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 beločela gos. It is one of the few known breeding grounds in Ireland of the žvižgavka. The reglja can be seen on occasion. And it is a very good place to spot accidental visitors from America, such as ameriška žvižgavka, and from Europe, such as črna čigra.
In winter you can find Greenland beločela gos (nationally important numbers) and labod pevec are regular in small numbers. There are often large numbers of žvižgavka, whilst mlakarica, kreheljc, žličarica, čopasta črnica and sivka will also be present. There is a good chance of dolgorepa raca and konopnica, which are not easy to find in Galway. Winter waders include large numbers of zlata prosenka and priba , with veliki škurh, rdečenogi martinec, črnorepi kljunač and spremenljivi prodnik as a supporting cast. In autumn there are often rarer waders if water levels are favourable. Birds like mali rumenonogi martinec, močvirski martinec, togotnik, srpokljuni prodnik, puklež and dular 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.
