Hell&High Water'' has a complex hydrology which includes drainage from at least five small sinks on the eastern Marlbank (Gortmaconnell Pot, Little Gortmaconnell Pot, Smokey Mountain Sink and two unnamed sinks at Brookfield have been dye traced to Cascades); sections of the Owenbrean River upstream of its main sink at Pollasumera; and most notably Goat Pot, Aghatirourke Pot, Pigeon Pots and Badger Pot on East Cuilcagh, nearly 3 kilometers to the southeast.
