Canadian aspects of the Columbia treaty

On January 17, 1961, the United States and Canada signed the Columbia River Treaty. This comprised an agreement between the two governments for the cooperative development of power, and the mutual provision of flood control benefits, in the basin of the magnificent river whose name has been in our headlines for so many years. The treaty was supplemented by a codicil signed three years later on January 22, 1964, which spelled out and clarified certain of its terms. At the same time agreement was reached on the terms of sale under which the United States would be entitled to use the Canadian share of the downstream benefits resulting from dam construction in British Columbia for a period of 30 years.
