About this dam

Oscar #1

Located in Fallon, Montana, Oscar #1 is a privately owned earth dam constructed in 1959 by the USDA NRCS for fire protection, stock, and small fish pond purposes. With a height of 12 feet and a length of 200 feet, the dam has a storage capacity of 84 acre-feet and serves the TR-Sandstone Creek. Managed by the DNRC, the dam is regulated and inspected by the state to ensure its safety and compliance with regulations.

Despite its low hazard potential, Oscar #1 plays a crucial role in water resource management in the area, providing essential storage for agricultural and recreational purposes. The dam's location in PLEVNA, Montana, makes it a vital asset for the community, offering protection against fires and supporting local wildlife. With no associated structures and a history of state enforcement and inspection, Oscar #1 stands as a testament to responsible water resource management and collaboration between private owners and regulatory agencies.

As climate change continues to impact water resources, dams like Oscar #1 become increasingly important for maintaining water security and resilience in the face of changing conditions. By adhering to state permitting and inspection requirements, the dam ensures its continued functionality and safety, highlighting the critical role of infrastructure in adapting to a changing climate. With its storied history and commitment to water management, Oscar #1 serves as a beacon of sustainable resource utilization in the Montana landscape.

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.

FAQ

About Oscar #1

Where does the data for Oscar #1 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.
