Donyarth or Dungarth was the last recorded king of Cornwall. He is thought to be the 'Doniert' recorded on an inscription on King Doniert's Stone, a 9th-century cross shaft which stands in St Cleerparish in Cornwall, although he is not given any title in the inscription. According to the Annales Cambriae, he drowned in 875. His death may have been an accident, but it was recorded in Ireland as a punishment for collaboration with the Vikings, who were harrying the West Saxons and briefly occupied Exeter in 876 before being driven out by Alfred the Great. Philip Payton states that one must imagine that he drowned in the River Fowey, near King Doniert's Stone.
Geology and hydrology
The upper reaches of the Fowey are mainly moorland giving way to woodland and farmland, predominantly livestock. This means that 63.6% of the catchment is grassland, with a further 18.3% woodland and 10.7% arable land. Of the remaining 7.5%, 2.6% is urban or built-up areas, 2.5% is mountain, heath and bog and the remainder is inland waters. The catchment area of the River Fowey covers a total of 41,800 acres consisting of kaolinised granite on Bodmin Moor, Devonian slates and grits, and valley gravels. Data collected by the National Water Archive shows that average flow at the Restormel monitoring station is 4.78 cubic m/s and is affected by the reservoirs at Colliford and Sibleyback and by abstraction of water for public supply. The former quarry of the Glynn Valley China Clay Works has closed down and is now flooded. It was in operation from the 1940s but since 2015 the site has been used for camping.
Wildlife and conservation
The river runs through two Sites of Special Scientific Interest, one of which is also part of a National Nature Reserve. The Upper Fowey SSSI is a floodplain on the southern slopes of Bodmin Moor and is designated for its wet heath vegetation and herbaceous valley-floor mire communities. Lower down the river at Golitha Falls part of the woodland is designated a NNR and is within the Draynes Wood SSSI. At this point the river runs through a gorge and is of particular importance for ″lower plants″ such as liverworts, mosses and lichens. Golitha is derived from the Cornish word for obstruction. There is a 1- riverside walk, from the visitor car park. Golitha Falls is the site of Wheal Victoria copper mine
Recreation
The Fowey valley is designated as an Area of Outstanding Natural Beauty so many hikers, holidaymakers and tourists visit the places of interest and eat freshly caught fish. The river has very pleasant sites and special paths made for hiking and walking along the banks and in the countryside surrounding the towns. The River Fowey is famous for its sailing because of its natural harbour. In the past it has been visited by up to 7,000 yachts in one season. Almost all sections of the river have been paddled by kayakers and canoeists: the whitewater sections high up on the moor, all the way down to the estuary. Fowey has an excellent local chandlery. Many fish can be caught in the River Fowey so many fishermen come to enjoy the excellent fishing conditions.
