Following three women on a 78-day paddling expedition, “The Grand Salmon” explores the effects of four dams on the Lower Snake River and their impact throughout the watershed on rapidly dwindling wild salmon populations. For over 1,000 miles, these women navigate the same waterways wild salmon have for generations, connecting the source of the Salmon River to the Pacific Ocean. From high water to extreme temperatures, this team not only faces the same natural challenges the fish do each year, but brings viewers along to experience what the construction of these dams has done to our ecosystems and wildlife.
