Mable #2 dam
Mable #2
Mable #2 is a private earth dam located in Phillips County, Montana, along the TR-Coburn Coulee river. Completed in 1960, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 12 feet and a storage capacity of 174 acre-feet, Mable #2 plays a crucial role in water resource management in the area. Despite its low hazard potential, the dam has not been rated for its condition and lacks regular inspections.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Mable #2 is subject to state regulations and inspections to ensure its safety and functionality. Located within Congressional District 00, Montana, the dam is overseen by Congressman Greg Gianforte (R) and falls under the jurisdiction of the state regulatory agency. While the dam has not been modified in recent years and lacks detailed risk assessment and emergency preparedness plans, it remains a vital infrastructure for water supply and agricultural activities in the region.
Enthusiasts of water resources and climate change will find Mable #2 to be an interesting case study of a privately owned dam with multiple purposes and a history dating back to the 1960s. With its location in a rural area and limited hazard potential, the dam presents opportunities for further research on its condition, risk management measures, and potential impacts of climate change on its operation. As water scarcity and extreme weather events become more prevalent, understanding the role of dams like Mable #2 in sustainable water management is crucial for ensuring the resilience of local communities and ecosystems.

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 Mable #2
Where does the data for Mable #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.
