Summary
Built in 1949 for fire protection, stock, and small fish pond purposes, the dam stands at a height of 22 feet and has a length of 430 feet. With a storage capacity of 57 acre-feet and a surface area of 5 acres, the dam serves as a vital resource for the local community.
The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and has a low hazard potential with a moderate risk assessment rating of 3. The spillway, which is uncontrolled, has a width of 60 feet. Although the dam's condition is not rated, inspections are conducted periodically to ensure its safety and functionality. With its importance for fire protection and agricultural purposes, Jones #1 plays a crucial role in the water resource management of the area.
Overall, Jones #1 represents a significant water infrastructure in Custer County, Montana, providing essential services for fire protection, livestock, and recreational activities. As a privately owned structure, the dam is subject to state regulations and inspections to ensure its reliability and safety. With its historical significance and ongoing importance for the community, Jones #1 serves as a valuable asset in the management of water resources and climate resilience in the region.

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.
