Jonquil dam
Jonquil
Jonquil is a private water resource located in Teton, Montana, with a primary purpose of fire protection, stock, or small fish pond. The earth dam, completed in 1938, stands at a height of 15 feet and has a storage capacity of 67 acre-feet. Situated along the TR-BRUCE COULEE, Jonquil plays a crucial role in providing water for fire protection and supporting local livestock operations.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Jonquil is regulated and inspected regularly to ensure its safety and functionality. Despite being rated as having low hazard potential and not yet assessed for condition, Jonquil remains an essential resource for the community of CORDOVA. With its historical significance dating back to the 1930s, this water infrastructure continues to support the surrounding area's water needs while contributing to the conservation of natural resources.
As an earth dam with a focus on multiple purposes, including fire protection and stock supply, Jonquil showcases the intersection of water resource management and climate resilience. Its location within the Congressional District 00 of Montana, under the representation of Greg Gianforte, highlights the importance of sustainable water infrastructure in supporting local communities and ecosystems. With a long history of service and a commitment to regulatory compliance, Jonquil stands as a testament to the vital role that water resources play in mitigating climate-related challenges and promoting environmental stewardship.
Dam data reference
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 Jonquil
Where does the data for Jonquil 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.
