The lake Synevyr spilled at an altitude of almost 1000 meters above sea level.
It was formed, as a result of an earthquake, about 10 thousand years ago.
A powerful displacement generated the natural dam, which became an insurmountable obstacle for the mountain streams.
And the hollow was filled with water.
Nowadays the lake consists of two parts: the deepest northern and shallow southern.
Divides their underwater ridge.
Synevir is the largest lake in the Ukrainian Carpathians.
Its average area is 5 hectares, and the largest depth is 22 meters.
