Summary
Built in 1972 by the USDA NRCS, the earth dam stands at 29 feet high with a length of 250 feet, providing a storage capacity of 103 acre-feet. Located on Freddie Creek, Griffin is regulated by the DNRC and falls under state jurisdiction for permitting, inspection, and enforcement.
With a low hazard potential and a condition assessment of "Not Rated," Griffin remains a vital resource for the local community. The dam's primary purpose of fire protection highlights its importance in safeguarding against wildfires in the region. The structure's last inspection date and assessment of emergency preparedness are pending, indicating a need for ongoing monitoring and risk management measures.
As a key component of the water infrastructure in Custer County, Montana, Griffin plays a crucial role in water resource management and conservation efforts. With its strategic location and multi-functional design, this earth dam stands as a testament to the collaboration between private owners and government agencies in ensuring the sustainability of water resources in the region.

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.
