Sustainable Hydropower: Are Small Dams Really Better for the Environment? » Maine dam removal

Small hydropower dams (often defined as below 30 MW) are frequently presumed to be low impact.  However, this dam, Veazie, on the Penobscot River, had a capacity of 8.4 MW and was a major barrier to migration for the most important population of Atlantic salmon in the US. It was removed in 2013. Photo: ©Misty Edgecomb/TNC
