The Three Sisters (Ireland)

The rivers fan out to drain a large portion of the southern part of the island, including Counties Tipperary, Carlow, Kilkenny, Wexford and Waterford, among others.

[1] The combined long term average flow rate of the Three Sisters into Waterford Harbour is 157 m3/s, almost half of which is made up of the Suir's (76.9 m3/s), followed by the Nore's (42.9 m3/s) and the Barrow's (37.4 m3/s).

The Nore joins the Barrow some four kilometres north of New Ross and the combined waters of the three sisters that can be seen from Cheekpoint.

In ancient times, the area bounded by the Suir and the Barrow formed the Kingdom of Ossory.

The first, the gentle Shure that making way By sweet Clonmell, adorns rich Waterford; The next, the stubborne Newre, whose waters gray, By faire Kilkenny and Rosseponte boord, The third, the goodly Barow, which doth hoorde Great heaps of Salmons in his deepe bosome: All which long sundred, doe at last accord To ioyne in one, ere to the sea they come, So flowing all from one, all one at last become.
