The Lake Trichonida ( Modern Greek λίμνη Τριχωνίδα ; ancient Greek λίμην Τριχωνίς Limin Trichonis ) is the largest lake of natural origin in Greece . The lake is located in the east of the Aetolia-Acarnania Prefecture ( Greek Αιτωλοακαρνανία ) in the region of western Greece, south-southeast of the city of Agrinio , northwest of the city of Nafpaktos and north-northeast of the city of Messolongi .
The lake has a maximum extension of 18.2 km in length and is located at a height of 15 m above sea level. The neighboring Lysimachia Lake is one meter deeper (14 m). The maximum width is 7.5 km, the maximum depth of the lake 57 to 58 m (depending on the source), the mean depth is 29 or 30.45 m (depending on the source), with the water level fluctuating by around 1 m per year . This makes Lake Trichonida one of the three natural lakes in Greece that have a water depth of more than 50 m. The length of the coast of Lake Trichonida was calculated to be 52.1 km, the area occupied by the lake is 98.2 km² (according to other sources 98.6 km²). The calculated water volume of Lake Trichonida amounts to 2,868 to 2,990 cubic kilometers; Also in terms of water volume, the lake is the largest natural lake in Greece. The Trichonida lake drains an area of 215 or 250 km² (depending on the source).
The mean water temperature in Lake Trichonida is 15 ° C, the maximum 30 ° C. In summer, Lake Trichonida develops a so-called thermal stratification; layers of water with different water temperatures are formed, which is only reserved for the few deeper lakes in Greece. The lake never freezes over in winter. It belongs to the warm monomictic lakes.
Originally the lake covered large parts of what is now the Aetolia-Acarnania plain. It was thus also connected to a lake with Lysimachia Lake, which is neighboring today to the west . By siltation processes of Lake Trichonida shrank to its present size from 98.2 to 98.6 square kilometers.
The Panetoliko massif rises to the north and north-east of the lake . The shores of the lake are either forested or surrounded by agricultural land. 200 species of birds settle on Lake Trichonida, 50 of which are considered rare.
