Environmental Effects of the Dam System on the Danube at Bos-Nagymaros

The building of dams and reservoirs on the Rhine, the Danube, the Rhone and other major rivers has led to grave and far-reaching damage and changed the natural conditions of these rivers. The natural water level drop of rivers is reduced and their natural drift is slowed down. The river bed and subsurface water levels rise, changing the natural flow of both surface and subsurface water. The conditions for flora and fauna are so dramatically affected that some species disappear. Forests are devastated and agriculture becomes impossible. In order to change this situation, countries concerned are making plans to improve these environmental effects.
