Abstract: The new Osoyoos Lake Control Structure has been built on the Okanogan River at Oroville, Wa. The site is about 2 miles downstream from the outlet of Osoyoos Lake, and about 9 miles south of the United States-Canada border. This structure replaces the wood and concrete Zosel Dam which had been built in 1927 to form a log storage pond for the adjacent Zosel Lumber Company mill. The original dam had deteriorated, causing concerns for its safety, despite recent repairs. Originating in Canada, the Okanogan River is a tributary of the Columbia River, and is a source of water for a major portion of the Okanagan fruit-growing area in British Columbia and the Okanogan Valley in Washington State.
