MANILA - The water level at La Mesa Dam, the source of most of Metro Manila's water for households, has fallen to its lowest in 5 years, state weather burea PAGASA said Thursday.
The dam's reservoir water level was at 72.68 meters as of 6 a.m., said PAGASA hydrologist Gine Nievares.
"Normal po siyang (water level) bumababa talaga 'pag sa buwan ng May... Pero ito po iyung pinakamababang lebel for the past 5 years," she told radio DZMM.
(It is normal for the water level to drop during the month of May. But this is the lowest level for the past 5 years.)
The plunge in La Mesa's water level was also the most abrupt in years, added Nievares.
"Sa record po namin, ito po ang masasabi kong pinakamabilis na pagbaba. Wala pa po siyang kaparehong taon," she said.
(Based on our record, I can say that this has been the fastest drop. It has no match in previous years.)
Concessionaires Manila Water and Maynilad share the water supply from La Mesa.
If the dam's water level drops to 69 meters, the East La Mesa Treatment Plant may shut down, which may affect water supply in Marikina, San Mateo, Pasig, Taguig and Rodriguez, Rizal, Manila Water has warned.
Maynilad, meanwhile, has been reducing water pressure in some areas in Quezon City and Camanava during the wee hours.
The National Water Resources Board is open to increasing the inflow of water from Angat Dam to augment the supply in La Mesa, executive director Dr. Sevillo David said a separate DZMM interview.
