Napocor terminates water spilling operations at San Roque dam
After containing huge water inflows from five successive typhoons and rains from enhanced southwest monsoons
The National Power Corporation (Napocor) on Thursday announces the closing of all spillway gates of San Roque dam after it reached the target elevation of below 275 meters above sea level (masl).
As of 8 AM today, the dam’s elevation is at 274.62 masl. Its normal high-water elevation (NHWL) is 280 masl.
Napocor’s Dams Management Department (DMD) said that the target elevation will give leeway for future water inflow especially during another tropical depression.
The corporation also emphasized the flood mitigating function of dams which helped hold and control huge amount rainfall from going straight to the Agno river and nearby towns.
Water discharge in brief
It can be recalled that the San Roque dam started its spilling operations in the morning of 12 August 2018 when its elevation breached the NHWL of 280 masl. Water elevation peaked at 287.19 masl on August 14, 2018 due to the continuous large inflows from heavy rain caused by Tropical Storm Karding and the enhanced southwest monsoon (habagat). Spilling of water from Ambuklao and Binga dams which cascades to San Roque dam also contributed to the increased elevation.
For the next ten days, spilling operations continued to avoid overflow and to allow sustained decrease in reservoir water elevation until it reaches the target elevation of 275 masl.
However, the declining elevation stalled at 276.28 masl on 24 August due to the moderate rainfall brought about by Tropical Depression Luis which also increased the water discharge of upstream dams Ambuklao and Binga.
San Roque dam’s elevation peaked at 281.00 masl in the morning of 27 August, thus the continued water spilling operations. It finally attained target elevation on 30 August at 8:00 AM.
Napocor said that few weeks prior to Typhoon Karding, the Ambuklao, Binga and San Roque dams already contained massive amount of rainfall and water inflow brought about by Tropical Storms Henry, Inday and Josie in North and Central Luzon.
Dams for flood control
Napocor said that apart from power generation, dams likewise have flood control and mitigation functions, preventing loss of life and property caused by massive flooding. Dams impound floodwaters and release them under control to river or store them for other uses like irrigation.
“We continually monitor the inflow of water to the reservoir and the PAGASA reports so as to be on guard on the dam’s situation,” said Napocor’s DMD Chief Conrado Sison.
Napocor assures the public that the corporation, along with the San Roque Power Corporation who operates the San Roque hydropower plant and SN Aboitiz Power who operates Ambuklao and Binga hydropower plants, strictly complies with the coordination protocol on dam operations as contained in its Dam Safety Program.

Napocor prepares San Roque dam for upcoming rains, continues spilling operations
The National Power Corporation (Napocor) on Friday announces that San Roque Dam in Pangasinan continues to discharge water with a 3.5-meter gate opening and outflow of 548 cubic meter per second (cms).
Napocor said that the 548 cms water outflow has no significant impact to the Agno river.
As of 10am today, the dam’s water elevation is at 276.33 meters above sea level (masl).
“We are targeting to reach an elevation of 275 masl within this week. However, due to the moderate rainfall brought about by Tropical Depression Luis, we may have to extend the water spilling operations of San Roque dam until Sunday or Monday,” said Napocor spokesperson Odette Rivero.
Rivero said that water spilling continues in preparation for huge water inflows to the Ambuklao, Binga and San Roque dams due to possible heavy rains or typhoons in the future.

San Roque dam elevation still above the normal high water level, spilling operations continue - Napocor
The National Power Corporation (Napocor) on Wednesday continues the water spilling operations at San Roque dam in Pangasinan with water outflow of 785 cubic meters per second (cms) to further bring the water level into its normal high-water level of 280 meters above sea level (masl).
“Current level of dam as of 10am today is 285.61 masl and we are closely monitoring the inflow and outflow of water in the dam with the San Roque Power Corporation. We also maintain coordination with the Pangasinan Provincial Disaster Risk Reduction and Management Office for timely advisories for the community,” said Engr. Conrado Sison, head of Napocor’s Dams Management Department.
Napocor said that there had been significant decrease in water elevation from 287.18 masl yesterday to today’s elevation, due to decreased inflow of water from 1342 cms to 890 cms. Thus gate openings were also reduced from 6.5 meters (five gates) to 4.5 meters (three gates).
Although there is an improving weather condition in the area, the dam elevation is still high which calls for continuous water discharge from its spillway.
Municipalities along the dam/flood warning zones include San Manuel, San Nicolas, Tayug, Sta. Maria, Villasis, Asingan, Rosales, Alcala, Bayambang and Bautista.
Napocor is likewise closely monitoring the reservoir and the amount of rainfall over Angat watershed in Bulacan. Angat Dam, which has a normal high-water elevation of 212 masl, has a current level of 205.88 masl. END
