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 Lisasta guska. It is one of the few known breeding grounds in Ireland of the Zviždara. The Grogotovac can be seen on occasion. And it is a very good place to spot accidental visitors from America, such as Američka zviždara, and from Europe, such as Crna čigra.
In winter you can find Greenland Lisasta guska (nationally important numbers) and Veliki labud are regular in small numbers. There are often large numbers of Zviždara, whilst Gluvara, Krdža, Plovka kašikara, Ćubasta patka and Riđoglava patka will also be present. There is a good chance of Šiljkan and Čegrtuša, which are not easy to find in Galway. Winter waders include large numbers of Zlatni vivak and Vivak , with Velika carska šljuka, Crvenonogi sprudnik, Muljača and Crnotrba sprutka as a supporting cast. In autumn there are often rarer waders if water levels are favourable. Birds like Mali žutonogi sprudnik, Sprudnik migavac, Sprudnik ubojica, Riđa sprutka, Mala šljuka and Planinski zujavac 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.
