Norman #2 dam
Norman #2
Norman #2 is a privately owned earth dam located in Fergus County, Montana, designed for fire protection, stock, or small fish pond purposes. Completed in 1999, this dam stands at a height of 26.5 feet and has a storage capacity of 122 acre-feet, with a normal storage level of 86.3 acre-feet. Situated on Plum Creek, this structure covers a surface area of 9.5 acres and serves as a vital resource for water management in the region.
With its low hazard potential and moderate risk assessment, Norman #2 plays a crucial role in ensuring water security and fire protection in the area. The dam, regulated by the Montana Department of Natural Resources and Conservation (DNRC), undergoes state inspections, permitting, and enforcement to maintain its structural integrity and safety standards. Despite its uncontrolled spillway type, the dam has not been rated for its overall condition, emphasizing the need for continued monitoring and risk management measures to safeguard this essential water resource.
For water resource and climate enthusiasts, Norman #2 offers a compelling example of how private infrastructure can contribute to environmental sustainability and community resilience. As a key player in water storage and management on Plum Creek, this dam underscores the importance of proactive risk assessment and emergency preparedness to mitigate potential hazards and ensure the long-term viability of water resources in the region. By staying informed and engaged with initiatives like the Emergency Action Plan (EAP) and risk management measures, stakeholders can help support the resilience of structures like Norman #2 and promote sustainable water practices for generations to come.

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 Norman #2
Where does the data for Norman #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.
