Episode description
A bitter fight over fish is playing out in the American West. Sockeye salmon make one of the great migrations in the world, swimming 900 miles from the Pacific Ocean to 6,500 feet up in Idaho’s Sawtooth Mountains, where they spawn and die - but that journey may not happen much longer.
In addition to the gauntlet of predators the fish face, from orcas on the west coast to eagles in the mountains, they are running into a man-made obstacle: dams.
Most scientists agree the dams need to go for the fish to live, but the dams provide clean energy and an inexpensive way for farmers to get their crops to international markets.
Heath Druzin investigates how a bitter fight is underway in the American West pitting Native American tribes, fisherman and conservationists against grain growers and power producers.
Meanwhile, time is running out for the iconic species.
