Low Impact Hydropower Institute

Our Vision: We envision a world where hydropower puts people and the environment first.

Our Mission: We recognize and support hydropower that prioritizes environmental, recreational, historical, and cultural resource protection.

We do this by defining and certifying Low Impact Hydropower using rigorous science-based criteria and public input; providing education and outreach; and structuring our organization to integrate and evolve with community, conservation, and hydropower interests.
