well as having plundered the locals and reduced them to poverty. Lieutenant Alexander Bulatovich led a second Ethiopian expedition which reached the lake August 21, 1899, and was equally destructive. Despite this, the Frenchmen in the party accurately mapped for the first time many of the meanders of the Omo River delta. This rendition of the Omo River remained in use until the 1930s when Italian colonial cartographers made a new and more accurate rendition of the river and its delta. Hydroelectric power stations There are several power stations and dams in the Omo River basin which are named after the Gilgel Gibe River and Gibe River, which are tributaries of the Omo River. Despite the somewhat confusing naming they are native power stations and dams located on the Omo River. Gilgel Gibe II Power Station The Gilgel Gibe II Power Station is a hydroelectric power station on the Omo River with a power output of 420 Megawatt (MW). The power station receives water from a tunnel entrance on the Gilgel Gibe River in a run-of-river scheme. The tunnel entrance is sitting downstream of the Gilgel Gibe I Dam also on the Gilgel Gibe River with which it forms a hydroelectric cascade. Gibe III dam The Gibe III Hydroelectric dam is a 243 m high roller-compacted concrete dam with an associated hydropower plant on the Omo River in Ethiopia. It is the largest hydropower plant in Ethiopia with a power output of about 1870 Megawatt (MW), thus more than doubling total installed capacity in Ethiopia from its 2007 level of 814 MW. A controversy has ensued over its construction, with several NGOs forming a campaign to oppose it. According to Terri Hathaway, director of International Rivers' Africa programme, Gibe III is "the most destructive dam under construction in Africa." The project would condemn "half a million of the region's most vulnerable people to hunger and conflict." A group of international campaigners launched an online petition against Ethiopia's dam project over human rights concerns. However, Azeb Asnake, project manager of Gibe III for the government power provider, said that a mitigation measure has been prepared in case something happens. Apart from this, Asnake predicted no adverse consequence from the project, adding that more than half of the people that live in the area are dependent on food aid and that the new station is necessary as currently the corporation is only
