Montana #9 dam
Montana #9
Montana #9 is a state-regulated earth dam located in Rosebud, Montana, along the Butte Creek. Completed in 1958, this dam serves multiple purposes including fire protection, stock, and a small fish pond. With a height of 18 feet and a storage capacity of 58 acre-feet, Montana #9 has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), this dam is inspected, permitted, and enforced by the state regulatory agency. It is designed to withstand hydraulic pressures and ensure the safety of the surrounding community. Although it has not been modified in recent years and lacks detailed risk management measures, Montana #9 stands as an essential structure in the region for water resource management and climate resilience efforts.
For water resource and climate enthusiasts, Montana #9 represents a vital piece of infrastructure that contributes to the overall environmental sustainability and public safety of the area. With its specific purposes and low hazard potential, this earth dam plays a crucial role in providing fire protection, maintaining stock, and supporting local aquatic life. As efforts continue to enhance risk assessment and management strategies, Montana #9 remains a key asset in the state's water resource and climate adaptation initiatives.

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 Montana #9
Where does the data for Montana #9 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.
