The Gallikos ( Greek Γαλλικός , ancient Greek Ἐχείδωρος Echeidōros or Ἐχέδωρος Echedōros ) is an approx. 60 km long river in the Greek region of Central Macedonia . It rises northeast of the city of Kilkis on Mount Dysoros and flows from north to south to its confluence with the Thermaic Gulf .
A value between 930 and 1022 km² is given for the catchment area of the Gallikos River. The upper (northern) catchment area close to the source is given with an area of 750 km² and belongs to the regional district Kilkis; the river in this area has a length of 43 km. The mean height of this area is 337.5 m, the maximum 1,180 m.
The mean annual rainfall in the upper catchment area is 480 mm; 70% of this precipitation falls between October and May. The maximum amount of precipitation reaches 1,180 mm per year. The mean annual water flow at the Nea Filadelfia measuring station northeast of Thessaloniki is 0.7 m³ (700 liters) per second. In summer the Gallikos almost dried up.
The river carries or carried dissolved gold ( soap gold ) with it. Between 1953 and 1960, the Greek Goldfields company extracted 1,355 kg of gold with a fineness of more than 960 from the Gallikos. The gold comes from the Kroussia and Vertsikos Mountains and enters the Gallikos through the Megalo Potami tributary. This tributary flows into the Gallikos about 10 km southeast of the city of Kilkis.
