Summary
This sewage lagoon, constructed in 1959, serves as a crucial infrastructure for wastewater treatment in the area. With a capacity of 400 acre-feet, the lagoon plays a significant role in maintaining water quality and protecting the environment along the TR-Missouri River.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), the Wolf Point Sewage Lagoon is subject to state regulations and regular inspections to ensure its effectiveness and compliance with safety standards. With a low hazard potential and a current "Not Rated" condition assessment, the lagoon poses minimal risks to the surrounding community. While no emergency action plan (EAP) is currently in place, the lagoon's operations continue to meet guidelines and serve the local population in a sustainable and responsible manner.
As water resource and climate enthusiasts continue to advocate for the protection and preservation of our natural environment, the Wolf Point Sewage Lagoon stands as a testament to responsible water management practices in rural Montana. With its earth dam structure and a history of serving the community for over six decades, the lagoon remains an essential component of the local water infrastructure, contributing to the overall health and well-being of the region.

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.
