Bar G9 #2 dam
Bar G9 #2
Bar G9 #2 is a privately owned earth dam located in Mosby, Montana, along TR-HOME CREEK. Built in 1950 by USDA NRCS, this dam stands at 17 feet high and spans 400 feet in length, providing essential water resources for fire protection, livestock, and small fish ponds in the area. With a storage capacity of 149 acre-feet, the dam serves as a vital infrastructure for the community.
Managed by the DNRC and regulated by the state of Montana, Bar G9 #2 has a low hazard potential and a moderate risk assessment rating. Despite not being rated for condition assessment, the dam is inspected, permitted, and enforced by state agencies, ensuring its structural integrity and safety. The area is represented by Greg Gianforte (R) in Congressional District 00, Montana, highlighting the significance of water resource management in the region.
Water resource and climate enthusiasts will be captivated by the strategic location and purpose of Bar G9 #2, serving as a critical asset for water storage and management in Rosebud County, Montana. With a focus on fire protection, livestock, and small fish pond support, this dam plays a crucial role in sustaining the local ecosystem and providing essential water resources for the community. Its low hazard potential and moderate risk assessment underscore the importance of ongoing monitoring and management to ensure the long-term viability of this vital infrastructure.

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 Bar G9 #2
Where does the data for Bar G9 #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.
