WATER IN San Roque Dam is already way above the forecast end-November 2020 elevation and is unlikely to stop rising soon.
The dam's 6 a.m. water level on Monday was at 272.33 meters, showed Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) data.
Such water level is almost 29 meters higher than the 243.76 meters end-November water elevation forecast by PAGASA for San Roque a month ago.
"That dam continues receiving considerable water," said PAGASA hydrologist Max Peralta, explaining the rise in water level in the said facility.
Such rise may not yet stop soon as Binga Dam is still releasing water to San Roque, he noted.
He also said Ambuklao Dam resumed its spilling operation on Monday, enabling this facility to again discharge water into Binga.
There's some rainfall in Benguet province where Ambuklao and Binga are so these dams continue getting water, he said further.
San Roque, located in the province of Pangasinan, catches water from Binga which in turn receives water from Ambuklao.
These facilities comprise the trio of cascading dams supporting irrigation and power generation in Luzon.
The 6 a.m. water levels of Angat and Pantabangan dams on Monday were also higher than the forecast end-November 2020 elevations by 13.95 meters and 0.18 meters, respectively.
Magat Dam's 6 a.m. water on Monday is still below the forecast full-capacity elevation of such facility by this month's end, Peralta noted.
PAGASA data showed as of 6 a.m. Monday, a gate of Binga Dam was open at a height of 0.50 meters to accommodate spilling operations there.
That enabled Binga to release more water then compared to 24 hours earlier when the opening's height was 0.30 meters.
Ambuklao Dam on Monday opened its gate at a height of 0.30 meters to spill water.
San Roque, Binga, and Ambuklao dams experienced a water deficit due to a rainfall shortage earlier this year.
However, the successive onslaught of tropical cyclones since last month enabled these dams to begin recovering. (By Catherine Teves)
