Matka (lake)

Matka is the oldest artificial lake in Macedonia, with its reservoir being built in 1938. It was created by damming the Treska River with the dam of St. Andrew and forming an artificial reservoir in the Matka Canyon.

The water from the lake is used for hydroelectric power generation as well as irrigation of the surrounding villages. The lake is also stocked with fish and is frequently used for recreational fishing. Within the lake, there is the underwater cave called Vrelo, one of the deepest underwater caves in Europe, with a depth of over 203 m.
