Located in the regional unit of Drama, very close to the settlement of Paranesti, Thesavros Reservoir Lake is an artificial lake constructed across the bed of the river Nestos. The lake was formed following the construction and operation of the hydroelectric dam of Thesavros; it stretches along the old riverbed, making the Nestos look from above like a sea. Along with the neighboring dam and Reservoir lake of Platanovrisi, this is a fascinating project which ultimately intervenes in the natural landscape in a dramatic way, causing feelings of awe and admiration to the visitor.
