The writer of this paper shows how, according to most scientists, dam removal would be the best option for recovery of native salmon and steal head in the Snake River system. The paper examines the human costs and shows how many people rely on the river in its current state for their livelihood. The paper discusses the issues of the cost and benefits of dam removal that lawmakers must weigh before deciding this complicated issue.
From the Paper:"As it is with any issue of importance all sides and perspectives must be explored before any kind of decision can be made. So, the question at hand is should the four dams (Ice Harbor, Lower Monumental, Little Goose and Lower Granite) on the lower Snake River be removed, to aid in the recovery of endangered Idaho salmon and steelhead stocks. At the beginning of this century salmon and steelhead runs in the Columbia and Snake River basins were unequaled. I read accounts, from the 1920's and 30's, of fishermen hauling in half mile long seine nets with draft horses, containing 30,000 tons of salmon at a time, and catching up 94,000 tons of fish a day in the mouth of the Columbia River. Not only where the fish more plenty full they where larger. I saw a picture of an 82-pound Chinook caught in 1921 in Astoria. These massive salmon where known as June hogs and their spawning grounds where found all the way up in British Columbia. These massive specimens ceased to exist after the construction of the Grand Coulee dam in 1941, which closed off over a thousand miles of prime spawning grounds to the north. The loss of these mighty specimens signaled the fate of the rest of the species in the coming decades. The Grand Coulee was just the first in a series of dams, which have destroyed critical habitat and impeded the upward and downstream migration of the once plentiful fish. When Lewis and Clark visited this region in 1802 approximately 16 million salmon and steelhead returned each year to complete their life cycle; today approximately 300,000 fish will return, a small fraction of the once mighty run. Dams are not the only factor leading to the extinction of salmon and steelhead, there are other important factors such as: pollution, stream bank deprivation caused by logging and grazing, non-favorable oceanic conditions, over fishing, and predation. But, for the purpose of this paper I will be discussing the environmental as well as the social effects of removing the dams on the lower Snake. "
