Lake Pampulha (Portuguese: Lagoa da Pampulha, ) is an artificial lake located in Pampulha, Belo Horizonte, Brazil. It is also the name of an administrative region ("região administrativa") of Belo Horizante, and the name of one of 29 neighborhoods ("bairros") within the administrative region of the same name. The lake was built in the early 1940s during the mayoralty of Juscelino Kubitschek, later president of Brazil from 1956 to 1961. Pampulha was created as a source of water for the city of Belo Horizonte, but quickly became polluted.
