Summary
Built in 1960, this earthen dam stands at a height of 10 feet and spans 200 feet in length, providing essential functions for fire protection, livestock, and small fish pond purposes. With a storage capacity of 57 acre-feet, Peigneux serves as a crucial resource for water management in the region.
Despite its low hazard potential and current "Not Rated" condition assessment, Peigneux is regulated by the Montana Department of Natural Resources and Conservation (DNRC), ensuring that it meets state permitting, inspection, and enforcement standards. As a key structure in the area, the dam plays a vital role in water resource management and contributes to the overall resilience of the local ecosystem. With its location in a scenic and environmentally significant area, Peigneux serves as a valuable asset for water resource and climate enthusiasts interested in sustainable water infrastructure.
As a part of the Omaha District in Congressional District 00, Montana, Peigneux represents a prime example of responsible water management practices and the importance of maintaining infrastructure for multiple beneficial uses. From its modest size and purpose to its state-regulated status and favorable risk profile, Peigneux stands as a noteworthy site for those passionate about water resource management and climate adaptation efforts in 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.
