The Colne is a river in England which is a tributary of the River Thames. Just over half its course is in south Hertfordshire. Downstream, the Colne is the boundary between Buckinghamshire (specifically the South Bucks district) and London (specifically the London Borough of Hillingdon) and finally between corners of Berkshire and Surrey. On leaving Hertfordshire, the watercourse splits off into several separate branches, a few of which rejoin it, and its main branch flows into the River Thames on the reach above Penton Hook Lock at Staines-upon-Thames.

  • The Colne is a river in England which is a tributary of the River Thames. Just over half its course is in south Hertfordshire. Downstream, the Colne is the boundary between Buckinghamshire (specifically the South Bucks district) and London (specifically the London Borough of Hillingdon) and finally between corners of Berkshire and Surrey. On leaving Hertfordshire, the watercourse splits off into several separate branches, a few of which rejoin it, and its main branch flows into the River Thames on the reach above Penton Hook Lock at Staines-upon-Thames. Two further, artificial distributaries were constructed in the 1600-1750 period for aesthetic reasons for Hampton Court and for Syon Park which have been kept maintained, flowing through several London districts. Although their main purpose was not drinking water, these artificial streams can be likened to the New River in scale and in date. Crossing its route, viaducts and canals, such as the Grand Union Canal have been recognised for pioneering engineering during the Industrial Revolution. Digging for gravel and clay along its lower course south of Rickmansworth has created a long belt of pits which have flooded to become lakes. Many of these are important habitats for wildlife and protected as nature reserves. The river, meadows and many once gravel-producing lakes form the Colne Valley regional park in total covering 43 square miles (110 km2). (en)
  • Der River Colne ist ein Wasserlauf in England. Er entsteht in Hertfordshire westlich von Welham Green. Er fließt zunächst in nördlicher Richtung, wendet sich bei Colney Heath jedoch in eine südwestliche Richtung. Er fließt durch Watford und im Südwesten von Rickmansworth wendet er sich nach Süden. Sein Lauf bildet dabei zunächst streckenweise die Grenze von Hertfordshire und Greater London und dann streckenweise die Grenze von Greater London und Buckinghamshire. Er überquert die Grenze zu Surrey an der südwestlichen Ecke des Flughafens Heathrow in dessen Westen er fließt und mündet in Staines in die Themse. Der Lauf des Colne ist von zahlreichen Nebenarmen und verschiedenen Abflüsse gekennzeichnet. Zu diesen gehören: * River Ash (Abfluss) * Colne Brook (Abfluss) * Longford River (Abfluss) * Duke of Northumberland’s River (Abfluss) * Fray’s River (Nebenarm) * Wraysbury River (Nebenarm) (de)
  • De Colne is een zijrivier van de Theems en loopt langs de westkant van Londen. De rivier loopt door onder meer Watford, Staines, Uxbridge en West Drayton. De Colne stroomt voornamelijk door Hertfordshire en vormt de grens tussen het district South Bucks van Buckinghamshire en Hillingdon, het westelijkst gelegen borough van Groot-Londen. De bron van de Colne is bij het dorpje North Mymms in Hertfordshire, ten noordwesten van Londen. Van hieruit loopt de rivier naar Watford en verder naar Uxbridge. Het loopt hierna parallel aan het Grand Union Canal. De Colne stroomt de Theems in bij de sluis Penton Hook Lock in Laleham (Surrey), vlak bij Staines. De Frays is een zijtak van de Colne die zich bij Uxbridge afsplitst van de Colne en zich bij West Drayton weer bij de Colne voegt. Enkele andere zijrivieren van de Colne zijn de Ver, de Colne Brook, de Wraysbury (die zich bij Staines weer bij de Colne voegt) en de Duke of Northumberland's River, eigenlijk een 16e-eeuws kanaal. Plaatsen vernoemd naar de rivier zijn London Colney, Colney Heath en Colney Street in Hertfordshire. Colnbrook in Berkshire is vernoemd naar de zijrivier Colne Brook.
