The artificial lake of Agia (Ayia) is located near the village of Agia, 9 km west of Chania. It is a small lake of 450 acres, which is close to the valley of Fasas. This valley is considered as the most humid of Crete. Agia lake receives water from underground springs and the river Xekolomenos.
The lake was a swamp before the Power Public Corp turned it to artificial, for producing hydroelectric power. Today, the power station is abandoned, but visitors still can see the old mechanisms.
