Yusufeli Dam

From Wikipedia, the free encyclopedia

The proposed Yusufeli Dam and Hydro-Electric Power Project is to be located on the Çoruh River in the eastern Black Sea region of Turkey. The Yusufeli Dam will be the second largest dam within the larger Çoruh River Development Plan which plans to build 13 dams, of which 2 are operational and another 2 are under construction[1]. The Yusufeli Dam will have 33 km2 surface area, 60 km total length (including tributaries), and an average width of 550 m. Operating 8 hours per day over peak period it will produce 315-540 MW and is expected to cost 855 million USD. The proponents of this project are the Turkish Government and a consortium consisting of: Doğuş Inşaat ve Ticaret AS (Turkey) as leader; Alstom (Switzerland, France and Brazil); Coyne and Bellier (France); and Dolsar Mühendislik (Turkey).

[edit] Biological Impacts

When built, the Yusufeli Dam will have significant biological impacts including:

  • adversely affecting 21 nationally listed threatened plant species, of which all except one are endemic to Turkey[2]. 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[3].
  • 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.
