Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
