Ghost #6 dam
Ghost #6
Ghost #6 is a privately owned earth dam located in Nashua, Montana, along the TR-East Fork Snow Coulee river. Completed in 1966, this dam serves a primary purpose of "Other" with a storage capacity of 101 acre-feet and a maximum height of 15 feet. The dam's low hazard potential and "Not Rated" condition assessment indicate a relatively stable structure in terms of safety and integrity.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Ghost #6 is subject to state regulation, permitting, inspection, and enforcement. Despite its modest size and purpose, this dam plays a crucial role in water resource management and climate resilience in the region. With a normalized storage capacity of 40 acre-feet, Ghost #6 contributes to the local ecosystem and water supply, highlighting the interconnectedness of water resources and climate adaptation efforts.
As part of the broader network of dams and water infrastructure in Montana, Ghost #6 underscores the importance of monitoring and maintaining these structures to ensure their long-term functionality and safety. With its unique location and design, this earth dam stands as a testament to the ongoing efforts to balance water resource management with environmental sustainability and climate resilience in the face of changing weather patterns and hydrological conditions.

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 Ghost #6
Where does the data for Ghost #6 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.
