The Columbia River Treaty (CRT) is a nearly 60-year-old agreement between the U.S and Canada that has been recognized globally as a model for international cooperation on hydropower and flood control objectives. However, the treaty has also had detrimental social and environmental implications. Now the Treaty is being renegotiated and adaptive management may help optimize multiple objectives in the face of an uncertain climate future. This talk will cover a brief history of the Columbia basin, benefits and impacts of the original CRT agreement, and possible future directions of the Treaty. Tyler will also share insights from a workshop on adaptive management hosted by the Canadian Studies Program in spring 2019 and introduce his current research focused on managing CRT reservoirs for ecosystem function.
