From page 199...
... This situation is es pecially troubling because of prospective future climate warming (which could entail not only higher water temperatures but also further decreases in low flows) and demands for additional di versions of Columbia River water during low-flow periods.

From page 200...
... The seasonality of Columbia River flows and changing de mand patterns for additional water from various users in differ ent parts of the river basin suggest that sound water management decisions require a comprehensive basinwide water management scheme. Ideally, the management framework would have the flexibility to respond to the seasonality of Columbia River flows and have the flexibility to responsibly transfer water from lower value to higher-value uses.

... To reiterate and reinforce this report's six key findings and recommendations, they are repeated here: · Within the body of scientific literature reviewed as part of this study, the relative importance of various envi ronmental variables on smolt survival is not clearly estab lished. When river flows become critically low or water temperatures excessively high, however, pronounced changes in salmon migratory behavior and lower survival rates are expected.

... Allowing for additional withdrawals during the critical periods of high demand, low flows, and compara tively high water temperatures identified in this report would increase the risks of survivability to listed salmon stocks and would reduce management flexibility during these periods (Chapter 7)
