The Two Rivers policy led to the development of the WAC Bennett Dam on the Peace River and the Keenleyside Dam and Mica Dam on the Columbia River together with Duncan Dam at the top of Kootenay Lake. In 1964 the policy was formally realized with ratification of the Columbia River Treaty by the Government of Canada and the United States of America. Because of his Two Rivers policy, Bennett was successful in pressuring the federal government of Canada to allow British Columbia to 'sell electricity' to the Americans for a thirty-year period for the lump sum of US$275 million. The nationalization of BC Electric (1961), which was rolled over into the BC Power Commission to form BC Hydro, can also be seen as a part of this strategy.
