The River Tawe is a river in south Wales which meets the sea at Swansea (Abertawe in Welsh). The river flows from its source in the old red sandstone hills in a more or less south-westerly direction. The only large tributary is the River Clydach. The Tawe passes through a number of towns and villages including Ystradgynlais, Ystalyfera, Pontardawe and Clydach.
The lower part of the valley was intensely industrialised in the 18th and 19th centuries and was especially impacted by metal refining and working and to a much lesser extent by porcelain manufacture. Large areas of the lower valley remain contaminated by industrial spoil containing copper, lead, nickel and zinc. The only significant extant relic of those times is a major nickel refinery at Clydach which is part of the Canadian company INCO. The quality of the river has now greatly improved. Large salmon and trout swim up the river to spawn.
In 1992, a barrage was built at the mouth of the river.
