The '''River Clyde''' is the most important river on the west coast of [[Scotland]]. From its source in the Lowther hills in the [[Scottish Lowlands]], it runs down Clydesdale (from where comes the Clydesdale breed of large [[horse]]), past [[Lanark]], [[Motherwell]] and [[Hamilton]], through [[Glasgow]] and out into the [[Firth of Clyde]] at [[Gourock]].

The '''River Clyde''', is the most important river in western-[[Scotland]] and, at 158km (99 miles) long, is the second longest river (after the Tay) in [[Scotland]]. It is formed (at the aptly named Meetwater) by the confluence of Daer Water and Potrail Water in the Lowther Hills of [[Lanarkshire]] near the sources of both the [[River Tweed|Tweed]] and River Annan. It wanders off to the north-east as far as Biggar before heading more or less north-west past Lanark, [[Clydesdale]], [[Glasgow]] and [[Clydesbank]] then enters the [[Firth of Clyde]] near [[Dumbarton]].

(The Old Celtic name, possibly meaning “cleanse”, may have derived from the [[Indo-European]] ''clou'', and was also possibly the name of a river goddess. The [[Roman]] historian [[Tacitus]] refers to it as the ''Clota''. It became the Gaelic ''Clutha''. Today it is the ''Cluaidh''.)

Large scale dredging in the 18th century brought ocean-going vessels to Glasgow, and made the river a conduit for much the industrial produce of south-western Scotland on its way to the New World, and the city a site of a booming ship-building industry.
