Dams were once a symbol of progress and control over nature, whereas today they are instead at the centre of lively debate by those who evaluate their impact on the ecosystem negatively. In the USA there is a growing movement asking for the dams constructed in the 19th and 20th century to be removed, so that rivers can return to their original courses. The fruit of three and a half years of work, for the first time DamNation documents the spectacular removal of a number of dams and the subsequent consequences on the environment. A journey through the history and landscape of the United States, where nature and freedom are inseparable.
