River Nore

The River Nore (Irish: An Fheoir [ə ˈn̠ʲoːɾʲ]) is one of the principal rivers (along with the River Suir and River Barrow) in the South-East Region of Ireland. The 140-kilometre-long (87 mi) river drains approximately 2,530 square kilometres (977 mi2) of Leinster and Munster, that encompasses parts of three counties: Tipperary, Laois and Kilkenny. Along with the Suir and the Barrow, it is one of the Three Sisters group of rivers. Starting in the Devil's Bit Mountain, County Tipperary, the river flows generally southeast, and then south, before its confluence with the River Barrow at Ringwood, and the Barrow railway bridge at Drumdowney, County Kilkenny, which empties into the Celtic Sea at Waterford Harbour. The long term average flow rate of the River Nore is 42.9 cubic metres per second (m3/s). The river is home to the only known extant population of the Nore freshwater pearl mussel, a critically endangered species. Much of the river's length is designated as a Special Area of Conservation.
