Hydropower generation induces artificial fluctuations of flow and thus of hydrodynamic parameters in rivers, downstream of hydroelectric impoundments. On the Fontaulière river (Ardèche basin, France), the ecological effects of two different hydropeaking regimes were tested and compared to a reference upstream reach. Fish, invertebrate and epilithon communities were surveyed in these different reaches. The results enabled to classify the factors responsible for the observed effects. The base flow between peaks was the most important for the studied site. When it was too low, aquatic communities were destructured in comparison with the natural reach. These results enabled to suggest a current velocity threshold to respect in order to determin...
