River Camel
The River Camel ((コーンウォール語:Dowr Kammel), meaning ''crooked river'') is a river in Cornwall, England, UK. It rises on the edge of Bodmin Moor and with its tributaries drains much of North Cornwall. The river flows into the eastern Celtic Sea between Stepper Point and Pentire Point having covered about 30 miles. The river is tidal upstream to Egloshayle and is popular for sailing, birdwatching and fishing. The name ''Camel'' comes from the Cornish language for 'the crooked one', a reference to its winding course. Historically the river was divided into three named stretches. Heyl ((コーンウォール語:Heyl), meaning ''estuary'') was the name for the estuary up to Egloshayle, the River Allen ((コーンウォール語:Dowr Alen), meaning ''shining river'') was the stretch between Egloshayle and Trecarne, whilst the Camel was reserved for the stretch of river between its source and Trecarne.〔Weatherhill, Craig. A Concise Dictionary of Cornish Place-names, 2009.〕
==Geology and hydrology==
The River Camel rises on Hendraburnick Down (UK Grid Reference SX135875) on the edge of Bodmin Moor, an area which forms part of the granite spine of Cornwall. The river's course is through upper and middle Devonian rocks, predominantly the Upper Delabole Slates, Trevose Slates and Polzeath Slates that stretch to the coast, although Pentire Head is composed mainly of pillow lavas.〔(【引用サイトリンク】 publisher = Cornwall Regionally Important Geological/Geomorphological Sites Group )〕 The only active quarry in the River Camel catchment area is at Delabole〔(【引用サイトリンク】 publisher = British Geological Survey )〕 and there has been mining for lead and antimony on Pentire Head, and building stone at various locations. Further inland mines surrounding the Camel and its tributaries produced lead, copper and iron, while Mulberry Mine near Ruthernbridge produced tin.
The source of the Camel is at above sea level〔(【引用サイトリンク】 publisher = Natural Environment Research Council )〕 and it has an average incline of 7m/km.〔 The upper reaches of the Camel and its tributaries are mainly moorland giving way to woodland and farmland, predominantly livestock.〔 This means that 64.8% of the catchment is grassland, with a further 14.8% arable land and 12.9% woodland. Of the remaining 7.4%, 4.5% is through urban or built-up areas, 2.7% is mountain, heath and bog and the remainder is inland waters.〔(【引用サイトリンク】 publisher = Westcountry Rivers Trust )〕
The Camel's catchment area covers 413 km2〔 on the western side of Bodmin Moor, and is mainly Devonian slates and granite,〔(【引用サイトリンク】 publisher = Centre for Ecology & Hydrology )〕 with some shales and sandstones.〔 Water volumes are affected by the reservoir at Crowdy Marsh, by abstraction of water for public supply, and by effluent from the sewage system around Bodmin. Data collected by the National Water Archive shows that water flow in the River Camel for 2006 was considerably below average. This correlates with reduced rainfall, particularly between the months of June and September.〔(【引用サイトリンク】 publisher = Centre for Ecology & Hydrology )〕
