Kemijoki River
The Kemijoki is Finland's longest river, stretching approximately 550 kilometers, and is a vital artery for the country's energy production. Originating near the Russian border in Savukoski, it flows through the vast landscapes of Lapland before emptying into the Gulf of Bothnia at Kemi. The river is highly regulated by 21 hydroelectric power plants, which together produce about one-third of Finland's hydroelectricity. Before the construction of these power plants in the mid-20th century, the Kemijoki was one of Europe's most significant salmon rivers, but fish migration routes were disrupted by the dams. Today, major efforts are underway to maintain fish populations through breeding programs and fish ladders. The Kemijoki passes through major towns like Rovaniemi, where it joins the Ounasjoki River. Historically, the river served as a crucial transport route for timber rafting. The extensive floodplains and surrounding arctic nature make it a vital ecosystem for numerous bird species and aquatic life. Despite industrial utilization, the Kemijoki remains a symbol of the untamed power of northern waters.
