Report to the Western Water Policy Review Advisory Commission.
Using the Columbian River Basin as an example, explores the ecosystems of rivers of all sizes in mountains and valleys, and discusses the impact of human interaction.
Flows of the Columbia River, although modified substantially during the twentieth century, still vary considerably between seasons and between years. Lowest flows tend to occur during summer months when demand for irrigation water is at its highest and when water temperatures are greatest. These periods of low flows, high demand, and high temperature are critical periods for juvenile salmon migrating downstream through the Columbia River hydropower system. Although impacts on salmon of any individual water withdrawal may be small, the cumulative effects of numerous withdrawals will affect Columbia River flows and would pose increased risks to salmon survival. The body of scientific knowledge...
Discover the diversity of the Columbia River watershed and the importance of the river's treaty renegotiation--a once-in-a-lifetime chance to reshape our region's future
Considers (81) H.R. 5472.
A River Captured explores the controversial history of the Columbia River Treaty and its impact on the ecosystems, Indigenous peoples, contemporary culture, cross-border politics and recent history of the Pacific Northwest. Long lauded as a model of international co-operation, the Columbia River Treaty governs the storage and management of the waters of the upper Columbia River basin, a region rich in water resources and with a natural geography well suited to hydroelectric megaprojects. The Treaty also displaced more than 2,000 residents of over a dozen communities, flooded and destroyed archaeological sites, and upended once-healthy fisheries. Paying special attention to First Nations hist...
