Two Dollar Bill dam
Two Dollar Bill
Two Dollar Bill is a privately owned dam located in Meagher County, Montana, along Sixteenmile Creek. Built in 1940, this earth dam stands at a height of 15 feet and has a storage capacity of 77 acre-feet, primarily used for fire protection, stock, and small fish pond purposes. Despite being regulated by the Montana Department of Natural Resources and Conservation, the dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Situated in a picturesque rural setting, Two Dollar Bill serves as a vital resource for the local community, providing essential water storage for various purposes. While the dam has not been recently inspected or assessed, its historical significance and functional role in the area make it an interesting subject for water resource and climate enthusiasts. With its tranquil surroundings and unique purpose, this dam offers a glimpse into the intersection of human activity and nature in Montana's landscape.
As an earth dam with a relatively low hazard potential, Two Dollar Bill may not be as high-profile as other structures, but its contribution to fire protection, livestock management, and recreational fishing highlights the diverse roles that dams play in sustaining local ecosystems and communities. With its historical construction and ongoing regulatory oversight, this dam serves as a reminder of the importance of responsible dam management and the need to balance human needs with environmental considerations in water resource management.

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 Two Dollar Bill
Where does the data for Two Dollar Bill 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.
