CITY OF MALOLOS, Bulacan -- Rains brought by tropical depression Maymay have raised the water level of Angat Dam by almost half a meter yesterday while Bustos Dam discharges minimum volume of water .
Records from the Provincial Disaster Risk Reduction Management Office (PDRRMO) showed that the water elevation of Angat Dam as of 2:00 p.m. yesterday was at 157. 58 meter (M) compared to the previous day's 157.09M.
The water elavation is 49 centimeters or almost half a meter higher compared to Wednesday's record.
Yesterday's Angat Dam's water elevation is 2.42 meters below the 160-M critical level and 22.42 M below the dam's minimum operating level of 180 M and 54.42 meters below its rainy season normal high water level of 212 M.
The PDRRMO also reported that as of 11:00 am yesterday, the water elevation of Bustos Dam was recorded at 15.82 M or just 18 centimeters below its spilling level of 16.00 M and
has raised its Sluice Gate No. 3 by one meter that discharges 10 cubic meter per second of water to its downstream river system.
Angat Dam provides more than 90 percent of Metro Manila's domestic water needs, then for hydro power generation and lastly for irrigation supply to Bulacan and parts of Pampanga's ricelands.
Earlier, the Metropolitan Waterworks and Sewerage System (MWSS) reported that the indigenous peoples of Bulacan, Dumagat- Remontado, conducted their third "Rain Dance" on Tuesday (August 4) at the Angat Tailrace in Barangay San Lorenzo, Norzagaray, Bulacan.
It added that the ritual stands as a powerful reminder that we all have a part in safeguarding our environment
Meanwhile, Christian Manalo, National Irrigation Administration (NIA) acting Central Luzon director, clarrified that the rising water elevation of Bustos Dam is coming from the local flow of its upstream river system and not from Angat Dam.
He explained that Bustos Dam did not released its excess water to its main north and south irrigation canals because ricelands on its service are still saturated with rainwater thus the need to discharge its excess water to its downstream river system.
