The 15th round of negotiations to modernize the Columbia River Treaty was held in Vancouver on January 25 and 26. The Columbia River Treaty is a water management agreement that was implemented in 1964 between the United States and Canada. The U.S. prepaid Canada $64 million for a 60-year agreement to ensure flood control operations would be provided. The Columbia Treaty doesn’t have an end date but can be terminated by either country as of September 2024 or onward, if 10 years' notice is given.
