The salmon were cut off from reaching their spawning grounds by a massive landslide into the river near Big Bar, B.C. But those aerial migrations — a last-ditch effort to save the stocks — will soon be over. On Wednesday, the Department of Fisheries and Oceans (DFO) announced plans to build a $176.3-million fish ladder, or fishway, to help the salmon move up and down the river at the site in the traditional territory of the High Bar and Stswecem'c Xgat'tem First Nations.
