Kettle River (Columbia River tributary) loops south, crossing the Canada–US border into the United States, through Ferry County, Washington, before flowing north back into Canada, passing by Grand Forks, British Columbia, where the Granby River joins. After flowing east for about , the river turns south again, just south of Christina Lake, entering the United States again. It then flows south, forming part of the Ferry-Stevens County line, before joining the Columbia River near Kettle Falls, Washington. The Columbia River at this point is a large reservoir impounded behind Grand Coulee Dam, called Lake Roosevelt. The Kettle enters the lake at the Columbia's river mile
Grand Coulee Dam Frank A. Banks served as the chief construction engineer. Bert A. Hall was the chief inspector who would accept the dam from the contractors. Orin G. Patch served as the chief of concrete. Construction conditions were dangerous and 77 workers died. 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. The Bureau of Reclamation provided housing and located their administrative building at Engineer's Town, which was directly downstream of the construction site on the west side of the river. Opposite Engineer's Town,
