Suir

The River Suir (/ʃʊər/ SHOOR; Irish: an tSiúir [ənʲ ˈtʲuːɾˠ] or Abhainn na Siúire [ˌəun̠ʲ n̪ˠə ˈʃuːɾʲə]) is a river in Ireland that flows into the Celtic Sea through Waterford after a distance of 185 kilometres (115 mi). The catchment area of the Suir is 3,610 km. Its long-term average flow rate is 76.9 cubic metres per second (m/s), about twice the flow of either the River Barrow (37.4 m/s) or the River Nore (42.9 m/s) before these join, but a little less than the Barrow's flow when it meets the Suir 20 km downstream (over 80 m/s).

Popular with anglers, it abounds in brown trout and salmon. Although the Suir holds the record for a salmon taken from an Irish river (weighing 57 lb/26 kg, taken on a fly in 1874), as has been the case in many other Atlantic rivers, salmon stocks have been in decline in recent years.
