water level in Ipo Dam, also in Bulacan province, similarly increased to 101.2 masl on Tuesday, up by 1.05 m from the past day.

Elevations in Ambuklao Dam in Benguet province and La Mesa Dam in Quezon City also rose by less than a meter with levels recorded at 741.72 masl and 77.55 masl, respectively, compared to 741.57 masl and 77.42 masl the previous day.

Tisoy has weakened to a severe tropical storm and is expected to leave Philippine territory on Wednesday or Thursday.
