Finnish Lakeland

The Finnish Lakeland is a massive landscape region located in central and eastern Finland.

This area is characterized by a hilly, forest-covered plateau. It is a vast network of water and land that spans approximately 370 kilometers from south to north. It also reaches about 350 kilometers from east to west. To the south, the region is bounded by the Salpausselkä Ridges. These ridges are terminal moraines, which are accumulations of debris left by a glacier. To the north, the district meets Upland Finland. To the west and northwest, it transitions into the Coastal Finland district. The lake landscape even extends eastward into Russia, covering the Karelian Isthmus and the Republic of Karelia.

The unique shape of this land is a result of ancient glacial activity. About 10,000 years ago, continental glaciers receded from the country. These massive ice sheets scoured and gouged the surface of the land. They left behind specific glacial remnants known as drumlins and long, sinuous eskers. Drumlins are streamlined hills, while eskers are long, winding ridges of sediment. Additionally, the lake basins themselves formed through a combination of weathering and erosion. This erosion occurred within fractures in the bedrock both before and during the Quaternary ice ages. This process of erosion along fractures created the linear inlets seen among the lakes today.

Water is a defining feature of this region, covering about 25% of the total area.

Because there is no single official way to count lakes, exact numbers are difficult to determine. However, scientists identify at least 55,000 lakes that are at least 200 meters wide. If a lake is defined as any body of standing water larger than 500 square meters, Finland contains 187,888 lakes. In the Lakeland district, there is an average of 40 lakes per 100 square kilometers. The density of lakes is highest north of Lake Inari. In that area, there can be as many as 1,000 lakes per 100 square kilometers. Because of this high density, the area is sometimes called Lampi-Suomi, or Pond Finland.

The lakes in this region often have extremely convoluted coastlines. They frequently consist of several stretches of open water, known as a selkä, connected by narrow sounds. These connections allow the lakes to link large areas of land and their hinterlands together. While the landscape is water-rich, much of the territory remains heavily forested. This results in a relatively low population density across the district.

Many people use the water for recreation, such as building summer cottages, or mökki, on various islands.

Lake Saimaa is the largest lake within the Finnish Lakeland. It has a surface area exceeding 4,400 square kilometers. This makes it the fourth largest natural freshwater lake in all of Europe.

The Saimaa region is incredibly complex, containing 5,484 islands within the lake itself. If you count all the islands in the greater Saimaa region, the number reaches up to 13,710. The Saimaa Canal provides a vital connection from Lake Saimaa to the Vyborg Bay in the Gulf of Finland, which is part of the Baltic Sea. Another route to the Baltic Sea involves the Vuoksi River. This river flows from Saimaa to Lake Ladoga, and then through the Neva River into the Gulf of Finland.

Another major body of water is Lake Päijänne, which is the second-largest lake in Finland.

This lake is essential for human use, as it serves as a drinking water supply for the city of Helsinki. It drains into the Gulf of Finland via the Kymi River. While Lake Päijänne is significant, it is not the deepest lake in the region. Its maximum depth is only 95.3 meters. In comparison, the average depth for lakes in this area is only about 7 meters.

Human settlement in the Lakeland has historically been shaped by these water systems. In earlier times, the lakes served as the primary transport routes for moving people and goods. As a result, many major urban areas are located directly on the lakeshores. Some cities are even built on isthmuses or peninsulas. Notable cities in the region include Imatra, Joensuu, Jyväskylä, Kuopio, Lappeenranta, Mikkeli, Pieksämäki, Savonlinna, and Varkaus. These locations allow the population to stay connected to the vast aquatic network that defines their home.
