The MWSS and Maynilad has begun its cloud seeding operations to create artificial rain that will replenish ground water supplies and potentially boost rainfall to avert the dwindling water levels at Angat, Ipo and La Mesa dams.


The 1st cloud seeding operations (CSO) was funded by the MWSS/Maynilad Water Services, in coordination with the Department of Agriculture – Bureau of Soils and Water Management (DA-BSWM), Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and Philippine Air Force (PAF). Said operation is part of the 26 sorties/flights committed to be funded by MWSS and Maynilad out of the 66 CSO sorties targeted to be deployed at Angat watershed this summer.


As of 12 March, Angat Dam has further dipped to 200.58 meters, or a -0.12 difference from 200.70 meters elevation level in 11 March 2020. Early cloud seeding is part of the MWSS and the Concessionaires’ summer mitigation program to prevent the water level in Angat from further receding aside from other pressure management, supply augmentation, and network improvement measures currently being implemented.

PAGASA has deployed its weather forecasters and installed a mobile weather radar including an all-weather station in Angat Dam to provide optimized cloud observation data in the Bulacan watershed area.
