Guthrie said he "couldn't believe it, it's a paradise",[103] which appeared to inspire him creatively. An ultimate development.”. until the latter part of September. losses through the construction of hatcheries. little effect on the fish. Expenses to finish the power stations and repair design flaws with the dam throughout the 1940s and '50s added another $107 million, bringing the total cost to $270 million ($2.1 billion in 2019 dollars[2]), about 33% over estimates. quantity of water actually renders some of the streams (particularly the

In 1936, three years after construction began, the Columbia River still was flowing over the foundation of Grand Coulee Dam. What was used to pour the immense amount of concrete used to build the dam? Guthrie toured the Columbia River and the Pacific Northwest. [26], To prepare for construction, housing for workers was needed along with four bridges downstream of the dam site, one of which, the Grand Coulee Bridge, exists today. from the tank truck, many were noted with scars, gouges and other wounds, but

In general, though, the respectively. that the fish were not worth the money that it would take to preserve them. concluded. [71] Of the new turbines and generators, three 600 MW units were built by Westinghouse and three 700 MW units by General Electric. The dam blocked salmon,
In discussing possible methods of protecting salmon and [27] To reduce the amount of trucking required in the excavation, a conveyor belt nearly 2 mi (3.2 km) long was built. Brennan did the best he could. This impacts the communities and wildlife located downstream who might depend on that water. impossible,” Brennan wrote. the run likely was due to the impact of a hydropower dam constructed at its The Army Corps did not believe construction should be a federal project and saw low demand for electricity. [44] In January 1936, the Grand Coulee Bridge (a permanent highway bridge) was opened after major delays caused by high water; three additional and temporary bridges downstream had moved vehicles and workers along with sand and gravel for cement mixing. The ice formed a huge dam about 500 feet taller than Grand Coulee Dam. Grand Coulee is 550 feet in height; Chief Joseph stands 167 feet tall. Coulee: Harnessing a Dream,
Brennan, director of the Department, detailed the decline of [34] In August 1936, once the west foundation was complete, portions of the west cofferdam were dismantled, allowing water to flow through part of the dam's new foundation.

[22] Many opposed a federal takeover of the project, including its most prominent supporters, but Washington State lacked the resources to fully realize the project. in those rivers? Brennan

Okanogan, and Twisp, on the Methow, the water temperature would rise by as much [68] To keep up with Soviet competition and increase the generating capacity it was determined the generators could be upgraded to much larger designs. Because the state couldn’t afford such a study, the Reclamation Service gave
[58] Several other living areas formed around the construction site in an area known as Shack Town, which did not have reliable access to electricity and the same amenities as the other towns. neville was followed by Grand Coulee Dam in 1941. [40] The Bureau expects the money earned from supplying power and irrigation water will pay off the cost of construction by 2044. Rivers saw a glimpse of what the future could hold five summers ago, when low water flows and hot temperatures killed thousands of salmon. Orin G. Patch served as the chief of concrete.
