Other Site Characteristics

Lough Mask, at over 8,000 ha, is the sixth largest lake in the country. It extends for over 14 km along its long axis and is on average about 5 km in width. The underlying geology is of Carboniferous limestones, with some shales and sandstones. The main inflowing rivers are the Cloon, Robe and the stream from Lough Carra to the north-east. The main outflow is to Lough Corrib to the south. The lake is shallow off the eastern shore but considerably deeper off the western where there is a long narrow trench with a maximum depth of 58 m. The water of the lake is moderately hard. During the 1990s, the trophic status of Lough Mask has changed from oligotrophic to mesotrophic due to a steady increase in phytoplankton growth. The eastern part of the lake is edged by a low-lying shoreline which is subject to winter flooding. An intricate mixture of plant communities has developed on the limestone, with bare pavement, scrub-dominated pavement, dry grassland and heath. The western shoreline is less diverse and lacks the limestone communities. Islands are a feature of the lake, especially in the south-east sector.

4.2 Quality and importance

Lough Mask is one of the most important sites in the country for nesting Larus ridibundus, Larus canus and Larus fuscus, accounting for 8.4%, 1.7% and 10% of the respective national totals. It also supports a nationally important colony of Sterna hirundo. In winter the site has a range of waterfowl, especially diving duck, with the Aythya fuligula population being of national importance. It also supports Cygnus cygnus and is visited at times by part of the Erriff / Derrycraff population of Anser albifrons flavirostris. The lake has a population of Salvelinus alpinus, a Red Data book species and is an important site for Lutra lutra. Lough Mask is an important salmonid fishery.
