<P> A turlough , or turlach , is a type of disappearing lake found mostly in limestone areas of Ireland , west of the River Shannon . The name comes from the Irish tuar , meaning `` dry '' , with the suffix - lach , meaning `` a place '' ( in an abstract sense ) . The - lach suffix is often mistakenly spelled and / or thought to refer to the word loch , the Irish , Scottish Gaelic and Scots word for `` lake '' . The landforms are found in Irish karst ( exposed limestone ) areas . </P>
