Site description The Battures de Beauport and Chenal de L’île d’Orléans are on the St. Lawrence River just east of Quebec City. The site includes the L’île d’Orléans channel westward from L’Ange Gardien, and continues westward to include the Beauport tidal mudflats on the north side. In places, tidal flats can be as wide as 800 metres, with extensive Scirpus marshes. Immediately adjacent to the shorelines are highways, a railway and heavily urbanized areas. The waters are turbulent with strong currents and tides. Four species of fish that are in need of protection, such as American Eel and American Shad use the channel.
