This is a solid piece of research and reminiscence, telling the story of the colonization of the Columbia River system, first by white settlers who converted lands into farms, then by politicians and engineers who converted wild rivers into reservoirs. The ecological damage of the latter is given pride of place in this account, but the indigenous inhabitants of these lands and watersheds and their experience is more or less lumped together with that of ranchers, farmers, and orchardists, all of whom suffered alike from the mega-dam projects that began with Grand Coulee in the United States in the 1930s but continued in Canada in the 1950s and 1960s. A more systematic approach might have compared the ways in which indigenous inhabitants dwelled in the land compared to that of the later white settlers and then compared again lastly to the current mode of being in the land of the Kootenays, as that region is the main focus of the book. The author reminds us of the need, to alter one of Aldo Leopold's phrases, to "think like a river", and I think the book would have benefitted from more explicit examples of how that has been done successfully in the past. That said, it is a good introduction to the intricacies of the Columbia River Treaty, and it forms a good companion piece to other books like Jim Lichatowich's remarkable 1999 book Salmon Without Rivers and Robin Wall Kimmerer's Braiding Sweetgrass, books that remind and show us how unquestioned assumptions and hubris can lead to catastrophic consequences, but also how humility, attentiveness, and gratitude can start to lead us back.
