Zosel Dam

Zosel Dam is a dam in the U.S. state of Washington that blocks the Okanogan River just south of Osoyoos Lake to control upstream water levels. The dam was built as part of the larger Osoyoos Lake International Water Control Structure, a joint venture of the Washington State Department of Ecology and the British Columbia Ministry of the Environment. The dam was designed by the Canadian firm Acres International Limited and built by the American firm Rognlins Inc.
