Oulujoki River

Oulujoki River is a river in Finland's Oulu province. Its name translates to "Oulu River" (Swedish: Ule älv) in Finnish, and originally meant "Flood River" in ancient Northern Ostrobothnian dialect. Its source is Oulujärvi, and its watershed area encompasses a large portion of the Kainuu region.

At Oulu, it empties into the Bothnian Bay. The port of Oulu is located near the river's mouth. The Oulujoki River is one of Finland's major rivers. It begins in Lake Oulujärvi and travels over 100 kilometers to Oulu and the Gulf of Bothnia, passing through Muhos. For thousands of years, the Oulujoki river has served as a vital trading and transportation route for the inhabitants of the area.

Oulujoki River is also the most well-known route for delivering tar in Finland and Europe. Today, the river generates enormous amounts of hydroelectric electricity on a national scale, as well as enough fish to meet fishing demands. Because of its nutrient-rich soil and favorable microclimate, the river valley is also an important agricultural area. The Oulujoki river is fed by several tributaries, the largest of which are the Kutujoki, Utosjoki, and Muhosjoki rivers.
