A instalação da UHE de Belo Monte alterou a dinâmica regional e desencadeou transformações territoriais expressivas no campo e na cidade. O artigo trata das consequências dos deslocamentos compulsórios. Elegeu-se como objetivo analisar as implicações no espaço intraurbano em Altamira, para os moradores que residiam na área diretamente afetada. Utilizou-se, como percurso metodológico a revisão bibliográfica, o estudo de caso, o trabalho de campo e a aplicação de formulários. Concluiu-se que a instalação de hidrelétrica foi responsável pela alteração da segregação, para a sociedade local, através de novas relações sociais engendradas, materializadas no espaço intraurbano da cidade. Infere-se que os remanejados para novos bairros sofrem uma nova forma de segregação, planejada e ordenada corporativamente.

The trauma that resulted from the construction of large hydroelectric dams in the Amazon is marked by major social and environmental restructuring, plunder, and impacts, on Indigenous Lands, Conservation Units, and residents on the outskirts of cities or through the country roads. In general, the effects caused by the Belo Monte HPP gain prominence and production, in which one of them composes the objective of this article: to analyze the impacts on the fishing territory. Having as methodological path the bibliographic review, field, and relative work with the fishermen of the Fishing Colony Z-57. It appears that the installation of the plant ended up deleteriously altering the systemic and cultural relations, under which the fishing territory is expressed. Compromising it, translating into low fishing stocks in the communities; a decrease of up to 70% in fisheries production and, consequently, an increase in pain and economic costs for carrying out the activity. It was evident that the legal frameworks and the licensing instruments, all the judicialization resulting from these infrastructure projects, and the struggle imposed on their installation, were not capable of safeguarding the interests of society - fishermen, specifically - in the face of the despoliation effect of the construction of the hydroelectric dam on the fishing territory.
