Lough Melvin Special Area of Conservation

Lough Melvin straddles the border between Northern Ireland and the Republic of Ireland, encompassing parts of County Fermanagh and County Leitrim. This Special Area of Conservation (SAC) is internationally recognized for its remarkable ecology, especially as one of the most biologically diverse lakes in Europe. It covers approximately 24 square kilometers and is renowned for housing unique native fish species, including the rare Gillaroo and Sonaghan trout, as well as the distinctive Sheltered White-clawed Crayfish. The lake’s clear oligotrophic waters create a fragile habitat that supports Cyanobacteria and various aquatic plants, contributing to its exceptional water quality and clarity. Historically, Lough Melvin has been a vital natural resource for local communities, boasting cultural significance and ancestral ties to traditional angling and rural livelihoods. Outdoor enthusiasts are drawn to the lake for its world-class fly-fishing, particularly for brown trout and native species, while the surrounding area offers birdwatching, gentle hiking, and stunning scenery characterized by rolling hills and serene shoreline habitats. The SAC designation ensures ongoing conservation efforts to protect the lake’s unique species and habitats, balancing recreational use with environmental stewardship. Visitors experience a peaceful, unspoiled landscape rich in wildlife, where responsible tourism sustains the ecological integrity of this treasured site.
