The mission of Rivers Without Borders is to safeguard the ecological integrity of the wild transboundary watersheds of Southeast Alaska and northwest British Columbia such as the Taku, Stikine, Alsek and Unuk, in a time of declining wild salmon populations and climate change.

Rivers Without Borders (then the Transboundary Watershed Alliance) formed in 1999 as an alliance of 22 groups to continue work begun in the Taku Watershed in 1995, and to extend that model of international collaboration to the Stikine and other transboundary watersheds. We now function as a distinct organization, while coordinating with a range of conservation groups, First Nations, and other allies.
