Coruh river starts from Mescit Mountains of Bayburt, Turkey and reaches Black Sea in Batum, Georgia. The total length of the river is around 431 km. and 410 km of it in the boundries of Turkey and the remaining 21 km in the Georgia. The annual discharge of the river is 6.3 billion cubic meter. Coruh is the fastest running river of the Turkey with an elevational difference of 1420 m. It carries 5.8 million cubic meter of sediment each year. Ten dams are planned to construct on the main river while 21 planned to construct on the branches of the river. They will generate 10.6 billions kWh energy per year. Seven of these dams are located in the vicinity of Artvin. Construction of new roads have also started to solve the transportation problem of the area because some part of the roads are going to be covered by the water. Road construction will damage the forests of the valley due to high slope in the area. Fish species living in the river such as Salmo trutta labrax, Salmo trutta lcapius, Cypirinus carpio, Barbus cycloepsis and Silurus glanis are going to lose their habitat. The region is rich in endemism. The number of endemic species is 119 for Artvin and some of them grows in the main valley of Coruh river. They will lose their habitat after the construction of the dams
