San Roque dam, flood control projects credited for absence of severe floods in Pangasinan since 2004
By Danny O Sagun
Dagupan City (02 October) -- Flood control projects on major river tributaries in Pangasinan have prevented severe flooding in this city and nearby towns, the head of the Agno River Flood Control Office said in a media forum.
Engineer Fidel Ginez told the special Engkwentro forum at the Lenox Hotel Friday that Dagupan and neighboring Mangaldan, Sta. Barbara and other towns have seen no worst floods since 2004 because of the flood control projects. It is only in Calasiao where flooding is still a problem particularly in barangays San Vicente, Banaoang and nearby areas, he noted.
He said that the flood control project in Sison town diverted the flow of waters from the Mt. Ambugao area direct to Bued River and no longer pass thru Aloragat and Angalacan rivers which contribute to the flooding in Dagupan and Mangaldan. "Kung may baha man, dahil na sa lakas ng ulan at high tide," he said.
Ginez, who has been with the flood control office since 1972, also credited the San Roque multi-purpose dam for the significant decrease in flood incidents in Pangasinan. As of Friday, the water elevation of the dam was at 277.96 meters above sea level. Depending on weather situation, the dam may release waters when the level reaches 280 meters.
It was only in 2004 that the dam was forced to release waters.
"Kung may releases man ngayon ay dahil sa power generation, pero minimal lang," he said. In 2013, when the re-regulating pond of the National Irrigation Administration would have been completed, waters used in power generation will then be stored in that pond for irrigation purposes.
The San Roque dam, said to be the biggest in South East Asia, can adequately contain water releases from the upstream Ambuklao and Binga dams as it has been observed for the last five years, he pointed out.
Asked if the province would see floods similar to what hit Metro Manila last weekend, he said he agreed with the observation of Gov. Amado T. Espino, Jr. that the situation here is different because of the presence of the Agno River and many other river tributaries that serve as catchment basins.
Meanwhile, Ginez asked local government authorities to help check pilferage of cyclone or gabion wires, which, he said, results in the weakening of dikes. "Maraming bahay na may bakod na gabion pero wala kaming police power," he said. The gabion wire does not corrode even after several years.
He said that pilferages were observed in Sison, Urbiztondo, Bayambang, San Carlos City and other areas. "Susulatan ko na lang ang mga mayors," he said. (PIA Pangasinan) [top]
