Fishwheels of the Columbia examines the intensive industrial salmon harvest and specialized riparian engineering situated along the powerful, constricted channels of the Columbia River Gorge. Donaldson and Cramer detail how the region's formidable hydro-topography—specifically the narrow, bedrock-lined chokepoints of the Cascades and Celilo, the immense hydraulic force of the river's turbulent currents, and the steep, rugged banks of the gorge—strictly dictated the margins of early commercial fishery placement, riparian land monopolization, and the highly specialized mechanics of the river-driven harvest. By mapping the construction of massive, current-powered fishwheels securely anchored in strategic river narrows to intercept immense, upriver-migrating salmon runs, functioning entirely as mechanical extensions of the river's own kinetic energy, the narrative highlights how this specific riparian geography anchored a highly efficient, hyper-localized monopoly on marine resource extraction. Ultimately, this industrial and environmental record serves as a localized spatial history, demonstrating how the immense hydrological forces, severe topographical constrictions, and rich anadromous ecology of this Pacific Northwest waterway fundamentally shaped the highly engineered, extraction-driven character of the early Columbia River fisheries.
