The Philippines Department of Environment and Natural Resources (DENR) has been busy lately working on a massive dredging project in the Cagayan River.
According to DENR Secretary, Roy A. Cimatu , the government is hoping to complete the dredging of a “mega” island sandbar along the Cagayan River by early next year.
In a news release on Monday, Cimatu said that so far 81,807 cubic meters or 8.43 percent of the targeted 970,962 cubic meters of sandbar has been dredged since the operations in Barangay Dummun, Gattaran town, Cagayan province started in June.
“With its sheer size measuring 134.7 hectares, it is practically an island which is why this sandbar is a priority of the task force like the Magapit Narrows in (barangay) Lallo, Bangag (town) to widen the Cagayan River,” Cimatu said.
He also added that the Department of Public Works and Highways (DPWH) and the Armed Forces of the Philippines have expressed commitment to deploy additional equipment and workforce to complement the dredging operations.
Cimatu continued by saying that the dredged materials are being transferred to the eroded portion of Cagayan riverbanks in Barangay Dummun to restore the ideal alignment and speed up the water flow toward the river mouth in Aparri.
As reported by DENR-Region 2 Executive Director Gwendolyn Bambalan , the Cagayan River did not overflow during the passage of severe tropical storm “Maring” (Kompasu) in October.
In a report to Cimatu dated October 14, Bambalan said that only localized floods were reported in Cagayan as a result of the overflowing of lakes and rivers that drain into the Cagayan River. “Despite the massive flooding in different locations, the Cagayan River did not overflow. It did not reach its maximum capacity,” Bambalan noted.
“In Santa Teresita, Cagayan, a flash flood was reported due to the overflow of Mission, Bulasing and Luga rivers, Pacac creek and irrigation canals. Flood height reached to 1 to 2 meters at Barangay Simpatuyo, while the flooding in other municipalities were localized flooding only affecting agricultural lands,” said Bambalan.
Phase 1 of Cagayan River dredging activities, which focused on the constricted section of the river, called the “Magapit Narrows,” started in February and was completed on October 4.
A total of 364,143 cubic meters of materials have been dredged, which occupied some 11 hectares along the riverbank and restored Magapit Narrows’ riverbank depth by three meters. This has exceeded the target of 344,304 cubic meters of dredged materials.
