Yusufeli Dam

 ( Hydroelectric Power Stations In Turkey ) 

The dam's crest will sit at an altitude of above sea level while the normal operating level of its reservoir will be , maximum will be and the minimum . The reservoir surface area of will have a total storage capacity of and an active or "useful" storage of . The dam's spillway will be a service controlled chute type with a maximum discharge capacity of .

The dam will have an underground power station that is long, wide and high. Within the power station will be 3 x 180 MW vertical shaft .

Design activities will be carried out by Su-Yapi Engineering and Consulting Inc.

Construction is to be carried out by a Limak Holding-Cengiz Holding-Kolin consortium.

• Adversely affecting 21 nationally listed threatened plant species, (including Iris taochia) of which all except one are Endemism to Turkey. Of these threatened species 2 taxa are limited to Yusufeli and its surroundings, 8 are limited to the Çoruh Valley, and 6 to the Artvin-Erzurum area. Turkish Red Book for Plants shows that of these, 7 species are critically endangered, 5 are endangered and 9 are vulnerable.Ekim, T, Koyuncu, M, Vural, M, Duman, H, Aytac, Z & Adiguzel, N 2000, Türkiye Bitkileri Kırmızı Kitabi – Red Data Book of Turkish Plants, Türkiye Tabiatını Koruma Derneği – Turkish Association for the Conservation of Nature, Ankara, Turkey.
• Adversely affecting 12 nationally listed threatened mammal species including the; wild goat ( Capra aegagrus), chamois ( Rupicapra rupicapra), Persian squirrel ( Sciurus anomalus), forest dormouse ( Dryomys nitedula), brown bear ( Ursus arctos), Eurasian badger ( Meles meles), gray wolf ( Canis lupus), Mediterranean horseshoe bat ( Rhinolophus euryale), lesser horseshoe bat ( Rhinolophus hipposideros), greater mouse-eared bat ( Myotis myotis), Schreibers’ bat ( Miniopterus schreibersii) and pipistrelle bat ( Pipistrellus pipistrellus). Of these species the Mediterranean bat and wild goat are internationally listed on the IUCN Red List of Threatened Species. IUCN 2006, IUCN Red List of Threatened Species
• Adversely affecting 2 nationally threatened fish species, the Black Sea salmon ( Salmo trutta labrax) and brown trout ( Salmo trutta macrostigma). The Black Sea salmon's migration will be blocked because of this and the other planned and built dams. Existing populations of fish will be adversely affected by the construction of the dam and another 6 species populations may not recover due to the reduction of creek and river habitat needed for breeding.
• Potentially adversely affecting 5 butterfly and 1 dragonfly regionally rare species ( Polyommatus poseidon, Pseudophilotes vicrama, Pyrgus cirsii, Scolitantides orion, Thymelicus acteon, and Onychogomphus assimilis) of which 2 ( Pyrgus cirsii and Onychogomphus assimilis) are listed in the IUCN Red List.Eken G, Bozdogan M, I˙sfendiyaroglu S, Kılıç DT & Lise Y, (editor) 2006, Key biodiversity areas in Turkey, Doga Dernegi, Ankara, Turkey.
