Summary
Built in 1943, this earth dam stands at a height of 25 feet and has a length of 900 feet, providing fire protection and serving as a stock or small fish pond. With a storage capacity of 193 acre-feet, Angie plays a crucial role in water resource management in the area, especially for fire protection purposes.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Angie is regulated, permitted, inspected, and enforced by the state. Although its condition assessment is not rated, the dam is considered to have significant hazard potential. Despite not having an Emergency Action Plan (EAP) in place, Angie continues to meet guidelines for operation and maintenance. Its role in providing essential water resources for the community highlights the importance of proper management and upkeep to ensure the safety and sustainability of the surrounding environment.
Located in McCone County, Montana, Angie's presence is significant for the local community as it serves multiple purposes, including fire protection and water storage. With its historical significance dating back to 1943, Angie stands as a testament to the importance of water resource infrastructure in the region. As climate change continues to impact water availability and management, the proper maintenance and regulation of dams like Angie become increasingly vital for ensuring water security and resilience in the face of changing environmental conditions.

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.
