Swansea Bay

Swansea Bay (Welsh: Bae Abertawe) is a bay on the Bristol Channel on the southern coast of Wales. Places on the bay include Swansea and Port Talbot. The River Neath, River Tawe, River Afan, River Kenfig and Clyne River flow into the bay.

Swansea Bay (and upper reaches of the Bristol Channel) experience a large tidal range. The shipping ports in Swansea Bay are Swansea Docks, Port Talbot Docks and Briton Ferry wharfs.

Oyster fishing was once an important industry in Swansea Bay, employing 600 people at its height in the 1860s. However, overfishing, disease and pollution had all but wiped out the oyster population by 1920. In 2005 plans were announced to reintroduce the Oyster farming industry.

The bay is lined with sandy beaches. Each stretch of beach within the bay has its own individual name:

For the last two decades of the 20th century, the bay was blighted by pollution, partly from the surrounding heavy industry and partly from sewerage outlets being sited at inappropriate locations including the main one that was located just seaward of Mumbles Lighthouse. A pumping station inside the cliff adjacent to Knab Rock brought all of Swansea city's effluent in a raw form to this point. Adding to the problem was the natural current flow of the waters in the Bay which often did not move the polluted waters further out to sea. Ironically, the outgoing tide did not carry the raw sewage down the adjacent Bristol Channel, but instead cause it to be sucked in around the circumference of the Bay and only then out down the Channel. If not fully discharged on that tide, the incoming tide would then push the same effluent up the Channel, and once again circulate around the Bay. Efforts were made by the local authority to reduce the pollution in the Bay but care had to be taken to ensure the pollution did not move to the popular beach resorts in south Gower instead.
