Aura River
From Wikipedia, the free encyclopedia
The Aura River (Finnish Aurajoki; Swedish Aura å) is a river in south-western Finland. Its sources are in the town of Oripää, and it flows through Pöytyä, Aura and Lieto before discharging into the Archipelago Sea in the middle of the city of Turku. The total length of the river is about 70 km (44 mi), and it contains eleven rapids, the biggest of which is Nautelankoski at Lieto. The tap water for Turku is drawn from the Aura river, the city waterworks being situated by the Halinen rapids.
The word "Aura" appears to come from an archaic Swedish word for waterway, but it now translates as "plow," a name the river lives up to. Situated in an agricultural zone, it's turbidied by surface runoff from nearby farms with eutrophication as the biggest threat. Its condition has been improving since the 1970s and the Aura river is now clean enough to support salmon.
The banks of the river have been inhabited on locations at least 6000 years ago. It is notable for the cultural heritage in Finland. The archdiocese of Finland has been situated near the river since the thirteenth century.
