Hydropower Dams Hamper Migrating Fish Despite Passage Features, Study Finds
State-of-the-art fish passage facilities built into river dams have failed to help fish migrate upstream from the sea to reach their spawning grounds, a study has revealed. The research, led by a UA graduate, concludes that only dam removal would enable up-river migration in the three large and historically important river systems studied – the Merrimack, Connecticut and Susquehanna.
