Is the Firth of Tay a natural waterway?
Firth of Tay
The Firth of Tay (Scottish Gaelic: Linne Tatha) is a firth in Scotland between the council areas of Fife, Perth and Kinross, the City of Dundee and Angus, into which Scotland's largest river in terms of flow, the River Tay empties. The firth has a maximum width of at Invergowrie.
Perth Bridge
Perth Bridge (also known as Smeaton's Bridge, locally, the Old Bridge and in the local dialect of Scots, "the Auld Brig") is a toll-free bridge in the city of Perth, Scotland. It spans the River Tay, connecting Perth, on the western side of the river, to Bridgend, on its eastern side, carrying both automotive and pedestrian traffic of West Bridge Street (the A85). It is a Category A listed structure.
Firth of Tay
The Firth of Tay in Antarctica was discovered in 1892-93 by Captain Thomas Robertson of the Dundee whaling expedition and named by him after the one in Scotland. He also named nearby Dundee Island in honour of the main city on the firth.
River Dochart
Coming from Ben Lui, it flows east out of Loch Dochart and through the glen of the same name. At Killin just before it enters Loch Tay are the Falls of Dochart. The river is sometimes also considered to be a part of the upper reaches of the River Tay.
Tye River
The Tye River is home to dozens of species of fish and other aquatic life, including American eels, small and largemouth bass, and native mussels. A dam was removed in 2007 to help facilitate fish migration. According to an official of the Virginia Department of Game and Inland Fisheries, "Removing the dam will increase the passage possibilities, and hopefully the populations of all these species. It will also allow for increased access for anglers, paddlers and boaters."
River Foyle
The River Foyle and Tributaries Area of Special Scientific Interest (ASSI) includes the River Foyle and its tributaries i.e. that part of the River Finn which is within Northern Ireland, the River Mourne and its tributary the River Strule (up to its confluence with the Owenkillew River) and the River Derg, along with two of its sub-tributaries, the Mourne Beg River and the Glendergan River. The area encompasses 120 km of watercourse and is notable for the physical diversity and naturalness of the banks and channels, especially in the upper reaches, and the richness and naturalness of its plant and animal communities. Of particular importance is the population of Atlantic Salmon, which is one of the largest in Europe. Research has indicated that each sub-catchment within the system supports genetically distinct populations.
River Tay
The Tay is internationally renowned for its salmon fishing and is one of the best salmon rivers in the United Kingdom, and western Europe, attracting anglers from all over the world. The lowest ten miles of the Tay, including prestigious beats like Taymount or Islamouth, provides most of the cream of the Tay. The largest rod caught salmon in Britain, caught on the Tay by Miss Georgina Ballantine in 1922, weighing , retains the British record. The river system has salmon fisheries on many of its tributaries including the Earn, Isla, Ericht, Tummel, Garry, Dochart, Lyon and Eden. Dwindling catches include a 50% reduction in 2009 so the Tay District Salmon Fisheries Board ordered a catch-and-release policy for females all season, and for males until May, beginning in the January 2010 fishing season. Research by the North Atlantic Salmon Conservation Organisation has shown that the number of salmon dying at sea has doubled or trebled over the past 20 years, possibly due to overfishing in the oceans where salmon spend two years before returning to freshwater to spawn. The widespread collapse in Atlantic salmon stocks suggests that this is not solely a local problem in the River Tay.
Tye River (Washington)
The Tye River is used by chinook and coho salmon. Adults migrate upstream as far as Alpine Falls. Spawning occurs mostly in the mainstem river. Some coho spawn in the lower parts of a few tributary streams such as Alpine Creek. Juvenile salmon rear throughout the accessible waters of the river basin. No anadromous fish are found above Alpine Falls as it is a total barrier to fish migration. Sunset Falls on the South Fork Skykomish River, below the mouth of the Tye River, is also a total barrier to fish migration. All anadrmous fish above Sunset Falls, which includes the entire Tye River basin, are present only as a result of a trap and haul operation initiated in 1958 by the Washington Department of Fisheries. Between July and December fish are trapped below the falls, trucked above, and returned to the South Fork Skykomish.
River Tay
The Tay is unusual amongst Scottish rivers in having several major tributaries, notably the Earn, the Isla, the River Tummel, the Almond and the Lyon.

Invergowrie
Invergowrie is located on the northwest bank of the Firth of Tay, with the Invergowrie Bay located just to the east and south of the village.
Extreme points of Scotland
Many points are on, or near sea level, but due to high rainfall, there are no natural dry pieces of land below sea level - see rivers and lochs below.The longest river in Scotland is the River Tay (117 mi, 188 km).
Afon Dyfrdwy (River Dee)
Afon Dyfrdwy (River Dee) is a Site of Special Scientific Interest in the preserved county of Clwyd, north Wales. The river begins in Parc Cenedlaethol Eryri, in Snowdonia, Wales. From there, it flows northeast to Corwen, goes eastward past Llangollen, and continues east through Chester, England. It empties into Aber Dyfrdwy, an estuary that forms the border between the Wirral Peninsula in north-west England and Flintshire in north-east Wales. The river has been designated a Designated Special Area of Conservation due to its role as a habitat for Atlantic Salmon and Floating Water Plantain.
Tees Barrage International White Water Course
The Tees Barrage International White Water Course, originally the Teesside White Water Course, is an artificial whitewater course on the north bank of the River Tees, in North East England.
It is part of the Tees Barrage and is located in the Stockton-on-Tees district, accessible by road only from Thornaby-on-Tees and best accessed by the A66.
The course was built in 1995 at a cost of £2m.
The course is now open once more under the new name TBIWWC (Tees Barrage International White Water Centre).
River Earn
The River Earn () in Scotland leaves Loch Earn at St Fillans and runs east through Strathearn, then east and south, joining the River Tay near Abernethy. The Earn is about long. It passes by Comrie, Crieff (where it is joined by the Pow of Inchaffray) and Bridge of Earn. The river is fast flowing, with many shoals, whilst the surrounding land is generally flat and is occasionally subject to flooding.
Aberfeldy, Perth and Kinross
The Aberfeldy Footbridge over the River Tay is constructed entirely of composite materials. It connects two holes of the town's golf course on either side of the River Tay.
York Factory
York Factory is located on the north bank of the Hayes River about inland. The mouth of the Nelson River is to the north, across "Point of Marsh". The Hayes is a more practical canoe route, although the Nelson is much larger (it drains Lake Winnipeg). Seagoing ships anchored at Five Fathom Hole from the fort due to the shallow bottom, and goods were transferred by smaller boats. The Shamattawa Airport and Gillam Airport are close.
River Tame, West Midlands
Skirting to the north of Castle Bromwich, it leaves Birmingham to the north-east at Park Hall Nature Reserve, passing Water Orton in Warwickshire. At Hams Hall, immediately after its confluence with the River Blythe and the little River Bourne, it turns sharply to take up a northward course, and soon feeds into the large complex of water purification lakes at Lea Marston that now make up Kingsbury Water Park. It then crosses into Staffordshire, flowing through Middleton Lakes RSPB reserve in a wide valley between Drayton Bassett to the west and Dosthill to the east. It then flows under Watling Street to the east of Fazeley, and under an aqueduct carrying the Coventry Canal. It continues northward to Tamworth, which takes its name from the river, where it is joined by the River Anker immediately to the east of Lady Bridge beneath the strategically positioned Tamworth Castle. The river continues its generally northward route past Hopwas, Comberford and Elford until it arrives at the National Memorial Arboretum where it forms the boundary between this and the Croxall Lakes Nature Reserve. After this, it flows under the railway at Wichnor Viaduct to its confluence with the Trent near Alrewas. The eventual outflow is into the North Sea, via the Humber Estuary. When the Tame and Trent meet, the Tame is the bigger river, the Trent effectively joining it as a tributary. However, the Trent being the "longer" river at that point is considered the more senior, and so the combined river bears its name.
The catchment of the Tame covers an area of nearly 1500 km² and contains a population of about 1.7 million people. Approximately 42% of the Tame basin is urbanised, making it the most heavily urbanised river basin in the United Kingdom.
River Tay
A section of the Tay surrounding the town of Dunkeld is designated as a national scenic area (NSA), one of 40 such areas in Scotland, which are defined so as to identify areas of exceptional scenery and to ensure its protection by restricting certain forms of development. The River Tay (Dunkeld) NSA covers 5,708 ha.
Slapton Ley
Slapton Ley is the largest natural freshwater lake in south-west England being long and has two sections; the Lower Ley and the Higher Ley. The ley is fed by streams and a small river, The Gara, that flows into the Higher Ley. The site is a National Nature Reserve, a Site of Special Scientific Interest and a Geological Conservation Review site. The nature reserve covers over .
Lady Bay, Nottinghamshire
Lady Bay is on the flood plain of the River Trent and has benefited over the years from progressively upgraded flood defences. Between these flood defences (to the north of Holme Road) and the River Trent is an area of statutory washlands known as The Hook.
This meadowland provides a habitat for wildlife and a recreational area for local residents; it floods dramatically every 5–10 years, so will never be developed. The Hook was declared a Local Nature Reserve in December 2009. A 'Friends' group has been established and volunteers work to manage and maintain the site.
Inner Tay Estuary
The Inner Tay Estuary, the inner, western part of the Firth of Tay, stretching from the Tay Railway Bridge in the east to the Queen's Bridge over the River Tay in Perth and the bridge in Bridge of Earn on the River Earn. The estuary is one of the largest in eastern Scotland and is up to 2.5 km wide. The estuary consists primarily of inter-tidal sand and mud flats that extend seaward out to the main channel of the estuary, the majority of which lie on the northern shore. Landward of these are saltmarsh and "Phragmite"s reedbeds. There are two large islands: Mugdrum Island opposite Newburgh and Moncreiffe Island immediately below Perth. The narrow form of the estuary and the large volume of freshwater from the Rivers Tay and Earn restrict the influence of salt water west of the Tayport narrows. Much of the tidal water in the estuary is freshwater or mildly brackish.
Environment of Scotland
Scotland is bordered to the east by the North Sea and to the north and west by the Atlantic Ocean. Scotland has many rivers, lochs, reservoirs and estuaries. The River Tay is Scotland's longest river and is 193 kilometres (120 mi) long. Lakes in Scotland are known as lochs, with the exception of the Lake of Menteith and a few man-made lakes. The largest loch is Loch Lomond and is 71.1 km (27.5 sq. mi) in area and is Britain's largest freshwater body.
Lea Valley Walk
Amenities in Lea Bridge Road area include the Lee Valley Ice Centre, riding stables and two nature reserves; the Middlesex Filter Beds and the Waterworks Nature Reserve. The river splits at the Middlesex Filter Beds Weir where a section of the River Lea's natural channel flows in an easterly direction can be found. Still following the navigation which is known as the Hackney Cut at this point, the path passes the site of the redundant Pond Lane Flood Gates. The walk crosses a small footbridge to the east bank adjacent to Hackney Marshes. Passing under A106 road Eastway and then the East Cross Route. The path passes nearby Hackney Wick Stadium. The walk passes under the North London Line (now London Overground) railway and Rothbury Road. The Hertford Union Canal joins the river on the west bank before crossing Victoria Park. 
Heading towards Old Ford Lock the path links to the Capital Ring walk and then passing under The Greenway and the Docklands Light Railway close to Pudding Mill Lane station. Crossing to the opposite bank at Bow Road and crossing the river at Three Mills Bridge close to Three Mills. The walk continues under the District line and Hammersmith and City line close to Bromley-by-Bow. The river forks at Bow Locks with the Lee Navigation joining the tidal section of the river known as the Bow Back Rivers through Bow Creek to its confluence with the Thames. The path now follows the Limehouse Cut and passing the disused Bromley and Britannia Stop Locks to Limehouse Basin where the walk ends. Close by is the Thames Path.
Firth
A firth is generally the result of ice age glaciation and is very often associated with a large river, where erosion caused by the tidal effects of incoming sea water passing upriver has widened the riverbed into an estuary. Demarcation can be rather vague. The Firth of Clyde is sometimes thought to include the estuary as far upriver as Dumbarton, but the Ordnance Survey map shows the change from river to firth occurring off Port Glasgow, while locally the change is held to be at the Tail of the Bank where the river crosses a sandbar off Greenock at the junction to the Gare Loch, or even further west at Gourock point.
Cheddar Yeo
The Cheddar Yeo is a small river in Somerset, England. Beneath the limestone of the Mendip Hills it forms the largest underground river system in Britain. After emerging into Cheddar Gorge it flows through the village of Cheddar, where it has been used in the past to power mills. From the Middle Ages until the 19th century the river had ports for seagoing vessels but is no longer navigable. Some of the water, which is of good quality, is diverted into Cheddar Reservoir to provide drinking water for Bristol.
Moray Firth
Basically, the Moray Firth is of tectonic origin, related to the Great Glen Fault. For some time during the glaciation, the whole of nowaday's Moray firth was a huge glacier. Nevertheless, the inner Part and its side-inlets, Cromarty Firth and Dornoch Firth, are true fjords themselves. Though there is a reasonable tide with mean tide ranges of about three metres (ten feet), only part of the rivers draining into the bay have estuaries. Masses of sediment from the adjacent mountains have formed spits around several mouths. Those of River Ness and River Carron have significantly narrowed the fjords they enter.
River Tummel
Discharging from Loch Rannoch, it flows east to a point near the Falls of Tummel, where it bends to the southeast, a direction which it maintains until it falls into the River Tay, just below Logierait, after a course of from its source in Stob Ghabbar (). Its only considerable affluent is the Garry, long, an impetuous river which issues from Loch Garry ( and above sea level). About midway in its course the Tummel expands into Loch Tummel, between which and the confluence with the Garry occur the Pass and Falls of the Tummel, which are rather in the nature of rapids, the descent altogether amounting to . Loch Tummel was previously long and deep, but with the construction of the Clunie Dam in 1950, the water level was raised by 4.5 metres, and Loch Tummel is now approximately long.
River Tay
The Tay is mentioned in William McGonagall's poems "The Tay Bridge Disaster" and "Railway Bridge of the Silvery Tay" and the German poet Theodor Fontane has mentioned the Tay in his poem ""Die Brück' am Tay". Both poems deal will the Tay bridge disaster of 1879, seeing the bridge's construction as a case of human hubris and expressing an uneasiness towards the fast technological development of mankind. It is mentioned in the Steeleye Span song "The Royal Forester". Many Rolls-Royce civil aero-engines are named after British rivers, one of which is the Rolls-Royce Tay.
Inner Tay Estuary
The 20 km or so stretch between the railway bridge and the confluence of the Rivers Tay and Earn is a site of special scientific interest. The current SSSI was notified in August 1999 and extends to 4,115 hectares or thereby.
Scottish Natural Heritage provides more information about the SSSI in its site management statement.
Ayr Lake
Ayr Lake is a land-locked freshwater fjord on Baffin Island's northeastern coast in the Qikiqtaaluk Region of Nunavut, Canada. The Inuit settlement of Pond Inlet is to the northwest and Clyde River is to the east.
River Wye
The River Wye () is the fifth-longest river in the UK, stretching some from its source on Plynlimon in mid Wales to the Severn estuary. For much of its length the river forms part of the border between England and Wales. The Wye Valley (lower part) is an Area of Outstanding Natural Beauty. The Wye is important for nature conservation and recreation.
The Rythe
The Rythe is a river or stream in north Surrey, England which is generally open and which is a natural woodland feature for approximately half of its course before being variously culverted and a suburban garden feature, passing between Thames Ditton and Long Ditton, then discharging into the Thames, its longest branch is the Arbrook which drains Arbrook Common, a woodland of the mainly wooded Esher Commons.
River Thame
The Thame's source is three streams which rise in the wide Vale of Aylesbury on the north side of the Chiltern Hills. These streams converge north-east of Aylesbury, the county town of Buckinghamshire. The Thame played a key role in the English Civil War when John Hampden (the town's Member of Parliament) led the force of Parliamentarians successfully defending Aylesbury at the Battle of Holman's Bridge, where a small road crosses the river, in 1642.
Firth of Tay
Two bridges span the firth, the Tay Road Bridge and the Tay Rail Bridge.
British Waterways
The following waterways and dockland were under British Waterways' ownership and care:The Environment Agency is the navigation authority for the non-tidal River Thames, rivers in the Fens and East Anglia and some other waterways, while the Port of London Authority is responsible for the tidal section of the River Thames. The Norfolk Broads are the responsibility of the Broads Authority. The River Cam, Basingstoke Canal, Bridgewater Canal, Manchester Ship Canal, and Chelmer and Blackwater Navigation were also outside the jurisdiction of British Waterways.
River Wye
It is also a Special Area of Conservation and one of the most important rivers in the UK for nature conservation. It is an important migration route and wildlife corridor, as well as a key breeding area for many nationally and internationally important species. The river supports a range of species and habitats covered by European Directives and those listed under Schedule 5 of the Wildlife and Countryside Act 1981. In Powys the river lies within the Radnorshire Environmentally Sensitive Area. Much of the lower valley is an Area of Outstanding Natural Beauty.
The Lower Wye has been designated as a salmonid fishery under the EC Freshwater Fish Directive. The Wye is largely unpolluted and used to be considered one of the best rivers for salmon fishing in the United Kingdom, outside Scotland. In the 1980s and 1990s salmon in the Wye declined dramatically. In 1967 the Wye rod catch was 7,864, and as recently as 1988 it was 6,401; but by 2002 it was only 357. It is now recovering from this low in response to the extensive habitat improvement work carried out by the Wye and Usk Foundation, set up to restore the spring salmon runs. In 2015 the five-year average once again climbed above 1,000 and it is now the third best salmon river in England and Wales, surpassed only by the Tyne and Wear.

River Braan
The River Braan () is a tributary of the River Tay in Scotland. 
Within the county of Perth and Kinross, it flows 11 miles (17 km) eastwards from Loch Freuchie, near Amulree, and joins the River Tay near Dunkeld.
River Tay
The first sustained and significant population Eurasian beaver ("Castor fiber") living wild in Scotland in over 400 years became established on the river Tay catchment in Scotland as early as 2001, and has spread widely in the catchment, numbering from 20 to 100 individuals in 2011. These beavers were likely to be either escapees from any of several nearby sites with captive beavers, or were illegally released, and were originally targeted for removal by Scottish Natural Heritage in late 2010. Proponents of the beavers argued that no reason exists to believe that they are of "wrong" genetic stock. In early December 2010, the first of the wild Tayside beavers was trapped by Scottish Natural Heritage on the River Ericht in Blairgowrie, Perthshire and was held in captivity in Edinburgh Zoo, dying within a few months. In March 2012 the Scottish Government reversed the decision to remove beavers from the Tay, pending the outcome of studies into the suitability of re-introduction.
List of whitewater rivers
The River Dart excepted, there is no natural whitewater in the (mainly flat) south and east of England. Here whitewater paddlers often go playboating at man made weirs. Hurley weir on the River Thames west of London is probably the most popular. There are several artificial whitewater courses, where water is pumped or diverted though a concrete channel containing obstacles to create rapids. There is a 28 m/s artificial whitewater course on the Trent at Holme Pierrepont in Nottingham (at the National Watersports Centre), a 5 m/s course on the Tees in Teesside, and smaller courses on the Nene at Northampton, and at Cardington.
River Tyne
The North Tyne rises on the Scottish border, north of Kielder Water. It flows through Kielder Forest, and in and out of the border. It then passes through the village of Bellingham before reaching Hexham.
The South Tyne rises on Alston Moor, Cumbria and flows through the towns of Haltwhistle and Haydon Bridge, in a valley often called the Tyne Gap. Hadrian's Wall lies to the north of the Tyne Gap. Coincidentally the source of the South Tyne is very close to the sources of the other two great rivers of the industrial north east namely the Tees and the Wear. The South Tyne Valley falls within the North Pennines Area of Outstanding Natural Beauty (AONB) - the second largest of the 40 AONBs in England and Wales.
The combined Tyne flows from the convergence point at Warden Rock just to the north west of Hexham, the area where the river's now thriving barbel stocks were first introduced in the mid-1980s, through Corbridge in Northumberland. It enters the county of Tyne and Wear between Clara Vale (in the Borough of Gateshead on the south bank) and Tyne Riverside Country Park (in Newcastle upon Tyne on the north bank) and continues to divide Newcastle and Gateshead for , in the course of which it is spanned by 10 bridges. To the east of Gateshead and Newcastle, the Tyne divides Hebburn and Jarrow on the south bank from Walker and Wallsend on the north bank. Jarrow and Wallsend are linked underneath the river by the Tyne Tunnel. Finally it flows between South Shields and Tynemouth into the North Sea.
River Conwy
Aber Afon Conwy is a site of special interest. It has acquired such a status due to its marine and terrestrial biology. The tidal reach of the site reaches around 16 kilometres. Its upstream boundary is south of Tal y Cafn, and the whole site encompasses Conwy Bay. The shoreline is supported by natural rock, in addition to boulder clay cliff, sand dune, salt marsh and woodland.
Roman River
The Roman River rises from springs to the west of Great Tey. Three small streams merge, before the channel passes under the Great Tey to Little Tey road. It then passes under the railway line from to and another minor road, before reaching a major bridge under both the Great Eastern Main Line and the A12 road to the north of Copford. It turns to the south-east, to reach the B1022 road at Heckfordbridge. It is joined by a tributary flowing north-eastwards from Birch, and turns again to the east, passing under the B1026 Kings Ford Bridge to the north of Layer de la Haye. The channel widens to form the mill pond for Layer de la Haye watermill. On the south bank is Roman River Valley, a nature reserve, managed by the Essex Wildlife Trust.
The Rythe
It runs under the six-lane A3 into wooded Arbrook Common there joined by three further headwaters rising in the suburban area of a suburban village with many amenities, Claygate, immediately to the east (right bank). It carries on north bounding Littleworth Common and Hinchley Wood to the Scilly Isles roundabout at part of remnant wooded Ditton Marsh, today cast as part of Esher, containing Esher railway station to which its roads (two arterial) connect and in Esher post town. It then follows the Portsmouth Road east through part of Thames Ditton proper and alongside the South Western Main Line. It receives its shorter east branch (rising in Surbiton Golf Course, Long Ditton within Elmbridge) then turns running into the Thames near Ferry Road, 800 metres north.
Lough Tay
Lough Tay (Irish: "Loch Té"), commonly called The Guinness Lake, is a small but scenic lake set on private property, in the Wicklow Mountains in County Wicklow, Ireland. It lies between the mountains of Djouce and Luggala, and is most easily viewed from above, from the R759 or the Wicklow Way as it descends past the J. B. Malone memorial. It is fed by the Cloghoge River, which then drains into Lough Dan to the south. It is not possible to visit Lough Tay without prior permission.
Tye River (Washington)
The Tye River is a river in the U.S. state of Washington. It rises near Stevens Pass in the Cascade Mountains and flows west, joining the Foss River to form the South Fork Skykomish River. Its waters eventually empty into Puget Sound near Everett via the Skykomish River and Snohomish River. U.S. Route 2 follows the river's entire length. A BNSF Railway line follows most of the river except near the pass where the tracks use the Cascade Tunnel. Powerlines run by the Bonneville Power Administration (BPA) follow the Tye River west of Tunnel Creek.
Tayport
Tayport lies close to the north east tip of Fife. To the north it looks across the River Tay to Broughty Ferry and Broughty Castle. To the east is the vast Tentsmuir Nature Reserve, an area of forested dunes measuring some 3 km from east to west and 6 km from north to south and edged by wide sands that continue all the way round to the mouth of the River Eden.
Maidenhead Waterways
Running south from the Thames near Cliveden, the channel divides into York Stream - passing under the historic Chapel Arches - and Moor Cut which crosses Town Moor. The channels re-join at Green Lane where they become Bray Cut, before returning to the Thames by Bray Marina. As a side channel of the Thames, the waterway has a perpetual right of public navigation, which cannot be extinguished by lack of use.
Thames Path
The Thames Path's entire length can be walked, and a few parts can be cycled. Some parts of the Thames Path, particularly west of Oxford, are subject to flooding during the winter. The river is also tidal downstream from Teddington Lock and parts of the path may be under water if there is a particularly high tide, although the Thames Barrier protects London from catastrophic flooding. The Thames Path uses the river towpath between Inglesham and Putney. Historically, towpath traffic crossed the river using many ferries, but crossings in these places do not all exist now and some diversion from the towpath is necessary.
The general aim of the path and the object of occasional path changes is to provide walkers with a pleasant route and access to the river, as much as possible.
The Thames Path provision naturally falls into three distinct areas.
Firth of Clyde
The Firth encompasses many islands and peninsulas and has twelve ferry routes connecting them to the mainland and each other. Sometimes called the Clyde Waters, this water body is customarily considered an element of the Irish Sea. The ferry services are run by Caledonian MacBrayne and by Western Ferries and many of the routes are lifeline services for communities living in remote areas. A great number of sea lochs adjoin the Firth, the largest being Loch Fyne.
Kayaking and canoeing on the River Thames
The tidal section is used by sea kayakers and experienced tourers. Above Teddington Lock in London the Thames is freshwater, with levels controlled by a series of weirs which are managed by the Environment Agency.
Dundee
The western and eastern boundaries of the city are marked by two burns that are tributaries of the River Tay. On the western-most boundary of the city, the Lochee burn meets the Fowlis burn, forming the Invergowrie burn, which meets the Tay at Invergowrie basin. The Dighty Water enters Dundee from the village of Strathmartine and marks the boundaries of a number of northern districts of the city, joining the Tay between Barnhill and Monifieth. The Scouring burn in the west end of the city and Dens Burn in the east, both of which played important roles in the industrial development of the city, have now been culverted over.
Tye River (Washington)
The Tye River originates on the west side of the crest of the North Cascades at Stevens Pass. It flows west, then southwest, collecting numerous small tributary streams. At upstream from the Tye's mouth, near the Cascade Tunnel's western portal, Tunnel Creek joins the river. U.S. Route 2 makes a hairpin turn in the valley of Tunnel Creek. The Tye River then turns more directly west. It collects Surprise Creek and its tributary Scenic Creek near Scenic. Deception Creek joins near Deception Falls, above the mouth of the Tye. Scenic, Surprise, and Deception creeks all join from the south. Below Deception Creek the Tye River is joined by Martin Creek from the north. Then, upstream from its mouth, the Tye falls over Alpine Falls. Below the waterfall the Tye River is joined by Carroll Creek and Alpine Creek from the south. The BPA powerline crosses the Tye River above the river's mouth. A couple miles east of Skykomish the Foss River, flowing from the south, joins the Tye River, forming the South Fork Skykomish River.
List of rivers of England
Tees catchment
Eye Water
The stretch of the river from Ayton onward previously had some pollution problems as a quantity of sewage effluent from the village of Ayton and Eymouth contaminated the Water. However, in 2005 Scottish Water completed work which collected the sewage from the villages and pumped it directly to the sewage treatment works at Eyemouth on the coast. At Ayton the Eye Water swings NNE for the final five km leg to its estuary. It runs under the A1 road in a wooded gorge and then receives its largest tributary on its northern bank, the Ale Water which rises on Coldingham Moor 10 km to the NW. The Eye Water enters Eyemouth where it flows on the east side of the harbour, with a stone built quay keeping it separate and forming the river's west bank before the Water eventually enters the harbour lower down near the life boat station.
Taymouth Castle
The castle offers some of Scotland's finest fishing, with two and a half miles of salmon fishing through the estate, on the River Tay. The Tay is the longest river in Scotland and is one of the best rivers in the United Kingdom and Europe for Atlantic Salmon. The estate also has fishing rights on Loch Tay, which contains pike, perch, roach and trout.
Falls of Dochart
Teh waterfalls are situated on the River Dochart at Killin in Stirling (formally in Perthshire), Scotland, near the western end of Loch Tay. The Bridge of Dochart, first constructed in 1760, crosses the river at Killin offering a view of the falls as they cascade over the rocks and around the island of Inchbuie, which is the ancient burial place of the MacNab clan.
Loch Tay
It is a long, narrow loch of around long, and typically around wide, following the line of the strath from the south west to north east. It is the sixth-largest loch in Scotland by area and over deep at its deepest.
Tay River
Tay River may refer to:
Helford River
The area falls into a Special Area of Conservation (Fal and Helford), Site of Special Scientific Interest (Lower Fal & Helford Intertidal) and the Cornwall Area of Outstanding Natural Beauty. The growth of eco and sustainable tourism have seen the development of tourism by Helford River Expeditions focusing on the natural surroundings. The National Trust play an important role with their strategy. Natural England (formerly English Nature) contributes by protecting and monitoring the area. The river is unique in that it is not wholly managed by a specific port or river authority, but brings together major environmental groups and organisations interested in the protection and development of the river. These introduce and recommend safeguards, such as those put forward by Helford River Marine Conservation Group.
Hydrogeology
The Thiem equation is a solution to the steady state groundwater flow equation (Laplace's Equation) for flow to a well. Unless there are large sources of water nearby (a river or lake), true steady-state is rarely achieved in reality.
List of rivers of England
This is a list of rivers of England, organised geographically and taken anti-clockwise around the English coast where the various rivers discharge into the surrounding seas, from the Solway Firth on the Scottish border to the Welsh Dee on the Welsh border, and again from the Wye on the Welsh border anti-clockwise to the Tweed on the Scottish border.
River Fal
Tributaries of the River Fal include the  Truro River, River Kennal,  Penryn River and Carnon River. Several tidal creeks discharge into the River Fal including Mylor Creek, Pill Creek, Penpol Creek and Restronguet Creek. The river flows through the Carrick Roads, a large ria that creates a natural harbour. The waterway is navigable between Falmouth and Truro. The river is crossed by the King Harry Ferry, a vehicular chain ferry that links the villages of Feock and Philleigh approximately equidistant between Truro and Falmouth.
Tay Canal
After the demise of the First Tay Canal, a political lobby started to build a new canal. The Canadian Government had taken over the Tay Navigation Company, and in 1881, they initiated an investigation into making the Tay navigable to Perth. Perth's local member of parliament, John G. Haggart, had some influence in launching this investigation which was carried out by the engineers of the Rideau Canal under the direction of Superintendent Wise. Two routes were examined, one following the route of the First Tay Canal to Port Elmsley and a second involving a canal cut from Beveridge Bay of Lower Rideau Lake to the Tay River.
Thames Path
The Thames Path uses all available riverside rights of way between the traditional source of the river in Trewsbury Mead and Inglesham, but is unable to run alongside the river in several places. The Thames Path starts beside the monument for the source of the river and follows the stream down the hill towards Kemble. On the stretch between Ewen and Somerford Keynes you pass through fields and there are a number of watermills. The path then follows the river through Cotswold Water Park to Ashton Keynes where the river divides into a number of streams; the path partly follows one of these and rejoins the main river by Waterhay Bridge. The path wanders to and from the river amongst more gravel pits until Hailstone Hill, where a branch of the Wilts & Berks Canal formerly crossed the river on an aqueduct. There is a riverside path into and out of (but not within) Cricklade and all the way to Castle Eaton. The path next follows country lanes, a short stretch along a backwater to Hannington Bridge then goes across fields to Inglesham. In 2018 the path incorporated a section of permissive path alongside the river at Upper Inglesham.
Fairy Falls, Trefriw
The Fairy Falls (Welsh: Rhaeadr y Tylwyth Teg) is a waterfall in the village of Trefriw, north Wales.
The falls are on the river Crafnant which has its source at Llyn Crafnant, being joined upstream by a tributary, the river Geirionydd. Below the falls the river Crafnant flows on to itself become a tributary of the river Conwy.
Tay River (Ontario)
The river is in length and drains an area of . A canal connects the river to the Tay Canal, and Rideau Canal systems at Beveridge Bay on Lower Rideau Lake.
Geography of Scotland
Firths of Scotland include the Solway Firth, Firth of Clyde, and Firth of Lorne on the west coast, and the Cromarty Firth, Moray Firth, Firth of Tay, and Firth of Forth on the east coast. The Pentland Firth is not an inlet, but the strait that separates the Orkney Isles from the mainland.
Yai River
The Yai River is a river of Thailand. It is a tributary of the Pa Sak River, part of the Chao Phraya River basin.
River Yeo, Lapford
The River Yeo is a tributary of the River Taw in Devon, England, sometimes known as the Lapford Yeo from the village of Lapford. It is one of several rivers of the same name in Devon, including another tributary of the Taw, the Barnstaple Yeo. The Lapford Yeo flows within 2 miles of the headwaters of another River Yeo, which is a tributary of the River Creedy.
Bala Lake
Llyn Tegid (, ), also known in English as Bala Lake (), is a lake in Gwynedd, Wales. The name Tegid may be related to Welsh "teg", meaning "fair". It was the largest natural body of water in Wales before its level was raised by Thomas Telford to help support the flow of the Ellesmere Canal. It is long by wide. The River Dee runs through it and the waters of the lake are deep and clear. The town of Bala sits at its north-eastern end and the narrow gauge Bala Lake Railway runs for along the lake's south-eastern shore, and continues south-westward to the village of Llanuwchllyn (whose name means "church ['llan'] above ['uwch'] the lake ['llyn']").
Firth of Clyde
The Firth of Clyde is an inlet of the Atlantic Ocean off the southwest coast of Scotland, named for the River Clyde which empties into it. It encloses the largest and deepest coastal waters in the British Isles, sheltered from the Atlantic Ocean by the Kintyre peninsula which encloses the outer firth in Argyll and Ayrshire. The Kilbrannan Sound is a large arm of the Firth of Clyde, separating the Kintyre Peninsula from the Isle of Arran. Within the Firth of Clyde is another major island – the Isle of Bute. Given its strategic location, at the entrance to the middle/upper Clyde, Bute played a vitally important military (naval) role during World War II.
Tay River (Ontario)
The Tay River is a river in Lanark County in Eastern Ontario, Canada. It is in the Saint Lawrence River drainage basin and is a left tributary of the Rideau River.
Stockton-on-Tees
Both the north and south banks of the river are retained by steel sheet pile walls and have footpaths along the river edge. The Tees Walkway on the north bank of the river can be accessed from the town centre by the Teesquay Millennium Footbridge or the Riverside Footbridge and provides a walk along the embankment, as well as a cycle path which forms part of the National Cycle Network. From Castlegate Quay, the tree-lined path along the waterfront toward the Princess of Wales Bridge opens into green space for events and a car parking area. Beyond the Princess of Wales Bridge, the slipway at the River Tees Watersports Centre is situated at the western area of Northshore, which is currently development and leads up to the Tees Barrage.
Wye River (Maryland)
The Wye River is a tributary of the Chesapeake Bay, on the Eastern Shore of Maryland. It was named by the Lloyd family, Edward Lloyd (delegate), and Edward Lloyd (Governor of Maryland), after the River Wye in the United Kingdom. It falls within Queen Anne's County and Talbot County, and joins the Miles River near its mouth to the Eastern Bay. The river is popular with recreational boaters because of its secluded anchorages, fishing, crabbing and proximity to the tourist attractions of St. Michaels, Maryland. Like many rivers on the Chesapeake Bay, the Wye is largely tidal. The river's features include the Wye Island, most of which is part of the Wye Island Natural Resources Management Area, managed by the Maryland Department of Natural Resources State Forest and Park Service. William Paca, the third governor of Maryland and a signatory to the Declaration of Independence, once owned the island.
River Wye
The Environment Agency is the navigation authority for the river. The Normal Tidal Limit (NTL) of the river is Bigsweir and navigation below this point is under the control of the Gloucester Harbour Trustees as Competent Harbour Authority. There is a public right of navigation downstream from Hay-on-Wye. Canoes are generally permitted at and downstream of Glasbury, so long as they do not disturb anglers.
The River Wye provides for canoeing and kayaking as it has sections suitable for all ranges of skills and free access all the way downstream from Hay to Hereford and Monmouth, and the tidal Wye to Chepstow and the Severn Estuary. There are a wide range of canoe hire and supervised trips, as well as campsites at key points on the river. Symonds Yat has a particularly popular series of rapids that was purchased by the British Canoe Union in 2003 to preserve the rapids for recreational use, canoe trips through the rapids stop next at Monmouth. There are three rowing clubs on the river at Hereford, Ross-on-Wye and Monmouth. Annual regattas are held at Ross-on-Wye and Monmouth for rowers and scullers of all abilities, next to the local rowing club.
River Tees
Emerging from the reservoir at Cauldron Snout the river traverses a series of hard black basalt and dolerite rocks that intrude through the softer limestone, in a succession of falls or rapids. From this point downstream the Tees forms the boundary between the traditional counties of Durham and Yorkshire almost without a break, although since 1974 much of it lies wholly in Durham. The dale widens below Cauldron Snout, and trees appear, contrasting with the broken rocks where the water descends over High Force. After a short turn northwards, the river continues to meander south-easterly. Close to where the B6277 road begins to run parallel to the river is the High Force waterfall. About downstream is the smaller Low Force waterfall.
The scenery becomes gentler and more picturesque as the river descends past Middleton-in-Teesdale (Durham). This locality has lead and ironstone resources. Just to the east of Middleton-in-Teesdale, the River Lune joins the Tees. After passing the village of Romaldkirk to the west, the river is joined by the River Balder at Cotherstone. The ancient town of Barnard Castle, Egglestone Abbey, and Rokeby Park, well known through Sir Walter Scott's poem, are all passed. At Rokeby the Tees is joined by the River Greta. From the area near Eggleston, the river is crossing over millstone grit. From here the valley begins to open out, and traverses the rich plain east and south of Darlington in large meandering curves.
Firth
However, some firths are exceptions. The Cromarty Firth on the east coast of Scotland, for example, resembles a large loch with only a relatively small outlet to the sea and the Solway Firth and the Moray Firth are more like extremely large bays. The Pentland Firth is a strait rather than a bay or an inlet.These are connected to, or form part of, the North Sea.
The Northern Isles were part of Norway until the 15th century, and retain many Norse names. In Shetland in particular, "firth" can refer to smaller inlets, although geo, voe and wick are as common. In Orkney, "wick" is common.In the Scottish Gaelic language, "linne" is used to refer to most of the firths above; it is also applied to the Sound of Sleat, Crowlin Sound, Cuillin Sound, Sound of Jura, Sound of Raasay, and part of Loch Linnhe.

Tay Valley, Ontario
Tay Valley is a township in eastern Ontario, Canada, on the Tay River in the southwest corner of Lanark County, adjacent to the United Counties of Leeds and Grenville and Frontenac County. The township administrative offices are located in Glen Tay.
River Yeo, Lapford
The Lapford Yeo rises near South Tawton. It flows north through Bow and Zeal Monachorum to Lapford. It joins the Taw 1.5 miles below Lapford, just below Nymet Bridge. Its largest tributary is the River Dalch, which joins the Yeo near Lapford. The river's catchment area is almost twice the size of the Taw's catchment area above the confluence, but has significantly lower rainfall than the upper Taw valley.
Tay Canal
In 1831, John Jackson, an ex-Sergeant in the army and a miller in Perth was awarded the contract to build the canal. The route would lead from Perth to the mouth of the Tay River. The locks were to be smaller than those on the Rideau, only , and a depth in the channel of . This was a less expensive option and it was felt that it would accommodate most of the commercial traffic of the day. By the end of 1834, five locks, six dams (with timber slides), two swing bridges and several embankments were built. This became known as the First Tay Canal.
Sai River (Thailand)
Sai River (; ; ), formerly known as the River of Lawa (; ), is a river that forms the natural border between Thailand and Myanmar at Tachileik and Mae Sai Districts. Mae Sai town, where the bridge crossing the international border is located, is named after this river. It is a tributary of the Ruak River, itself a tributary of the Mekong.
Stanley, Perthshire
This section of the River Tay is a popular location for canoeing and fishing.
River Ayr
Many practitioners of hillwalking and other related activities are probably aware that the river is pathed for upwards of 90% of its length. Due to disputes with estate owners and weather damage, the walk does temporarily abandon the river in a couple of locations. The path begins in the former village of Glenbuck, now a casualty of opencast mining and general industry decline. It follows the river from its source at Glenbuck Loch and ends at the coastal town of Ayr, where the river empties into the ocean at the Firth of Clyde. Typically the walk is done in 2 or 3 stages.
Hayes River
The Hayes River is a river in Northern Region, Manitoba, Canada that flows from Molson Lake to Hudson Bay at York Factory. It was an historically important river in the development of Canada, and is today a Canadian Heritage River and the longest naturally flowing river in Manitoba.
Firth of Tay
The Firth of Tay and Eden Estuary were designated a Ramsar sites on 28 July 2000, as a Special Protection Area on 2 February 2000 and as a Special Area of Conservation on 17 March 2005. Several parts are within a site of special scientific interest - Inner Tay Estuary, Monifieth Bay, Tayport-Tentsmuir Coast. The Invergowrie Bay section is a local nature reserve.
Taymouth Castle
Taymouth Castle is situated to the north-east of the village of Kenmore, Perth and Kinross in the Highlands of Scotland, in an estate which encompasses 450 acres. It lies on the south bank of the River Tay, about a mile from Loch Tay, in the heartland of the Grampian Mountains. Taymouth is bordered on two sides by mountain ranges, by Loch Tay on the third and by the confluence of the rivers Lyon and Tay on the fourth.
River Garry, Perthshire
The River Garry () is a major tributary of the River Tummel, itself a tributary of the River Tay, in the traditional county of Perthshire in the Scottish Highlands. It emerges from the northeastern end of Loch Garry just to the southeast of the Pass of Drumochter, and flows southeastwards and eastwards down Glen Garry to the narrow Pass of Killiecrankie beyond which it joins the Tummel
Stockton-on-Tees
Downstream on the River Tees is Portrack Marsh Nature Reserve, a nature reserve by the northern bank of the river between the Tees Barrage and the Tees Viaduct near Portrack housing estate. It is the last remaining wetland on the lower Tees. Ownership of the reserve is split between Tees Valley Wildlife Trust and Northumbrian Water, but the reserve is managed by Tees Valley Wildlife Trust. The west and north part of the reserve is mature marsh while there are a series of man – made ponds in the remainder.
Tees Barrage
The Tees Barrage is a barrage across the River Tees just upriver of Blue House Point in the borough of Stockton-on-Tees in North East of England and is used to control the flow of the river, preventing flooding and the effects of tidal change.
The Tees Barrage comprises a river barrage, road bridge, footbridge, barge lock, fish pass and white water course.
The waters above the barrage are permanently held at the level of an average high tide and are used for watersports such as canoeing, jet skiing, dragonboat racing and incorporates a 1 km rowing course.
The barrage is accessible by road only from Thornaby-on-Tees as there is very limited road access to the north bank of the Tees.
Afon Pyrddin
The Afon Pyrddin is a river forming a short section of the boundary between the county of Powys and Neath Port Talbot in Wales, Great Britain. It also forms a part of the boundary of the Brecon Beacons National Park. The river and its waterfalls are one of the key attractions of the Fforest Fawr Geopark designated in 2005.
River Tay
In the 19th century the Tay Rail Bridge was built across the firth at Dundee as part of the East Coast Main Line, which linked Aberdeen in the north with Edinburgh and London to the south. The bridge, designed by Sir Thomas Bouch, officially opened in May 1878. On 28 December 1879 the bridge collapsed as a train passed over. The entire train fell into the firth, with the loss of 75 passengers and train crew. The event was commemorated in a poem, The Tay Bridge Disaster (1880), written by William McGonagall, a notoriously unskilled Scottish poet. The critical response to his article was enhanced as he had previously written two poems celebrating the strength and certain immortality of the Tay Bridge. A second much more well received poem was published in the same year by the German writer Theodor Fontane. A. J. Cronin's first novel, "Hatter's Castle" (1931), includes a scene involving the Tay Bridge Disaster, and the 1942 filmed version of the book recreates the bridge's catastrophic collapse. The rail bridge was rebuilt, with the replacement bridge opening on 11 June 1887.
River Tay
The River Tay () is the longest river in Scotland and the seventh-longest in the United Kingdom. The Tay originates in western Scotland on the slopes of Ben Lui (), then flows easterly across the Highlands, through Loch Dochart, Loch Iubhair and Loch Tay, then continues east through Strathtay (see Strath), in the centre of Scotland, then southeasterly through Perth, where it becomes tidal, to its mouth at the Firth of Tay, south of Dundee. It is the largest river in the UK by measured discharge. Its catchment is approximately , the Tweed's is and the Spey's is .
Fly River
Both the Strickland and the Ok Tedi Rivers have been the source of environmental controversy due to tailings waste from the Porgera Mine and the Ok Tedi Mine, respectively. Sediment sampling and coring in the distributary channels of the Fly Delta had not detected copper concentrations significantly higher than background as of 1994. In 2008, Dr Ian Campbell, a former advisor to Ok Tedi Mining Limited, claimed that company data suggest significant portions of the Fly River floodplain are at a high risk from acid mine drainage.
Loch Tay
Killin at the head of the loch, and Kenmore at the outflow of the River Tay, are the main settlements on the lochside today. The smaller settlements of Acharn, Ardeonaig and Ardtalnaig are located on the south side of the loch whilst Fearnan and Lawers are on the north side. The loch is fed by the rivers Dochart and Lochay at its head and numerous smaller streams.
River Tas
Tributaries which have their sources at Hempnall and Carleton Rode converge at Tasburgh. The river then flows on through Newton Flotman and Smockmill Common. In Shotesham Park the river splits into two channels which rejoin just above Shotesham ford. The pool here is a popular location in summer time for paddling, swimming and fishing. From Shotesham the river flows northwards through Stoke Holy Cross, Dunston, Caistor St Edmund, Markshall and Arminghall. It joins the River Yare at Trowse - just south of Norwich.
River Fowey
The river runs through two Sites of Special Scientific Interest (SSSI), one of which is also part of a National Nature Reserve (NNR). 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 (pronounced "Goleetha") 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
Firth of Tay
At some 15 km in length, the reedbed on the north shore of the inner estuary is thought to be the most extensive in Britain.
Tay, Ontario
Tay is a township in Central Ontario, Canada, located in Simcoe County in the southern Georgian Bay region. The township was named in 1822 after a pet dog of Lady Sarah Maitland (1792–1873), wife of Sir Peregrine Maitland, Lieutenant Governor of Upper Canada. Two other adjoining townships were also named for her pet dogs, Tiny and Flos (now Springwater Township).
