Abstract: 

Ohrid Lake is situated in the south-eastern part of Albania, at the border area between Albania and Macedonia. This boundary goes through the lake in a NW-SE direction. It has a considerable depth (295 m), thus being the deepest lake of the Balkan Peninsula. Regarding to geological formations, the Lake mainly lies above ultrabasic rocks of the Shebeniku ophiolitic massif and carbonatic rocks of Late Triassic - Late Jurassic age.
   In the southeastern part of the lake, localized into Upper Triassic limestones, there is a dense network of underground springs. One of the greatest river in Albania, Drini i Zi, springs from the Ohrid Lake, too. But on the other hand, groundwater supply has a predominant role. Thus, a natural equilibrium exists in its hydrodynamic regime.
   Except for the beautiful view of the lake, the interesting geomorphological situation dominating over the lake and on its bottom should be emphasized. In recent times, the landscape around the lake and above all, the lake water, has been threatened by different factors resulting in their pollution and destruction.
   Besides the lake, in the area over it there are several interesting geological sites.
