Hydro dams are often blamed for the demise of eels in the Ottawa River, but a group of researchers has been trying to figure out a way to provide them a safe passage upstream.
About 98 per cent of the eel population has vanished from the Ottawa waterway over the years, making the slimy, slithering fish an endangered species. Turbines within the dams created a major barrier for eels as they travel upstream — they would either trapped or chopped up along their journey. The Canadian Wildlife Federation and the Ottawa Riverkeeper worked with Energy Ottawa to install new sets of turbines that create safe passage channels through dams on the Ottawa River, including the one at Chaudière Falls.http://www.cbc.ca/news/canada/ottawa/researchers-tag-release-eels-ottawa-river-1.4202694
