Agnes Bob And Noel dam
Agnes Bob And Noel
Agnes Bob and Noel is a state-owned dam located in Virgelle, Montana, along the TR-Crow Coulee river. Completed in 1957, this earth dam stands at a height of 30 feet and has a storage capacity of 57 acre-feet, primarily serving purposes such as fire protection, stock watering, and creating a small fish pond. 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 functionality. While it has a low hazard potential, the condition of Agnes Bob and Noel has not been officially rated.
Situated in Chouteau County, Montana, Agnes Bob and Noel is managed by the state government and remains under state jurisdiction. The dam's location, at coordinates 47.9155 latitude and -110.3176 longitude, contributes to its importance in providing essential water resources for the local community. Despite having no associated structures and being non-Federal, the dam plays a crucial role in serving the surrounding area for various purposes, highlighting its significance in water resource management and climate resilience efforts.
With its historical significance dating back to over six decades, Agnes Bob and Noel continues to play a vital role in water management in Montana. As a key component of the local infrastructure, the dam's purpose extends beyond fire protection and stock watering to contributing to the overall environmental sustainability in the region. As water resource and climate enthusiasts, the presence of Agnes Bob and Noel serves as a reminder of the essential role that dams play in supporting communities and ecosystems, highlighting the need for continued monitoring and maintenance to ensure their long-term functionality and safety.

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 Agnes Bob And Noel
Where does the data for Agnes Bob And Noel 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.
