Why we should be destroying more dams

What happens when an old dam stops serving its purpose—but continues blocking an entire river ecosystem? In this documentary-style video, we explore the growing movement to remove obsolete dams and restore free-flowing rivers. From the dramatic recovery of the Enobieta Dam in northern Spain to salmon returning to previously blocked waters in Finland, this story examines how rivers, forests, fish, sediment, and entire ecosystems can respond when barriers are removed. We’ll explore: Why obsolete dams can damage river ecosystems How dams affect fish migration and sediment flow The remarkable recovery of the Enobieta river system Why salmon returned after dam removal The difference between useful and obsolete dams The economic and environmental challenges of dam removal Why Europe is restoring thousands of kilometers of free-flowing rivers Why some countries are still building new hydropower dams The future of dams, hydropower, water security, and river restoration This is not a story about destroying every dam. It is about asking a more important question: Does every dam still have a purpose?

It discusses scientific research, environmental restoration, infrastructure, hydropower, and publicly reported projects. Individual dam-removal outcomes can vary depending on local geography, ecology, engineering conditions, costs, regulations, and community needs. The video does not suggest that every dam should be removed or that hydropower is inherently harmful. Always consult official government agencies, scientific publications, engineers, and environmental authorities for site-specific information.
