With representatives from conservation and academic institutions from around the world, WWF and McGill University have led an effort to establish a common definition of a free-flowing river and develop a universal methodology for measuring river connectivity and identifying free-flowing rivers. This study is a global inventory that identifies rivers that remain free-flowing is in progress. The methodology for identifying free-flowing rivers globally can also be downscaled to support local needs.

Ultimately, this work is intended to inform further research and planning, and inspire the information, tools, and guidance needed to make more sustainable choices about infrastructure that impacts freshwater ecosystems.
