Dam breaching gets a surprise endorsement

This article focuses on Don Chapman, the guru of fisheries biologists, who had staunchly defended technological fixes for the imperiled fish, recommending hauling salmon past the dams from their spawning grounds to the Pacific Ocean. However, Chapman changed his mind about breaching the four lower Snake River dams. He cited new scientific evidence showing that the Columbia River is warming. He said, warmer water will reduce the habitat available for spawning and even cause the North Pacific, where the fish mature, to lose much of its productivity. Some of his former students, now fisheries managers in Oregon and Idaho, were pushing hydroelectric dam operators to make eight dams between the Pacific and Idaho less deadly for imperiled salmon.
