Lough Arrow SAC is a protected freshwater lake and surrounding wetland habitat in northwest Ireland, known for its rich biodiversity, scenic beauty, and important bird and aquatic life conservation value.
Lough Arrow Special Area of Conservation (SAC) encompasses the freshwater lake of Lough Arrow and its surrounding habitats, straddling Counties Sligo and Roscommon in Ireland. The SAC protects approximately 2,353 hectares of diverse ecological environments including freshwater lake waters, reedbeds, marshes, bogs, and wet woodland. Lough Arrow is a deep oligotrophic lake, meaning it is nutrient-poor but supports high-quality habitats important for a wide range of species. It is notable for its clear waters and supports populations of freshwater fish such as brown trout and pike, as well as important migratory and wintering waterfowl including whooper swan, goldeneye, and teal. The area also hosts rare plants and invertebrates associated with its clean lake environment and wet woodland, including some species of conservation concern. Outdoor recreation here is largely centered on bird watching, nature photography, angling, and hiking along the lake's edge and surrounding countryside. The quiet, unspoiled environment offers peaceful scenic vistas of the lake, island clusters, and bogland beyond. Historic sites and small settlements nearby add cultural richness to visits. The SAC status helps ensure protection from development pressures and maintains the habitat quality for wildlife. Visitors find Lough Arrow ideal for low-impact outdoor experiences focused on nature observation and tranquil waterside relaxation.
