Description
Rahasane turlough is the largest surviving turlough (an intermittent lake) in Ireland. It is an important location for migrating birds, and wintering ground for the Oie rieuse. It is one of the few known breeding grounds in Ireland of the Canard siffleur. The Sarcelle d'été can be seen on occasion. And it is a very good place to spot accidental visitors from America, such as Canard d'Amérique, and from Europe, such as Guifette noire.
In winter you can find Greenland Oie rieuse (nationally important numbers) and Cygne chanteur are regular in small numbers. There are often large numbers of Canard siffleur, whilst Canard colvert, Sarcelle d'hiver, Canard souchet, Fuligule morillon and Fuligule milouin will also be present. There is a good chance of Canard pilet and Canard chipeau, which are not easy to find in Galway. Winter waders include large numbers of Pluvier doré and Vanneau huppé , with Courlis cendré, Chevalier gambette, Barge à queue noire and Bécasseau variable as a supporting cast. In autumn there are often rarer waders if water levels are favourable. Birds like Chevalier à pattes jaunes, Chevalier sylvain, Combattant varié, Bécasseau cocorli, Bécassine sourde and Pluvier guignard have been seen.

A turlough is a karst lake, which has no surface outlet and is surrounded on all sides by rising land. At Rahasane the drainage has been modified in that since the nineteenth century the Dunkellin river has followed an artificial channel downstream of the turlough, but part of the flow continues to go underground, via a natural sink, into the underlying limestone. Rahasane consists of two basins which are connected at times of flood but separated as the waters decline. It covers 257 ha. The site comprises marshes, seasonally flooded wet meadows, with limestone outcrops and scrub at its margins. In the summer the lake empties and the basin is grazed by cattle, horses and sheep.
