<br /> <br />S na/(? 2?Jver <br /> <br />Hells Canyon. This alternative may seem attractive, but retrofitting this <br />kind of technology would carry a frighteningly large price tag, And even if <br />sediment could somehow be introduced to the river channel. that alone <br />might not be enough to rescue the beaches or help the salmon. Once <br />scrutinized. none of these alternatives offer a balanced solution to the <br />issue of downstream effects at Hells Canyon. As much as we might wish <br />to work miracles. sometimes the only fruit born of the study of the <br />downstream effects of dams is a realistic assessment of relative values <br />and environmental costs. <br /> <br />~ <br /> <br /> <br />27 <br />
