MANILA, June 28 The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said that three dams in Luzon are nearing their spilling level.
Water levels at Ipo Dam, La Mesa Dam and Ambuklao Dam are 100.46, 79.87 and 751.55 meters, respectively, according to PAGASA.
This means, based on analysis, Ipo Dam which has a normal high water spilling level of 100.87 meters is just 0.41 meters from its spilling level.
Engineer Heraclio M. Borja Jr., hydrologist and PAGASA assistant weather services chief, said: Actually Ipo Dams water level has already gone down from its level yesterday, Monday, June 27, which was 100.94 or 0.07 meters over its spilling level.
La Mesa Dam which has overflowed last Saturday, June 25, has receded Tuesday, June 28, to 79.87 meters from its Mondays level of 80.04 or 0.28 meters from 0.11 meters from its normal spilling level of 80.15 m., Borja said.
Ambuklao Dam, which situated in the Cordillera Autonomous Region (CAR) in Northern Luzon, which was forecast to experience effects of the Southwest Monsoon, was just 0.45 m. from its spilling level of 752.00 m., up from 751.27 m. or 0.73 m. deviation.
Caliraya Dam in Cavinti, Laguna, the fourth dam which may reach its spilling level, attained a 286.42-meter level lately with a deviation of 1.58 m. from its normal spilling level of 288 meters.
Borja said the other dams, particularly Angat Dam, Metro Manilas hydro-electric source, had still six meters or more from their respective spilling level.
However, Angat Dam has risen its level to 203.39 meters from 202.89 meters (Mondays level), or a deviation of 6.61 meters from 7.11 meters. (PNA) DCT/RMA/MAGI
