Fr Dam dam
Fr Dam
Fr Dam, located in Nashua, Montana, is a gravity dam that was completed in 2003 for the primary purpose of creating a Fish and Wildlife Pond. Managed by the Bureau of Land Management, this federal-owned structure stands at a structural height of 34 feet and has a hydraulic height of 29 feet, impounding a maximum storage capacity of 88.21 acre-feet. The dam spans 807 feet in length and covers a surface area of 15.34 acres, serving as a vital resource for the local ecosystem.
Despite being classified as having a low hazard potential, Fr Dam undergoes regular inspections every five years to ensure its structural integrity and safety. The last recorded inspection was on July 22, 2020, with a condition assessment of "Not Rated." While no emergency action plan (EAP) is currently in place, the dam has not experienced any modifications since its completion, highlighting its stable and reliable nature in contributing to water resource management and climate resilience efforts in the region.
With its strategic location on Bullwhacker Coulee and contribution to fish and wildlife habitat enhancement, Fr Dam serves as a valuable asset for the community and ecosystem in Blaine County, Montana. As a federal-owned structure designed and constructed by the Bureau of Land Management, this gravity dam embodies a harmonious balance between water resource management, environmental conservation, and recreational opportunities, showcasing the importance of sustainable infrastructure in adapting to changing climate conditions and promoting biodiversity in the area.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Fr Dam
Where does the data for Fr Dam 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.
