Graber #2 dam
Graber #2
Graber #2, located in Fergus County, Montana, is a privately owned earth dam constructed in 1958 by the USDA NRCS for multiple purposes, including fire protection, stock water, and small fish pond. 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.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Graber #2
Where does the data for Graber #2 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
