Kemijoki

Kemijoki is the longest river in Finland, flowing through the northern part of the country. It originates in the municipalities of Salla and Savukoski in Lapland and travels approximately 550 kilometers before emptying into the Gulf of Bothnia. The river's watershed covers a significant area of Lapland, characterized by vast forests, fells, and numerous lakes.

Historically, Kemijoki has been vital for transportation and timber floating. In the 20th century, its potential for hydroelectric power generation was recognized and extensively developed. The Kemijoki Oy company was established to manage the river's hydropower resources, leading to the construction of numerous dams and power plants along its course. These dams have significantly altered the river's natural flow and landscape, creating large reservoirs.

The regulation of Kemijoki has had ecological impacts, affecting fish populations and riparian ecosystems. Despite these changes, the river remains an important natural feature in Lapland, supporting a unique subarctic environment. The landscape around Kemijoki is popular for outdoor activities such as fishing, boating, and hiking, particularly during the summer months. The river's journey through sparsely populated areas offers a glimpse into the wild beauty of Finnish Lapland.
