tekojärvi

Tekojärvi is a Finnish word that translates to "artificial lake" or "reservoir". It refers to a man-made body of water created by damming a river or stream. These reservoirs are typically constructed for a variety of purposes, including hydroelectric power generation, flood control, water supply for agriculture and industry, and recreational activities.

The formation of a tekojärvi involves significant engineering efforts. A dam is built across a natural watercourse, causing water to back up and form a lake behind it. The size and depth of a tekojärvi depend on the scale of the dam and the topography of the surrounding area. The creation of such a lake can alter the local ecosystem, impacting fish populations, vegetation, and water quality.

Finland, with its numerous waterways and historical reliance on hydropower, has many tekojärvi. These artificial lakes play an important role in the country's energy production and water management strategies. While beneficial for their intended purposes, the environmental and social impacts of their construction are often carefully considered and managed. Examples of tekojärvi can be found across Finland, contributing to the nation's infrastructure and landscape.
