Castleplunkett Turlough is a karst lake or turlough, which is water filled in winter and dry in summer. A semi-permanent stream enters from the northeast and flows towards ponds and a swallow hole in peat and rock at the centre of the turlough. The turlough has a very distinctive appearance in summer due to the presence of the black moss Cinclidotus on rocks in the basin floor.
