Photo of Tana Wilson’s maternal grandfather, Papa Whitmarsh with his daughter Rebel (Wilson’s mother, in shorts) and son (Wilson’s uncle), Shane, viewing Libby Dam and its surroundings, from the Treaty Tower. The photo was taken in 1975. As part of the Columbia River Treaty in 1964, Congress authorized Libby Dam’s construction and operations and the dam is the only U.S. dam among the four storage dams built in the headwaters of the Columbia River system under the Treaty, making it the only Corps-operated facility in the nation to have both upstream and downstream international impacts.
