Summary
Built in 1954 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and small fish pond management. Situated on TR-SHOTGUN CREEK, Fiesty has a dam height of 17 feet and a storage capacity of 120 acre-feet, providing essential water resources for the surrounding area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Fiesty is regulated, permitted, inspected, and enforced in accordance with state jurisdiction. With a low hazard potential and a condition assessment of 'Not Rated', the dam is currently in stable condition. While the dam has not been assigned a Dam Safety Action Classification (DSAC) date, it meets state guidelines for emergency action plans (EAP) and inundation maps.
Although Fiesty has not been modified in recent years and lacks detailed risk assessment and management measures, it continues to play a crucial role in water resource management and climate resilience efforts in the region. As a key infrastructure for fire protection and agricultural activities, Fiesty highlights the importance of monitoring and maintaining earth dams to ensure the safety and sustainability of water resources in Montana.

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.
