The NIA Apayao Irrigation Management Office (IMO) is currently undertaking dredging operations to remove accumulated aggregates upstream of the West Apayao Abulug Irrigation System (WAAIS) Dam along the Apayao River in Barangay Swan, Pudtol, Apayao.

By clearing sediment and aggregate buildup near the diversion structure, water can flow more freely and efficiently toward the intake, reducing the risk of water shortages during periods of limited rainfall and help mitigate the potential impacts of the El Niño phenomenon, according to NIA.
