Rampart Dam - Planning

Planning

The first serious consideration of a dam project was made in a 1954 U.S. Army Corps of Engineers assessment of the resources of the Yukon and Kuskokwim River basin. Engineers considered Rampart Canyon to be a prime site for a hydroelectric dam. In April 1959, four months after President Dwight D. Eisenhower signed Alaska's declaration of statehood, junior U.S. Senator from Alaska Ernest Gruening passed a resolution calling for the Corps of Engineers to begin an official study of the project, and $49,000 was allocated by the federal government for that purpose. Preliminary estimates said the project would cost $900 million (1959 dollars) and generate 4.7 million kilowatts of electricity. At the time, the largest hydroelectric project in Alaska was the Eklutna Dam, which produced just 32,000 kilowatts.

The project competed with the smaller-scale Susitna Hydroelectric Project proposed by the Federal Bureau of Reclamation for south-central Alaska, but thanks to Gruening's support and that of other backers, the Rampart project took precedence. The Rivers and Harbors Act of 1960 passed by the U.S. Congress in that year included a $2 million appropriation to conduct a full four-year feasibility study of the project, including its economic feasibility and the impact it would have on fish and wildlife. In March 1961, a team of engineers from the Corps' Alaska district began drilling operations at the site to determine bedrock depth and gather other data. In order to examine the economic feasibility of the dam, the Corps of Engineers created the Rampart Economic Advisory Board (REAB) in February 1961. The REAB hired David E. Lilienthal's Development and Resources Corporation in April to complete the study, and a team of Corps engineers and REAB members arrived in the state in June to study the Rampart project first-hand. At that time, Sen. Gruening estimated that the project would cost roughly $1.2 billion to complete, $8.2 billion in 2007 dollars.

As investigation and planning work continued, the Corps of Engineers reached an agreement with the Department of the Interior, the parent agency of the Bureau of Reclamation, in March 1962. The agreement stated the Corps would have responsibility for design and construction of the project, while the Interior Department would be responsible for running and maintaining the dam after completion. In the planning stages, the Interior Department also would be responsible for examining the economic feasibility of the project and its effect upon natural resources. This agreement negated much of the work of the REAB to that point, as the Interior Department promptly began its own three-year study of the dam's economic feasibility and environmental impact. The DRC report, though trumped by the Interior Department's new precedence in such matters, nevertheless released a report in April 1962, stating that the project was economically feasible and would attract new industries to Alaska. Meanwhile, the Corps of Engineers continued engineering studies.

The interim Corps of Engineers report was released in December 1963, and reported that building the dam was feasible from an engineering standpoint. President John F. Kennedy supported the project, and lobbied for an appropriation of $197,000 (1963 dollars) to continue study of the project. The needed money was included in a House appropriations bill, and studies continued. The initial report included some figures about the size of the project. The dam would be a concrete structure 530 feet (162 m) high and about 4,700 feet (1,430 m) long. It would raise the height of the Yukon River from 215 feet (66 m) above sea level to approximately 445 feet (136 m). The resulting reservoir would be 400 miles (640 km) long, 80 miles (130 km) wide, and have a surface area greater than that of Lake Erie. The power facilities for the project would produce a maximum of 5 gigawatts of electricity. In total, the proposed reservoir was anticipated to cover an area of 10,700 square miles (27,700 km2) and have a capacity of 1,300,000,000 acre feet (1,600 km3).

In April 1964, the U.S. Fish and Wildlife Service (FWS) released its report on the project. Though only a part of the larger Department of the Interior study, the FWS report came down strongly opposed to the dam on the grounds that it would irrevocably destroy the Yukon Flats, a critical waterfowl breeding ground. In January 1965, the Bureau of Land Management set aside almost 9,000,000 acres (3,600,000 ha) of land for construction of the dam and reservoir. It was a typical process that had been done for other dam projects several times before, but the amount of land to be set aside generated several months of hearings before the decision. In June 1964 the Natural Resources Council asked Stephen H. Spurr, Dean of the Graduate School of the University of Michigan and an authority on forestry and forest ecology, to form a group to evaluate the proposed Rampart Dam. The Spurr report determined that the scenarios offered as justification for the project were overly optimistic with respect to Alaska’s projected long-term population growth, its per capita use of electricity, and the predicted rate of entry of electroprocess industries like the aluminum industry (which had substantial power requirements) into Alaska. Moreover, the proposed dam would have greatly reduced the catch of five species of Pacific salmon, especially the chinook (king), chum (dog) and coho (silver) salmon. It would also eliminate vast numbers of migratory waterfowl, including an estimated 1.5 million ducks and 12,500 geese that migrated annually from the Yukon flats. There would also have been a sharp decline in both large mammals - the moose, black and grizzly bear, and caribou - and smaller mammals: muskrats, mink, beavers, and river otters in aquatic habitats, and marten, wolverines, weasels, lynx, snowshoe hares, red fox and red squirrels in terrestrial or upland habitats. Spurr’s report noted that "is a truism of wildlife ecology that displacement of a population from the area where it normally lives is tantamount to eliminating it completely. Adjoining habitats ordinarily are carrying all the wildlife that the local resources will support. In short, loss of habitat is synonymous with loss of the animal population supported by the inundated habitat." In March 1966 Spurr’s team issued its final report, finding that the dam was not a cost-effective investment.

Also in January 1965, the Department of the Interior completed its three-volume, 1,000-page study of the Rampart project's feasibility and impact. The Fish and Wildlife study released in 1964 was included, as were studies of the impact on the region's Alaska Native population. United States Secretary of the Interior Stewart Udall then created a task force to review the findings before he made a final decision. Throughout 1965 and 1966, opponents and proponents of the project funded studies of their own, aimed either at supporting or rejecting the arguments for the dam.

In June 1967, the Department of the Interior made its final recommendation and suggested that the dam not be built. Secretary Udall cited the fish and wildlife losses that would result, the availability of less-costly alternatives, and the fact that no recreational benefits would accrue.
