river Exe

File:River Exe at Exeter Quay.jpg

The river's name derives from *uɨsk, a Common Brittonic root meaning "abounding in fish", and a cognate of both the Irish iasc, meaning "fish", and pysg, the plural word for "fish" in Welsh.{{cite book |title=The Concise Oxford Dictionary of English Place-names |author=Eilert Ekwall |publisher=OUP |location=Oxford [Eng.] |year=1981 |pages=171 |isbn=0-19-869103-3}}Owen, H.W. & Morgan, R. 2007 Dictionary of the Place-names of Wales Gomer Press, Ceredigion; Gwasg Gomer / Gomer Press; page 484. The same root separately developed into the English Axe and Esk, the Welsh Usk, though not, as some have claimed, the word whisky, this latter being from the Classical Irish/Gaelic {{lang|ghc|uisgi}} "water" (the fuller phrase being {{lang|ghc|uisgi betha}}; {{langx|ga|uisce beatha}}; {{langx|gd|uisge beatha}}; "{{lang|la|aqua vitae}}" ("water of life")).

The river's name occurs in Exeter ("fortress on the Exe") and many other settlements along its course, including Exford, Up Exe, Nether Exe, Exwick, Exton, Exminster, and Exebridge,{{cite book | url=https://books.google.com/books?id=w_B0Ouj5VC0C&pg=PT294|title=A Dictionary of British Place-Names | publisher=Oxford Paperbook Reference|author=A.D.

The seaside town of Exmouth is at the east side of the estuary mouth, and Dawlish Warren is at the west, with its long sand spit extending across the mouth.

The river fuelled Exeter's growth and relative importance in medieval times. The city's first industrial area was developed at Exe Island, which was created in the 10th century by digging a series of leats into the sandy and marshy land bordering the river. The island became home to numerous watermills producing paper and textiles.{{cite web

Tides on the river are limited at Trews Weir in Exeter, two kilometres upstream of Countess Wear, the site of a former weir commissioned by the Countess of Devon in the 13th century.{{cite web

}} The Exeter Canal bypassed this weir to enable ships to reach Exeter Quay. At high tide, the estuary forms a large body of water that is heavily used for water sports, especially sailing, windsurfing and water skiing.

Railways run along both sides of the estuary. The Avocet Line from Exeter to Exmouth on the eastern side, and the South Devon main line on the western. The latter is on a causeway, the South Devon Railway sea wall from Powderham to Dawlish Warren. The Exmouth to Starcross Ferry carries passengers across the mouth of the estuary during the summer months, linking the harbour at Exmouth with a pier adjacent to Starcross railway station on the South Devon main line.

At low tide, extensive mud flats are exposed, and these are an important feeding source for wading birds. Along with other rias in South West England, the Exe estuary is an important site for wintering waders. Dawlish Warren is a favoured site for birdwatching. The river has a low pH but does not suffer from a serious acid rain problem. It is populated with wild brown trout, and in the lower reaches coarse fish including dace, chub, perch, roach, pike and bream and some grayling, the average size being {{convert|8|-|10|oz|g}}. There is a run of Atlantic salmon and a sparse run of sea trout. Just {{convert|150|m|ft}} below the union of the River Barle is Black Pool, which is one of the best, and highest salmon pools on the river. The smaller fish species present include stone loach and there are good reasons to assume others are present.

In 2008 the Environment Agency embarked on a project to clear vegetation from the river in Exeter as well as make way for flood defence work. In order to do the former the water level was lowered further than during the worst droughts that Exeter had seen.{{cite web
