The study determined the environmental impact on the Cagayan de Oro River of the environmental projects as assessed by the 16 river barangay communities of Cagayan de Oro City, the local officials of the government, the Local Government Units (LGUs) and the various agencies of the government. The projects assessed were dredging, aqua-culture, tree planting, and clean – up drive. These projects obtained very satisfactory assessment. This assessment indicates the projects’ positive environmental impact on the Cagayan de Oro River. Ensuring the full implementation and success of the projects is the active involvement of the river barangays. The participation of the various institutions in the different environmental projects clearly shows that Cagayan de Oro City has on its top agenda the preservation and protection of the Cagayan de Oro River. Vital to the sustainability of the projects are networking and people empowerment.
