Libby Dam

Libby Dam Project is a multi-purpose water resource development. Its purposes are flood reduction, hydropower, recreation, and environmental stewardship.

We recognize our day-to-day activities, in operating a facility like 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 and to comply with environmental legislation, rules, and regulations.

We encourage environmental stewardship at every level throughout the organization.
