Hamen Reservoir dam
Hamen Reservoir
Hamen Reservoir, located in Meagher, Montana, is a privately owned water source primarily used for fire protection, stock watering, and as a small fish pond. Built in 1945, this earth dam stands at a height of 22 feet and has a storage capacity of 231 acre-feet. The reservoir covers a surface area of 26 acres and is situated along the TR-Durst Creek, approximately 7 miles from Ringling. Despite its low hazard potential, the dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular inspections, enforcement, and permitting to ensure its safety and compliance.
With its picturesque location and important role in supporting local water needs, Hamen Reservoir serves as a vital resource for the surrounding community. The reservoir's association with fire protection highlights its significance in safeguarding the area from potential wildfires, while also providing water for livestock and recreational fishing. The dam's condition is currently not rated, but its low hazard potential suggests a stable and secure structure that continues to meet the needs of its owners and stakeholders.
As an integral part of the water infrastructure in Meagher County, Hamen Reservoir contributes to the resilience of the region's water resources and climate adaptation efforts. With its historic significance dating back to the mid-20th century, the reservoir represents a sustainable and essential asset for water storage and management. As water resource and climate enthusiasts, exploring the unique features and functions of Hamen Reservoir offers valuable insights into the intersection of human ingenuity and environmental stewardship in maintaining a reliable and resilient water supply 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 Hamen Reservoir
Where does the data for Hamen Reservoir 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.
