Summary
Built in 1953, this earth dam stands at 38 feet high and spans 225 feet in length, with a storage capacity of 183 acre-feet. The primary purposes of the dam are for fire protection, stock, and a small fish pond, serving the local community in Powder River.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Giacometto #1 is classified as a significant hazard potential structure but has not been rated for its condition assessment. Despite the lack of recent inspections and assessments, the dam is state-regulated and permitted, with regular inspections and enforcement measures in place to ensure its safety and functionality. With its location in a remote area and its importance for fire protection and water storage, Giacometto #1 plays a crucial role in the local water resource management and climate resilience efforts in Powder River, Montana.
As a key infrastructure for water management and emergency preparedness in the region, Giacometto #1 represents the intersection of human-nature interactions in the face of changing climate conditions. With its history dating back to the 1950s and its continued relevance for fire protection and stock water supply, the dam serves as a reminder of the importance of sustainable water resource management and infrastructure maintenance in the context of climate change. As water enthusiasts and climate advocates, understanding the role of dams like Giacometto #1 is crucial for promoting resilience and adaptation strategies in the face of evolving environmental challenges.

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.
