The New River is a man made waterway in England, opened in 1613 to supply London with fresh drinking water. It starts in between Ware and Hertford in Hertfordshire and travels 20 miles down to Stoke Newington. Among the districts it flows through are: Islington
Originally the course was above ground throughout, but more recently some sections have been put underground, enabling the course to be straightened. The New River is still an important link in the supply of water to London.
