The Great Prespa Lake is shared between Albania in the west, North Macedonia in the northeast and Greece to the southeast. Slightly to the south, the Small Prespa Lake extends between Albania and Greece and drains into the Great Prespa, which is separated through a narrow path from it. The lakes are situated between 849 and 853 metres elevation above the Adriatic, being the highest tectonic lakes in Southeastern Europe. The Great Prespa is primarily fed by underground tributaries and streams and emerge into the Lake Ohrid. The lakes are surrounded by high mountains including Mali i Thatë in Albania and Galičica in North Macedonia. Between the mountains in the west, there is a narrow outlet of which the lake drains during floods of heavy rainfall and in spring during the snow melt to the Devoll River, which flows through the central mountain range of Albania until it discharges into the Adriatic Sea on the Mediterranean Sea.
