The story of salmon is a quintessential Idaho story. Salmon are essential for the Nez Perce Tribe, as a source of food but also as a soul-deep connection to their life cycle.

Idaho Congressman Mike Simpson has made a bold proposal to save the species by getting rid of four dams on the Snake River that scientists say have severely cut their chances of survival. Idaho Matters talks with Idaho-based journalist Heath Druzin who partnered with the BBC on a new documentary about this extraordinary fish.
