Summary
Built in 1950, this earth dam stands at 10 feet tall and spans 200 feet in length, providing a storage capacity of 54 acre-feet. The dam is regulated and permitted by the Montana Department of Natural Resources and Conservation, ensuring compliance with state regulations and regular inspections to maintain its low hazard potential.
With a primary purpose of safeguarding against wildfires and supporting local agricultural activities, the Jack of Hearts reservoir plays a vital role in water resource management in Carter County, Montana. Situated on TR-Short Creek within the jurisdiction of the state, this privately-owned dam is essential for maintaining water supply and protecting the surrounding environment. Despite its low hazard potential, the dam's condition remains unrated, highlighting the need for ongoing monitoring and potential risk management measures to ensure its continued safety and functionality for years to come.
As a key component of the local water infrastructure, the Jack of Hearts reservoir provides a crucial lifeline for residents and wildlife in the area. With its strategic location and multi-purpose design, this earth dam stands as a testament to the importance of sustainable water resource management and climate resilience in the face of changing environmental conditions.

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.
