Northwest tribal and religious leaders have teamed up to call for updates to the Columbia River Treaty.  The treaty written in 1964 governs hydropower and flood control agreements between the U.S. and Canada, and key terms expire in ten years.  In the letter to President Barack Obama and Canadian Prime Minister Stephen Harper, the tribal and religious leaders say a modern treaty should include recognizing the rights of indigenous people and promoting environmental stewardship.  The leaders call for requiring fish passage at dams, protecting ecosystem health and cultural resources, adapting to climate change, and including tribal leaders and local communities in future decision making.  Federal agencies that manage the hydropower system have recommended updating the treaty, and Northwest lawmakers have asked the President to make negotiations a priority, but no talks have begun.
