It recommended the Grand Coulee Dam and nine others on the river, including some in Canada. The report stated electricity sales from the Grand Coulee Dam could pay for construction costs. Reclamation—whose interest in the dam was revitalized by the report—endorsed it. Although there was support for the Grand Coulee Dam, others argued there was little need for more electricity in the Northwest and crops were in surplus. The Army Corps did not believe construction should be a federal project and saw
Grand Coulee Dam the year. For example, while the dam may generate at nameplate-capacity in the spring, decreased river flow in the fall means less power can be generated the rest of the year, resulting in a lower capacity factor. The proposal to build the dam was the focus of a bitter debate during the 1920s between two groups. One group wanted to irrigate the ancient Grand Coulee with a gravity canal while the other pursued a high dam and pumping scheme. The dam supporters won in 1933, but for fiscal reasons the initial design was for a "low dam" tall which would
