Hydropower is generally considered as a “green” and clean energy. The reality is quite different and there are many aspects that are neglected when describing hydropower as a “green” energy, such as the negative impacts that dams and hydropower plants have on the environment and on the rivers’ ecosystem.
Indeed, the presence of dams affects the water quality and temperature, it changes the river flows and affects the water’s oxygen level with negative consequences on the whole river’s ecosystem. Moreover, dams create downstream and upstream barriers to fish, making migration almost impossible and thus affecting the fish capacity of completing their life cycle.
European anglers are very much concerned with the increasing development of hydropower in Europe. Hydropower is considered as a way to reach the EU climate and energy goals in an environmental-friendly way. On the contrary, besides the already mentioned negative effects on the environment, hydropower affects also recreational angling and tourism.
