DAGUPAN CITY — The Agno Flood Forecasting and Warning Center (AFFWC) said it has no plan to recommend the opening of any gate of the San Roque dam even if the elevation at the dam’s reservoir already reached 278.89 meters above sea level (masl) as of 3:00 p.m. Thursday.
The critical level of water of the San Roque dam, located downstream of the Agno River, is 280 msl.
Virgilio Garcia, senior hydrologist of the AFFWC, said San Roque said no spilling operations will be made as San Roque just maximized its power generation.
Rather than opening a flood gate to decrease the volume of water at its reservoir, San Roque just made full use of the big volume of water available.
The increased volume of water at San Roque, he said, is attributed to the opening of one gate of Ambuklao Dam in Bokod, Benguet by .06 meter, and one gate of Binga dam in Itogon, Benguet by .05 meter.
Released water from the two dams located in the upper stream of the Agno river flows down the bigger San Roque dam.
Slight to moderate rains were felt in Pangasinan beginning Tuesday, December 15 but were not enough to bring floods even in the low-lying areas of the province, including in Dagupan.
Rains have ceased all over the province as of morning of December 17.
However, Pangasinan was still placed under Typhoon Signal No. 1 on December 17 which forced authorities to declare automatic suspension of classes in the pre-school level. PNA
