Sinag to SRPC: Continue releasing water
By Virgilio Sar. Maganes
ROSALES- Abono Partylist Chair Rosendo O. So urged the management of San Roque Power Corporation (SRPC) that operates the San Roque Dam to continue the release of water until it reaches the 280 meters above sea level (masl), the spilling level of the dam.DAM. A spillway gate of the San Roque Dam in San Manuel town is opened at one meter last October 21. Some of the spillway gates which were also opened last October 20 were eventually closed as inflow water started to decrease.CESAR RAMIREZ
So, also the president of the Samahang Industriya ng Agrikultura (Sinag) observed that three days after Super typhoon Lawin exited Northern Luzon, the dam’s gates were already closed when water level was 285.98 masl.
” In the next five days. there will be no rain to add water to the dam, but still they have to lower the dam’s water level at 280 masl, which was the agreed protocol level when water should be released. The water level of the dam is still about six meters above the agreed spilling level,” So said.
During the height of Super typhoon Lawin last October 19, residents of the municipalities along the Agno River became restless especially when they learned that Ambuklao and Binga Dams were releasing water which is caught by the San Roque Dam, but still there was no information as to when the dam’s gates will be opened.
It will be recalled that at 10:00 in the morning of October 20, when the dam reached 281.72, SRPC opened half meter of one gate to release 350 cubic meters per second (cms).
At 3:00 in the afternoon of the same day, inflow of water from the Binga and Ambuklao Dams reached 3,850 cms, much higher than the dam’s outflow of 980 cmps.
The dam was already spilling at a level of 285 masl when SRPC decided to open three more gates.
Three gates were open by one meter and one gate was open at two meters.
The release of the water from the dam has swelled Agno River, which was monitored by staff of Abono Partylist, including So.
Recall that in October 2009 at the height of Typhoon Pepeng, SRPC was remiss of its duty to open the dam’s gates until the dam reached the critical level. Thus the abrupt opening of the dam’s six gates with an outflow of more than 6,000 cms flowed to the Agno River that can accommodate only 3,000 cmps.
The said situation has caused flooding of municipalities along the Agno River that destroyed millions worth of properties, crops and animals.
“We don’t want to experience again the 2009 flooding that’s why we have to be alert on the releases of dam’s water along the Agno River,” So said.
