NIA Inaugurates 7 Irrigation Projects in Sanchez Mira, Cagayan

October 11, 2021, 1:26 PM
 

NIA Region II – The National Irrigation Administration (NIA), presided by Senior Deputy Administrator Abraham B. Bagasin, inaugurated and turned over seven (7) irrigation projects worth P93 million in the Municipality of Sanchez Mira, Cagayan on October 1-2, 2021. These projects have a total service area of 475.61 hectares, benefitting 393 farmers and their families.

On October 1, 2021, NIA inaugurated the P10-million Labbac Small Irrigation Project (Labbac SIP) located in Barangay Namuac, Sanchez Mira, Cagayan. The project is part of Namilagan Communal Irrigation System (Namilagan CIS) and has a Firmed-Up Service Area (FUSA) of 122.79 hectares with 78 farmer beneficiaries. Like other CIS in Sanchez Mira, Cagayan, the system was originally a Private Zanjera, local term of farmers who organized themselves to operate and maintain a privately constructed irrigation system.

Cristobal, all CIS Presidents (NIA-assisted) of Sanchez Mira, Namuac Barangay Officials headed by Brgy. Captain Fernando A. Guiang, CBIMO Head Office employees led by Mr. Victorio F. Urbina, Engr. Minda A. Battung of East Apayao Abulug Irrigation System, and representatives from the FBS Construction attended the event.

During the second day, NIA conducted the Mass Turnover Ceremony of six (6) other communal irrigation systems to the Irrigators Associations of Sanchez Mira. These include the 1) P23-million Cusiten CIS with service area of 186.20 hectares and 59 farmer-beneficiaries, 2) P5-million Capanickian CIS with service area of 53.30 hectares and 67 farmer-beneficiaries, 3) P5-million Namilagan CIS with service area of 122.79 hectares and 78 farmer-beneficiaries, 4) P15-million Nagkarsuan CIS with a service area of 72 hectares and 64 farmer-beneficiaries, 5) P5-million Pangyan Small Water Impounding System (Pangyan SWIS) with service area of 41.32 hectares and 47 farmer-beneficiaries, and 6) P30-million Pangyan and Battuguit CIS under the Pangyan SWIS. Local Government Officials and Irrigators Associations in Sanchez Mira, Cagayan attended the turnover ceremony.

CONTINGENCY PLAN FOR THE MAGAT DAM IN PLACE

September 13, 2021, 10:02 AM
 

NIA Central Office – The National Irrigation Administration (NIA) ensures that it has an existing contingency plan for the Magat Dam located in Municipality of Ramon, Isabela.

On September 01, 2021, a Regional Committee on Dam Safety (RCODS) meeting was held virtually attended by the Cagayan Valley Disaster Risk Reduction and Management Council, Department of Agriculture (DA) Region II, NIA-Region II, NIA-Magat River Integrated Irrigation System (NIA-MARIIS) Philippine Atmospheric Geophysical and Astronomical Administration (PAGASA), Department of Science and Technology (DOST) Region II, Department of Environment and Natural Resources (DENR) Region II, National Housing Authority (NHA) Region II, Isabela State University, and concerned Local Government Units (LGUs). Revised Protocol on Dam Discharge and Flood Warning Operation for Magat Dam was discussed by Acting Head Edwin J. Viernes of the Flood and Forecasting and Instrumentation Section of NIA-MARIIS and a Technical Working Group under the RCODS was directed to be created to review and finalize the project proposal on the Ensemble Technique for Rainfall Runoff Forecasting.

Contrary to the reported that the Office of the Civil Defense (OCD) Region II and the Regional Committee on Dam Safety (RCODS) approved the crafting of the contingency plan proposed by the Provincial Disaster Risk Reduction Management Office (PDRRMO) in case of a possible Magat Dam break during the said virtual conference, NIA-MARIIS assures that it has existing emergency measures for weather phenomena or disturbances, natural disasters, and even manmade disasters that may result to dam breakage.

In fact, the Operation, Maintenance and Safety Manual for the Magat Dam is in place updated since 2007. The first Manual on Magat Operation and Dam Safety was published in 1982 a year before the 1983 official completion of the Magat River Multipurpose Project. To further improve the operation procedures for the Magat Dam especially during occurrences of floods, the PAGASA in cooperation with the NIA and the National Power Corporation (NPC) came out with a Flood Operation Rule for the Magat Dam in April 1992. Ever since, the Magat Dam was operated based on these two Operation Manuals. In 2007, the NIA-MARIIS formed a Committee to review and update the present Dam Operation Manuals. With the support of PAGASA and the assistance and corroboration provided by the SN Aboitiz Power Inc. (SNAP), the Committee came out with the second revision of the Dam Operation, Maintenance and Safety Manual.

Furthermore, instruments and equipment are embedded since the making of the Magat Dam such as Piezometers monitoring pressure beneath or within the embankment pore water pressure, Strong Motion/Accelerograph tracking structure behavior if earthquake occurs and internal stresses, Surface Measuring Points (SMP) surveyed for possible settlement and deformation, and Weirs for checking seepages in the dam embankment. Aside from these, with modernization and technological advancements, new instruments are in place such as Dam Deformation Monitoring System serving as an online monitoring producing data points every 30 minutes for the covered structure. Thus, any abnormalities on the structure will be tracked right away and be acted upon even before a dam break.

According to Acting Manager Carlo C. Ablan of the MARIIS Dam and Reservoir Division, with the Magat Dam’s 39 years in operation, there is still no major deformity or damage on the Magat Dam. 

Recently, during the onslaught of Typhoon Ulysses (Vamco) in Luzon, Cagayan Valley Region was not spared with its widespread flooding. The Magat Dam Protocol on Dam Discharge and Flood Warning Operation was revised after the creation of the Dam Crisis Management Task Force dedicated to review the existing protocols and address concerns on dam management crisis following the flooding incident. This move to revise the Magat Dam Protocol on Dam Discharge and Flood Warning Operation is a way to enhance the Manual in accordance with the changing times with the weather changes affecting dam operation procedures, other partner Agencies’ plans, and the increased awareness and participation of the Local Government Units (LGUs), private organizations and other stakeholders on the impact of the Magat Dam.

The MARIIS Dam and Reservoir Division is strengthening the construction of sediment catchment structures upstream of Magat Reservoir to inject short term solutions for the sedimentation deposition in the reservoir. 27 sediment catchment structures are already in place for sediments not to go down in the reservoir. Aside from that, reforestation in the Magat Watershed is being done since 2014. These are alternative interventions for mitigation prior to a conduct of a feasibility study of the proposed dredging activities at the Magat Dam Reservoir to ensure the structural stability of the Magat Dam and increase the reservoir capacity for irrigation, power generation and flood control.

NIA Administrator Ricardo R. Visaya assures that as the Agency commits to its mandate to manage and maintain irrigation systems, is always ready to support and cooperate with other government agencies in disaster risk mitigation and crisis management.
