Young people from Lewiston and throughout the Pacific Northwest will gather at Hells Gate State Park on Saturday to advocate for salmon and the removal of the four dams that made the community a seaport.

The debate over the best way to save wild salmon and steelhead that spawn in the Snake River and its high-elevation tributaries, and whether the lower Snake River should be restored to its free-flowing state for their benefit, is more than three decades old now. It was raging before many of the participants in Saturday’s event were born.
