largely due to British Columbia needing to negotiate with the Canadian federal government to clarify issues of authority and responsibility. So that was sort of the original round of negotiation processes. And the treaty as it emerged has two primary focuses, hydroelectric power and flood control. The terms of the tree specified that Canada would provide about 15 million acre feet of storage usable for improving the flow of the Columbia River. This is really for flood control purposes to minimize downstream flood damages in both the US and Canada. And as compensation, the US made three lump sum payments totaling $64.4 million to Canada when the dams were completed. And that amount was based on an estimate of half of the present value of future US flood damages prevented. So the operation of the Columbia Retreaty storage creates hydropower benefits in both countries. And the CRT requires that the downstream power benefits in the US due to the operation of the Canadian storage be shared equally between the two countries. This is known as the Canadian entitlement and under the terms of the treaty, Canada can opt to sell the entitlement back to buyers in the US. And actually to pay for construction of the dams. British Columbia sold the Canadian entitlement to a consortium of utilities in the US for 30 years beginning in 1964. So the treaty really is sort of premised on this idea of mutual gains to both countries both in terms of flood control and hydroelectricity. However, there were also sort of losses created.
