Boats on Kerkini Lake, Greece.
I do not know why they call it a lake, not a dam!
The lake is the marsh of the Struma River.
In 1932 the artificial lake was created by blocking in the east and the south with a dam wall.
At the moment it is a reserve and there are many protected bird species.
It is also rich in freshwater fish whose catches are the livelihood of local fishermen.
Usually, when I visit it, I pay more attention to the birds.
But I think it is worthy to take at least one photo of their livelihood!
