his article addresses the struggle against the construction of the Middle Parana River Hydroelectric Project that took place during the 1990s in the provinces of Santa Fe and Entre Ríos, Argentina. The paper adopts the format of a photographic essay, but, given the fragmentary nature of the photo archive, the narrative of this historical event is developed by complementing the photographic record with other materials, including cultural productions of that period such as songs, poetry, panflets and banners used in the mobilizations against the megaproject, consultation with leading actors who participated in the struggle, and research results from previous academic work. The objective is providing a view of the struggle for a “dam-free Paraná river”, as the process is known, that incorporates additional information that makes it possible to revisit this historical process allowing space for alternative sensibilities in approaching it.
