Summary
The earth dam, completed in 1945, has a height of 15 feet and a length of 500 feet, providing a storage capacity of 62 acre-feet. This low hazard potential structure is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is regularly inspected for safety and compliance.
Situated along TR-Moran Creek, Middle Axoloil Lake #2 serves as a crucial water source for the surrounding area, offering irrigation for livestock, fire protection, and recreational fishing opportunities. The dam's normal storage capacity of 32 acre-feet supports a diverse ecosystem and contributes to the overall water management efforts in the region. Despite being privately owned, the structure falls under state jurisdiction and is subject to state permitting, inspection, and enforcement protocols.
With its strategic location in Congressional District 00, Montana, Middle Axoloil Lake #2 plays a vital role in water management and resource conservation efforts. As a well-maintained and regulated water source, this earth dam exemplifies the importance of sustainable infrastructure for both human needs and environmental protection. Climate enthusiasts and water resource advocates can appreciate the careful management and maintenance of this essential reservoir in the heart of Big Sky Country.

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.
