The Low Impact Hydropower Institute (LIHI) is a non-profit 501(c)(3) organization dedicated to reducing the impacts of hydropower generation through the certification of hydropower projects that have avoided or reduced their environmental impacts pursuant to the Low Impact Hydropower Institute’s criteria.

There are thousands of hydropower dams in the United States located on many of our most important rivers and streams. These dams can create pollution-free energy, but they can also produce significant adverse impacts on fish and wildlife and other resources.

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.

為此，我們使用嚴格的科學標準和公眾意見來定義和認證低影響水力發電；提供教育和外展活動；建構我們的組織，使其與社區、保護和水力發電利益相融合和發展。
