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.

Flow Update

 August 13, 2018

Current Koocanusa Reservoir elevation: 2446.9 feet
Current Koocanusa Reservoir inflow: ~6 kcfs
Current Libby Dam outflow: 9 kcfs
Current Kootenai River elevation at Bonners Ferry: 1747.2 feet

Libby Dam outflow will remain at the bull trout minimum flow, 9 kcfs, through the end of August. Based on current projections, the elevation of Lake Koocanusa is expected to decrease by 3-4 feet during August, due to declining inflows.
