Summary
Built in 1959, this earth dam structure stands at a height of 12 feet and has a storage capacity of 75 acre-feet. The lagoon is owned and regulated by the local government, with oversight from the Montana Department of Natural Resources and Conservation (DNRC).
Despite its low hazard potential, the Cut Bank Sewage Lagoon plays a vital role in protecting water resources and public health in the area. It is regularly inspected, permitted, and enforced to ensure compliance with state regulations. The facility serves as an example of responsible wastewater management and highlights the importance of infrastructure investments in safeguarding our environment and communities from the impacts of climate change.
Located in the Old Maids Coulee watershed, the Cut Bank Sewage Lagoon is a testament to the collaborative efforts between local and state agencies to address water quality challenges. As climate enthusiasts, it is essential to recognize and support the maintenance and improvement of critical infrastructure like this lagoon to adapt to changing environmental conditions and ensure the sustainable use of water resources for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
