Summary
Built in 1950, Penny stands at a height of 24 feet and has a storage capacity of 7678 acre-feet, primarily used for irrigation purposes. Situated in the Belltower area, Penny is regulated by the Montana Department of Natural Resources and Conservation, ensuring proper inspection, enforcement, and permitting.
The dam's significant hazard potential highlights the importance of proactive risk management and emergency preparedness. While Penny's condition assessment is currently "Not Rated," its operational status and compliance with safety guidelines remain crucial for the surrounding community. Despite lacking specific details on inspection frequency and emergency action plans, Penny's location and purpose underscore the vital role it plays in water resource management in the region.
With its earth dam type and historical significance, Penny serves as a key infrastructure for water storage and distribution in the area. As a focal point for irrigation activities, Penny's maintenance and upkeep are essential to ensuring sustainable water resource management for agricultural needs. As water resource and climate enthusiasts, understanding the intricacies of Penny's design, ownership, and regulatory oversight sheds light on the intersection of human infrastructure and natural ecosystems 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.
