Variations des proportions des principaux taxons entre 2009 (avant travaux) et 2012 (après travaux) pour les stations sur le Bocq en amont (jaune) et en aval (rouge) du déversoir de Spontin, ainsi que sur la station contrôle de Senenne (bleu). * Simuliidae non prises en compte pour la station de Senenne en 2012 en raison d'une surabondance non pertinente sur le plan écologique (Ladle et al., 1977).
