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.

我们通过使用严格的科学标准和公众意见来定义和认证低影响水电；提供教育和推广；并构建我们的组织以融入和发展社区、保护和水电利益来实现这一目标。
