Whiteadder Water

Whiteadder Water /ˈhwʌtədər/[1] is a river in East Lothian and Berwickshire, Scotland. It also flows for a very short distance through Northumberland before joining the River Tweed. In common with the adwaters of the Biel Water it rises on the low hillside of Clints Dod (122 m or 400 ft) in the Lammermuir Hills, just ESE of Whitecastle Hillfort and 3 km (1.9 mi) south-east of the village of Garvald.

Adder may be derived from Brittonic *ador, *edir or Old English edre,[2] possible ancient hydronymic terms derived from an Indo-European formation meaning "a watercourse, a channel" (compare River Etherow).[2] The possibility of the name deriving from Old English ǣdre, "a vein" (Anglian ēdre),[2] or *ǣdre, meaning "quickly" is objected on the grounds that these would have maintained the long initial vowel in English and Scots.[2]

Also suggested is derivation from Gaelic fad dûr,[3] meaning "long water".[3]


The stream wends its way south east for approximately 5 km (3.1 mi) where it joins with the Faseny Water to form the Whiteadder Reservoir created in 1968, which supplies most of the towns of East Lothian (including Cockenzie power station) and Berwickshire, with water.

From there, crossing into Berwickshire it runs alongside the B6355 road to Ellemford where it joins the Dye Water and further on at Abbey St. Bathans, the Monynut Water.

By this point having become a much larger body of flow, the Whiteadder meanders across Eastern parts of the Merse passing the communities of Preston, Chirnside, Allanton. Here at Allanton the Whiteadder joins with its antonymic counterpart the Blackadder Water. The river proceeds by Foulden, Edrington, and Paxton, it crosses into England, before joining the River Tweed, just north of East Ord, a suburb of Berwick-upon-Tweed.


For those with fishing permits, the Whiteadder provides recreational salmon and trout fishing. It is also the site of Ninewells, the childhood home of David Hume.[4]

The lowermost section of the Whiteadder is a Site of Special Scientific Interest (SSSI) by virtue of its Water Crowfoot, Salmon, Lamprey and moulting Mute Swan.
