Itaipu Lake (Portuguese: Lago de Itaipu, pronounced[ˈlaɡudʒiitajˈpu]) is a lake on the Brazil-Paraguay border, artificially formed in 1982 on the Paraná River with the closing of the gates of the Itaipu Hydroelectric Dam detour channel. It covers an area of 1,350 km2 (520 sq mi), 770 km2 (300 sq mi) on the Brazilian side and 580 km2 (220 sq mi) on the Paraguayan side. It also includes 66 small islands, 44 of which are on the Brazilian side and 22 on the Paraguayan side of the border.
Etymology
Itaipu is a word of Tupi origin meaning "noise of the river of stones" or "noisy river of stones", through the combination of itá (stone), y (water, river), and pu (noise).[1] Itaipu was the name of the small island that existed near the construction site of the dam.[2]
There is also one Brazilian town which belongs to the state of Mato Grosso do Sul: Mundo Novo.[5] These coastal towns receive 85% of the 65% of the resources allocated to the municipalities that are entitled to royalties. They benefit the most because they were directly affected by the formation of the power plant reservoir.[5]
The Itaipu Lake has become an important tourist attraction in the western region of Paraná.[6] To stimulate the development of sustainable tourism, sixteen municipalities bordering the lake were founded in 1990, in partnership with Itaipu Binacional, the Development Council for Cities Bordering the Itaipu Lake.[5] With representatives of the City Halls, City Councils and Commercial Associations of the riverside towns, the Council promotes the region's urban and rural socioeconomic development.[7][8]
Among the partnerships developed is the program "Integrated Tourism Paths to Lake Itaipu".[9] Resulting from the union of the Development Council for Cities Bordering the Itaipu Lake and Sebrae/PR, the program is managed by the Institute of Tourism and Events Caminhos ao Lago de Itaipu. It is responsible for marketing and assisting the Council and Sebrae in promoting regional tourism.
With the program, the cities allow visitors to Foz do Iguaçu to get to know natural areas, spaces and cultural manifestations, as well as rural, ecological, culinary and religious tourism options.
The itineraries include varied tourist attractions that allow the visitors to be in contact with the Italian, Germanic and indigenous cultures, musical performances, dance and handicrafts, as well as fish-based dishes such as pintado na telha, cucas, bolachas and homemade jellys. Visitors to Foz do Iguaçu can also take part in natural activities such as hiking and observing the fauna and flora, as well as water-related attractions such as boat trips and recreational fishing along Itaipu Lake.
Environment
Analyses carried out since 1986 have managed to identify the biodiversity of the region. According to the studies, in the area comprising the reservoir protection strip, reserves and shelters located on the Brazilian shore of Itaipu Lake, there are 305 species of birds, 44 species of mammals and 37 of reptiles. On the Paraguayan shore, where the native forest has not been heavily affected, 409 species of birds and 62 species of mammals have already been recorded.[10]
