Status Of Major Dams in Luzon
October 5, 2009
The PAGASA-DOST being the lead Agency in the Flood Forecasting and Warning System for Dam Operation (FFWSDO) informed all the concerned government agencies, local government units the status of the monitored reservoirs in Luzon as of 10:00 AM today.
The Pantabangan Dam continues to spill 150 cubic meters per second (cms), with 2 gates open and a total opening of 3.2 meters. Although the outflow is minimal compared to the carrying capacity of the upper Pampanga river, the municipalities/city in the province of Nueva Ecija that are likely to be affected by the release of Pantabangan dam are: Rizal, Bongabon, Gen. Natividad, Palayan City, Cabanatuan City, and Sta. Rosa.
The reservoir water level (RWL) is now at 220.15 meters above mean sea level (m. AMSL) and is 0.85 meters below the normal level of 221.0 m AMSL. Although light rains still prevail over the watershed, the Pantabangan dam spillways will remain open until the inflow into the reservoir will become stable.
Angat Dam has an elevation of 213.81m. AMSL and its spillway gates are closed since there is no major weather disturbance that threatens the watershed. For Ipo dam, located about 7 kilometers downstream of Angat dam, its present elevation is 100.44 meters (about 0.56 meters from its spilling level of 101 meters). The target areas of Angat/Ipo dams are the municipalities of Bulacan namely: Norzagaray, Angat , San Rafael, Bustos, Baliuag, Pulilan, Plaridel and Hagonoy.
As of 9:00AM today, the Magat dam spillways were closed since TY Pepeng is too far to affect the watershed of Magat. The RWL of Magat is at 190. 93 m. AMSL (about 2.07 meters below the normal high water level of 193.0 m. AMSL. With the passage of TY Pepeng, no major flooding was noted within the target area of Magat dam which include the municipalities of Ramon, San Mateo, Aurora, Cabatuan, Luna, Reina Mercedes, Burgos, Naguilian and Gamu in the province of Isabela.
The Agno river is regulated by three (3) reservoirs namely: Ambuklao and Binga in Benguet and San Roque dam in Pangasinan. During the passage of Typhoon Pepeng, the spillways of Ambuklao and Binga dams were operated due to the moderate to heavy rains in the upper reaches of the watershed resulting in the increase in the RWL of San Roque dam. At present, RWL of San Roque is at 283.99 m. AMSL which is 4.01 meters below the normal level of 288.0 m. AMSL. The light rainfall forecasts for the next 24 hours over the upper Agno river basins and the outflow from Binga dam of 469 cms (3 gates open and total of 3 meters opening) are not sufficient to fill the San Roque dam to its normal level within the next couple of days and therefore will not warrant the operation of its spillways. In the event that San Roque dam will open its spillways, the municipalities that are likely to be affected in Pangasinan are: San Manuel, San Nicolas, Tayug, Sta. Maria, Asingan, Villasis, Alcala, Bautista, Rosales and Bayambang.
All residents along the upper Pampanga river and upper Agno river are advised to take precautionary measures and stay tuned to warnings/advisories from PAGASA. The PAGASA will continue to provide update on the monitored reservoirs until such time that all spillway operations are terminated.

Angat has been gradually releasing water since Tuesday to stop it from reaching spilling level. Aside from providing 97 percent of the domestic water supply in Metro Manila, it also irrigates about 27,000 hectares of farmlands in Bulacan and facilitates flood control in the province.

Time Updated: |
6:00 AM |
Status of Angat Dam. Water level of reservoir. As you can see, the water level went above the spilling level last Sept 26-27.
As of October 1, 6:00 AM, Angat Dam reservoir water level is 212.57m. It is 0.57m above the Flood Season High Water Level! Does this mean they will open the dam again? Or are they going to wait until it reaches the level it reached last Sept 26 at the height of typhoon Ondoy, and open it up until it submerges Metro Manila AGAIN?!?
