Despite rains, Angat Dam’s water elevation still below minimum operating level


CITY OF MALOLOS, Bulacan — The water elevation in Angat Dam is still below its minimum operating level despite the moderate to occasional heavy rains felt in its watershed areas.

Records from the Provincial Government of Bulacan showed that the water elevation in Angat Dam as of 8 a.m. on Tuesday (Sept. 15) was at 176.81 meter which is 3.19 meters below its 180-meter minimum operating level and 35.39 meters below its ideal end-of-the-year 212 meter level.

The onset of the rainy season did not stop the water elevation of the dam from sliding down.
On June 30 this year, the water elevation of Angat Dam was recorded at 188.52 meter, the following month on July 31 it slide down a bit lower at 182.45 meter, the following month on August 31 it fell by  1.89 meters at 180.59 meter and by Tuesday morning it fell down to 176.81 meter.

Early this month, Sevillo David Jr., executive director of the National water Resources Board said.the water allocation for Metro Manila domestic needs and irrigation supply to Bulacan and some parts of Pampanga farmlands are maintained at 46 cubic meter per second (cms) and 30 cms respectively for the month of September.

It can be recalled that the NWRB increased the water allocation for Mero Manila residents from 46 cubic meters per second (CMS) to 48 CMS on May 14 this year to sustain the steady supply of water in performing preventive measures against the Coronavirus Disease 2019 (COVID-19) such as frequent handwashing and other hygiene, cleaning and disinfection activities.

David said the NWRB reverted to the regular water allocation for Metro Manila water needs to 46 cms considering  the current level of Angat Dam and added ” We are also expecting some local inflows to the MWSS reservoir during this rainy season to complement raw water releases from Angat”

The “NWRB in collaboration with other government agencies such as MWSS, NIA, Pagasa [Philippine Atmospheric, Geophysical, and Astronomical Services Administration], NPC [National Power Corporation] are closely monitoring the situation in Angat and impacts to water supply for Metro Manila and  irrigation,” David said.

He added that they are guided by the near normal to above normal rainfall projections of Pagasa for the rest of the year and probable occurence of a La Nina Episode by the last quarter of the year. (RONDA BALITA Online)
