KETTLE FALLS, Washington – Richard Armstrong knelt on the Columbia River’s rocky shoreline, a feather in his hand, a prayer for salmon in his heart. For thousands of years, his ancestors fished at this site. Perched on platforms above the thundering cascades at Kettle Falls, they took hundreds – sometimes thousands – of fish daily from the river: blueback sockeye salmon, silvery steelhead, 40- to 60-pound spring chinooks called “June hogs” and eel-like lampreys.
