<P> The River Spey (Scottish Gaelic: Uisge Spè) is a river in the northeast of Scotland . It is the ninth longest river in the United Kingdom, as well as the third longest and fastest - flowing river in Scotland . It is important for salmon fishing and whisky production . </P> <P> The origins of its name are unclear though' hawthorn river' has been suggested (from a word linked to the Brythonic * yspyddad) as has a derivation from the pre-Celtic * squeas meaning' vomit' or' gush' . Ptolemy named the river on his map of c. 150 as Tuesis . The name' Spey' first appears in 1451 . </P> <P> The Spey is 107 miles (172 km) long . It rises at over 1,000 feet (300 m) at Loch Spey in Corrieyairack Forest in the Scottish Highlands, 10 miles (16 km) south of Fort Augustus . The river descends through Newtonmore and Kingussie, crossing Loch Insh before reaching Aviemore, giving its name to Strathspey . From there it flows the remaining 60 miles (97 km) north - east to the Moray Firth, reaching the sea 5 miles (8 km) west of Buckie . </P> <P> On some sections of its course, the Spey changes course frequently, either gradually as a result of deposition and erosion from normal flow, or in a matter of hours as a result of spate . The Spey spates quickly due to its wide mountainous catchment area as a result of rainfall or snow - melt . </P>
