QUEZON City – THE La Mesa dam has been placed under red alert status for possible “overflow” due to heavy rains brought by Super Typhoon Rolly, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa) Hydrology department said.
“There is a possibility of overflowing at La Mesa Dam. We are on red alert due to the passing of Rolly over our region” Hydrologist Richard Orendain said in an online press conference of Pagasa.
Orendain also stressed that there is also a possibility that the Ipo Dam in Norzagaray in Bulacan will be releasing water as it is nearly at its “spilling level”.
“There could be a possible release of water from Ipo Dam because it’s a small dam, its spilling level is 101.5 meters and the difference from spilling level is only about .5 meters so it will be filled by water because of the typhoon”. Orendain said.
Meanwhile, Orendain also warned of a possible water level increase of about 3 meters to 5 meters at the Angat Dam in Norzagaray, Bulacan.
However, he assured that Angat Dam will not reach its spilling point.
The hydrologist also warned of a possible increase of about 2 meters to 4 meters in the water level of the Pantabangan Dam in Pantabangan, Nueva Ecija.
In San Roque Dam, located at San Manuel, Pangasinan, the water level could increase by about 2 meters to 4 meters.
