The River Tone is a river in the English county of Somerset. The river is about long. Its source is at Beverton Pond near Huish Champflower in the Brendon Hills, and is dammed at Clatworthy Reservoir. The reservoir outfall continues through Taunton and Curry and Hay Moors, which are designated as a Site of Special Scientific Interest. Finally, it flows into the River Parrett at Burrowbridge. An act of Parliament granted in 1699 authorised work that made the river navigable as far as Taunton. The act specified that profits should be used to benefit the poor of Taunton, but the Proprietors succeeded in avoiding their obligation until 1843, when they used the proceeds from the sale of the navigation to fund a wing of the Taunton and Somerset Hospital, and to aid the Taunton Market Trust. The Bridgwater and Taunton Canal opened in 1827, which provided an easier route than the river, and protracted legal battles followed over ownership of the river and water rights for the canal. These were not finally resolved until 1832, when the Canal Company formally took over the river navigation. The ability to navigate the river gradually deteriorated, not helped by the abandonment of the River Parrett as a navigation in 1878. Following flooding in Taunton in 1960, much of the river between there and its mouth was straightened, and the navigation locks were removed. That at Ham was blown up by the Territorial Army. Navigation rights were repealed in 1967. == Course == The river is about long.〔(【引用サイトリンク】url=http://somersetrivers.org/index.php?module=Content&func=view&pid=23 )〕 Its source is at Beverton Pond.〔(【引用サイトリンク】url=http://www.everythingexmoor.org.uk/encyclopedia_detail.php?ENCid=134 )〕 Over its first it follows a south-easterly course and drops around before discharging into Clatworthy Reservoir, which also impounds the waters of 5 other streams. The river continues as the outflow from the main dam of the reservoir, passing to the west of the village of Clatworthy before following a southerly course which passes to the east of Huish Champflower. The river enters a steeply wooded section at Washbattle bridge.〔(【引用サイトリンク】url=http://www.tauntondeane.gov.uk/irj/go/km/docs/CouncilDocuments/TDBC/Documents/Heritage%20and%20Landscape/Circular%20Walks/20061101Chipstable.pdf )〕 The B3227 road from Wiveliscombe crosses from the east to the west side of the valley at Waterrow bridge. By the time it reaches Stawley bridge and turns south-east,〔 it has lost another and is just above sea level. At Tracebridge, the river turns to the north-east and then the north. Here the course of the derelict Grand Western Canal crossed the Tone on an aqueduct which now carries a footpath.〔(【引用サイトリンク】url=http://www.gracesguide.co.uk/Tone_Aqueduct_(Grand_Western_Canal) )〕〔(【引用サイトリンク】url=http://www.tauntondeane.gov.uk/irj/go/km/docs/CouncilDocuments/TDBC/Documents/Heritage%20and%20Landscape/West%20Deane%20Way/West%20Deane%20Way%20-%20Walk%203%20-%20East%20Nynehead%20-Tonedale.pdf )〕 The river passes over weirs at Greenham, Tone and Nynehead, after which it is crossed by the aqueduct of the Grand Western Canal and the railway, both on their own routes to Taunton. A disused bridge, constructed in 1817,〔(【引用サイトリンク】url=http://www.somerset.gov.uk/EasySiteWeb/GatewayLink.aspx?alId=41817 )〕 spans the river at Nynehead.〔 Nynehead Bridge〕 The river turns to the north-east near Bradford on Tone, with its two listed bridges, including the Bradford Bridge which was originally built by the 15th century,〔 Bradford Bridge〕〔 Hele Bridge, Bradford〕 and then to the east near Upcott bridge, where there were two mills. At Roughmoor its course is crossed by Silk Mills Road. There is a scheme to make the river navigable from here to the town centre as a way of encouraging transport with less environmental impact. The French weir in Taunton is the head of navigation as boats can not be taken upstream of this point. As it makes its way through the town centre to Firepool weir and the junction with the Bridgwater and Taunton Canal, it passes under the North Bridge, which was constructed in 1895,〔 Tone Bridge〕 and Priory Bridge Road. Next comes the A358 Obridge viaduct, the A38 Bathpool Bridge and the M5 motorway bridge. Firepool weir was reconstructed in 1967 as part of the plans to straighten the river through the town centre and down to Bathpool in order to provide better flood defences. These works swept away the remains of the original navigation. There is a disused five-arched railway bridge built in 1863 at Creech St Michael.〔 Five Arch Bridge, Creech St Michael〕 Nearby is the aqueduct that carried the Chard Canal over the river from 1842 until 1866. The Brewhouse Theatre & Arts Centre, is close to the riverside.〔 Brewery House〕 Ham weir stands as a reminder of the location of the lock there. After Knapp bridge, the sluice at Newbridge marks the upper tidal limit of the river. Curry and Hay Moors, an area of low-lying fenland close to the river, are a Site of Special Scientific Interest.〔(【引用サイトリンク】 work=English Nature )〕 A railway bridge carries the Taunton to Castle Cary railway line over the river, after which is the Curry Moor pumping station. Two more road bridges at Athelney and Stanmoor cross the river before it joins the River Parrett at Burrowbridge, where the junction is overshadowed by Burrow Mump.〔 Burrow Mump Church〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「River Tone」の詳細全文を読む スポンサード リンク
