The Thissavros Dam (Nestos Reservoir; Greek: Φράγμα Θησαυρού, Techniti Limni Nestou / Thissavrou) is one of several dams on Nestos (Mesta) in northeast Greece near the Bulgarian border. Nestos, who comes from Bulgaria, will be dammed four times on the Greek side at the Thissavros, Platanovryssi, in future Temenos and Toxotes to use the hydropower potential and for irrigation purposes. The storage heights are 172 m, 95 m, 45 m and 4 m.

The Thissavros dam is the first in the cascade. It is about 12 km above the Platanovryssi dam and 18 km above the future Temenos dam. It also functions as a pumped storage plant , the lower basin of which is the Platanovryssi reservoir (storage space: 63 million m³).

The dam consists of loose rock material with a central sealing core made of clay.

The hydropower plant has three turbines in a cavern . Each has a capacity of 128 MW, a total of 384 MW. This generates 440 million kWh of electricity per year. The hydraulic head is 141 m.
