The Tammerkoski Falls or Rapids are located in the town of Tampere.
The Tammerkoski rapids came into being 7'500 years ago when the waters of the lake Näsijärvi broke through the lowest point of the Pyynikinharju ridge, formed in the Ice Age, to make an outlet into lake Pyhäjärvi. The rapids are about one kilometre in length, with a drop of 18 metres between the two lakes.
Today, there are currently four power stations and three dams located on the Tammerkoski.
