Lake Orivesi

Orivesi is one of the great basins of the Saimaa lake system in eastern Finland. Numerous islands divide its waters into broad reaches; the southern reach, Paasselkä, occupies an ancient impact crater. Its outlet, the Orivirta, leads towards Pyyvesi. Both names contain the Finnish word for a stallion, although it is uncertain which was named first. The lake belongs to the intricate inland waters of Karelia and Savo, where channels link one broad basin to another.
