Libby Dam

Libby Dam Project is a multi-purpose water resource development.  Its purposes are flood reduction, hydropower, recreation, and environmental stewardship. We recognize that our day to day activities in operating a facility such as Libby Dam have a direct impact on the environment. Our goal is to operate Libby Dam to minimize negative impacts on the environment through pollution prevention and mitigation, and we are committed to continual improvement.  Our commitment is to comply with environmental legislation, rules, and regulations. We encourage environmental stewardship at every level throughout the organization.
