Lake Bokodi, in the village of Bokod, about 80 kilometers west of Budapest, Hungary, is an artificial lake created in 1961 by the Oroszlány Thermal Power Company by flooding a low-lying meadow next to the plant. The power plant draws cold water from the lake to operate its boilers, and warm water is returned back to the lake. This continues recycling of the water causes the lake to never freeze even in the chilly winter air.
