River Wey

The river is first recorded as Waie in the year 675. The meaning and origin of its name is an unclear one, yet is most likely derived from a Proto-Indo-European (in other words, pre-Iron Age) word uegh or weg meaning water or running water.Ekwall, E. (1928) English River-Names. Oxford University Press, p. 454Coates, R. (1989) The place-names of Hampshire. Batsford, p. 174

The Wey north branch, sometimes referred to as the Alton Wey, has its official nomenclature source in Alton in Hampshire; however is exceeded by length and, in wet weather, in flow by the nearby Caker Stream rising in dendritic drainage spanning fields of Upper Farringdon and Hartley Mauditt, passing Chawton between these places. After the union in Alton the brook runs quite straight, east north-east through Upper Froyle and Bentley, turning southeast after Farnham's centre to Tilford.{{Cite web |url=http://www.weyriver.co.uk/theriver |title=The River Wey and Wey Navigations Community Site |access-date=27 June 2008 |archive-date=25 June 2008 |archive-url=https://web.archive.org/web/20080625040403/http://www.weyriver.co.uk/theriver/ |url-status=live }}

The steep-sided valley accentuates entering Surrey, between vast masses termed the Lower Greensand Group (south), then down the more easterly valley on both sides (east and west). Reflecting the crumbly nature of this material which has readily eroded, the valley falls from about {{convert|230|ft}} entering Surrey {{convert|1.5|mi}} west of Farnham to {{convert|60|ft}} lower at Tilford {{convert|4|mi}} south-east of Farnham and changes from almost v-shaped to a more u-shaped alluvial plain.

The upper parts of the branch were the start of the upper River Blackwater's catchment.{{cite journal |vauthors= Linton DL |year= 1930 |title= The development of the Wey drainage system |journal= Proc.

The source rocks of the gravels prove the former extent of the river. Great erosion has occurred in the Wey down to Tilford, along the sinuous, multiple-anabranch Waverley Abbey stretch, through, what Blyth notes as, the "soft strata", of that landscape.

The Wey South branch stems from two main westward brooks, one now followed by the Portsmouth Direct Line,{{#tag:ref|The branch of east Shottermill, Haslemere|group= n}} the other – with longer source brooks – following the Surrey/Sussex boundary,{{#tag:ref|The branch of Camelsdale, Haslemere|group= n}} which combine at a point, heading west, where the line first comes as close as 97 metres to the boundary – in the east end of a park, next to one of its three river footbridges. These brooks are fed by six main streams. The farthest are the southern streams. These drain parallel, north, narrow vales between the northerly "fingers" or "ribs" of:

• Blackdown, the third-highest hill in Southeastern England
• Ridge Hill
• Fridays Hill
• Marley Heights (formerly Moseshill), called Marley Common

The northern streams drain fingers of a single east–west ridge of Greensand, their common names, again from east to west, are:

The Wey drains and passes Haslemere's western suburbs then Liphook, Bramshott (including Passfield), Standford and Lindford, and the large parish of Frensham. It combines with the north branch at Tilford, in which parish all three flows have large meanders.

Notable tributaries of the south branch are Cooper's Stream and the River Slea.

From Tilford, the river runs through Elstead, Eashing, Godalming, Peasmarsh/Shalford, Guildford, Send, Old Woking, Pyrford, Byfleet, New Haw and forms the historically much more meandering border between Addlestone/Weybridge, today doing so most accurately between Hamm Court and Whittet's Ait respectively.[https://www.achurchnearyou.com/search/?lat=51.38&lon=-0.45 Church of England] {{Webarchive|url=https://web.archive.org/web/20210123093801/https://www.achurchnearyou.com/search/?lat=51.38&lon=-0.45 |date=23 January 2021 }} current ecclesiastical parish boundaries[https://www.visionofbritain.org.uk/unit/10147621/boundary old parish boundary approximate maps] {{Webarchive|url=https://web.archive.org/web/20210123093802/https://www.visionofbritain.org.uk/unit/10147621/boundary |date=23 January 2021 }} Vision of Britain: History of Parliament Trust; University of Portsmouth and Others.{{Cite web |url=https://www.richmondandtwickenhamtimes.co.uk/news/119186.council-to-take-over-land/ |title=Council to Take over Land | Richmond and Twickenham Times |access-date=23 June 2020 |archive-date=24 June 2020 |archive-url=https://web.archive.org/web/20200624024758/https://www.richmondandtwickenhamtimes.co.uk/news/119186.council-to-take-over-land/ |url-status=live }} From Godalming the river is intertwined with the Wey and Godalming Navigations. The {{convert|20|mi}} of the navigations' towpath is open to pedestrians. The river joins the Thames at a cascading channel off its Navigation Canal (above Thames Lock) between Hamm Court and Whittet's Ait and a weir-fed navigation east of the ait facing the main weir stream of Shepperton Lock.

The River Ock joins at Godalming, Cranleigh Waters and the River Tillingbourne at Shalford and the Hoe Stream at Woking.

The river has long been used as a source of power for mills, and many are recorded in the Domesday Book. Between the 17th and 19th centuries there were over 40 mills on the river and more on its tributaries. At various times they have been used for grinding grain, fulling wool, rolling oats, crushing cattle cake, leather dressing, paper production and gunpowder manufacture. Willey Mill, at Farnham, was still in use in 1953.{{cite web | title=All About Watermills & Their Millers | work=The River Wey & Navigations website | url=http://www.weyriver.co.uk/theriver/industry_2_watermills.htm | access-date=23 October 2007 | archive-date=6 August 2018 | archive-url=https://web.archive.org/web/20180806174820/http://www.weyriver.co.uk/theriver/industry_2_watermills.htm | url-status=live }} Headley Mill is still in commercial operation. {{cite web |title=Headley Mill |url=https://www.hampshiremills.org/Mills%20Headley.htm |website=Hampshire Mills Group |access-date=2 August 2019 |archive-date=19 January 2019 |archive-url=https://web.archive.org/web/20190119161522/http://www.hampshiremills.org/Mills%20Headley.htm |url-status=live }} Guildford Town Mill, though no longer used for milling, still harnesses the power of the river to generate electricity.

During the seventeenth century, the river was made navigable to Guildford and extended in the eighteenth century to Godalming. The Basingstoke Canal and Wey and Arun Junction Canal were later connected to the river. The navigable sections are now owned by the National Trust.

Wey Valley is a term for the narrowing basin of the River Wey before it empties into the River Thames.

Much of the upper reaches of the river are within the Surrey Hills Area of Outstanding Natural Beauty. The river passes through a variety of habitats including heathland, woodland and watermeadow, resulting in a diversity of wildlife. There are Sites of Special Scientific Interest (SSSI) and Nature Reserves along the river.

A broad basin of aquifers drain steeply to the river so, as with the Mole, in its natural state, much of the flood plains were prone to regular flooding. This has been greatly reduced by flood alleviation measures, upstream lakes such as Frensham Great Pond and, inadvertently, the Wey navigations. The lowest urban areas of Godalming, Byfleet and Weybridge saw extensive flooding in the exceptional winter storms of 2013–14.[http://www.getsurrey.co.uk/news/local-news/recap-flood-hit-communities-prepare-further-6698464 Recap: Flood-hit communities prepare for further rainfall] {{Webarchive|url=https://web.archive.org/web/20140418222059/http://www.getsurrey.co.uk/news/local-news/recap-flood-hit-communities-prepare-further-6698464 |date=18 April 2014 }} Surrey Advertiser Group. 12 February 2014.

The Environment Agency measure water quality of the river systems in England. Each is given an overall ecological status, which may be one of five levels: high, good, moderate, poor and bad. There are several components that are used to determine this, including biological status, which looks at the quantity and varieties of invertebrates, angiosperms and fish. Chemical status, which compares the concentrations of various chemicals against known safe concentrations, is rated good or fail.{{cite web |url=http://environment.data.gov.uk/catchment-planning/help/glossary |website=Catchment Data Explorer |title=Glossary (see Biological quality element; Chemical status; and Ecological status) |publisher=Environment Agency |date=17 February 2016 |access-date=25 July 2020 |archive-date=2 October 2020 |archive-url=https://web.archive.org/web/20201002010119/http://environment.data.gov.uk/catchment-planning/glossary |url-status=live }} 30px Text was copied from this source, which is available under an [http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ Open Government Licence v3.0]. © Crown copyright.
