Jardee dam
Jardee
Jardee is a privately owned irrigation dam located in Carter County, Montana, along Horse Creek. Built in 1966 by the USDA NRCS, this earth dam stands at a height of 20 feet and spans 580 feet in length. With a storage capacity of 165 acre-feet, it primarily serves the purpose of irrigation for the surrounding agricultural lands. Managed by the DNRC, Jardee is regulated, inspected, and enforced by state authorities to ensure its safety and functionality.
Despite being categorized with a low hazard potential, Jardee has not been formally rated for its condition assessment. The dam has a spillway width of 100 feet and a maximum discharge rate of 800 cubic feet per second. While it does not have any associated locks or outlets, it plays a crucial role in water resource management in the region. Although the emergency action plan status and risk assessment details are currently unavailable, the dam remains a key infrastructure for supporting the local agricultural community and maintaining water resources along Horse Creek.
Situated in a strategic location with Congressman Greg Gianforte representing the area, Jardee serves as a vital link in the water distribution network in Montana. As part of the Omaha District under the USACE, it plays a crucial role in ensuring water availability for irrigation purposes and contributes to the overall water security in the region. With its unique design and historical significance, Jardee stands as a testament to the importance of water resource management and climate resilience efforts in Montana.

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 Jardee
Where does the data for Jardee 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.
