Summary
With a height of 39 feet and a length of 3168 feet, this dam has a storage capacity of 479 acre-feet, providing essential water resources for the surrounding area. Situated on TR-South Fork Bear Creek, Graber #2 is regulated by the Montana DNRC and undergoes regular inspections and enforcement to ensure its safety and functionality.
Despite being classified as a low hazard potential structure, Graber #2 has not been rated for its current condition. The dam's emergency action plan (EAP) status is unknown, with important details like the last inspection date, condition assessment, and risk assessment still pending. It is crucial for water resource and climate enthusiasts to monitor the condition of Graber #2 closely to ensure its continued effectiveness in providing water for fire protection, livestock, and small fish pond purposes. With potential risks associated with dam failure, having a comprehensive EAP and regular maintenance checks are essential to safeguard the surrounding community and environment.
Although Graber #2 has not been updated or inspected recently, its role in providing water resources for its designated purposes underscores the importance of proper dam maintenance and monitoring. As a key infrastructure in Fergus County, Montana, this earth dam serves as a crucial resource for the local community and wildlife. Continued oversight and proactive measures are necessary to mitigate potential risks and ensure the long-term functionality and safety of Graber #2 for future generations.

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.
