Binga Dam opens 3 spillway gates

DAGUPAN CITY — The National Power Corporation (Napocor) has opened three gates of Binga Dam in Itogon, Benguet by 1.3 meters as the level of water at its reservoir is now about to reach its critical or spilling level.

Napocor’s Flood Forecasting and Warning System (FFWS) commenced the water discharge operation at 6:00 p.m. of August 15 by initially opening spillway gate No. 3. In a few hours it was increased to three gates, noting that monsoon rains still continue in the upstream of the Agno River.

Binga Dam is one of three hydro-electric dams along the Agno River. The other two are the Ambuklao Dam in Bokod, Benguet and San Roque Dam in San Manuel, Pangasinan.

As of 8:00 a.m. today, the reservoir of Binga Dam was measured at 578.32 meters above sea level (masl), just 1.48 meters before it reaches the dam’s spilling level of 575 masl.

Ambuklao Dam, just above Binga, is at 746.89 masl or just 3.32 meters more before it reaches 752 masl.

The San Roque Dam, below Binga, was at 235.68 masl, yet too far away from reaching its spilling level of 280 masl.

The San Roque Dam is the largest of the three hydro-electric dams built along the Agno River. It is where all the water discharges from the Binga dam are being impounded.

It may take weeks of continuous rains before the reservoir of the San Roque Dam is filled up and begin discharging water downstream of the Agno River in Pangasinan. PNA/
