Vanhankaupunginkoski rapids of Vantaanjoki in Helsinki |
The Vantaanjoki ( Swedish Vanda å ) is a 99 km long river in southern Finland . It rises in Lake Erkylänjärvi in the municipality of Hausjärvi and flows into the Gulf of Finland near Helsinki .
After its source at Hausjärvi, the Vantaanjoki first flows to the northwest through the town of Riihimäki , where it makes an arc and from now on flows south. Next, it crosses Hyvinkää , Nurmijärvi and Vantaa , before flowing into the Vanhankaupunginlahti bay in northeast Helsinki.
The size of the catchment area of the Vantaanjoki is 1,685 km². The river has several rapids, the largest of which is Vantaankoski with a length of 240 m and a height of 5 m. The longest tributary of the Vantaanjoki is the Keravanjoki . Most of the Vantaanjoki river valley is used for agriculture. Until the completion of the Päijänne tunnel in 1982, Helsinki's drinking water was taken from Vantaanjoki.
The river was named after the Vanantaa manor near Janakkala . The name of the estate means something like “behind Vanaja”, ie “beyond Lake Vanajavesi ”. The city of Vantaa, a suburb of Helsinki on the lower reaches of the river, got its name in 1972 after the river, before it was known as the “Helsinki rural community”.
The mouth of the Vantaanjoki is located in the Helsinki suburb of Vanhakaupunki . Helsinki was founded here in 1550 under the Swedish name Helsingfors, and it was not until 1640 that the city was moved to its current location further south. The name Helsingfors derives from a rapids (Swedish fors ) of the Vantaanjoki, which at that time was called Helsinge å (Finnish Helsinginjoki ) on its lower reaches .
