Jaasjärvi

Jääsjärvi is a lake in the Finnish interior whose name means “ice lake.” Its clear waters contain dozens of islands, among them Vehkasalo, Hirtesalo and Ohrasaari. The Tainionvirta flows out of the lake and passes through smaller lakes on its way to Päijänne, joining Jääsjärvi to the wider waters of the Kymijoki basin. In winter the lake usually freezes, changing the character of its many shores and channels.
