Summary
#1 is a privately owned earth dam located in Miles City, Montana, along the TR-East Fork Ash Creek. Completed in 1972, this dam serves multiple purposes including fire protection, stock, and a small fish pond, with a primary height of 20 feet and a storage capacity of 61 acre-feet. Its low hazard potential and "Not Rated" condition assessment indicate its stable and safe structure.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Barta, A.J. #1 is regulated, permitted, inspected, and enforced by the state, ensuring its compliance with safety and environmental standards. The dam's location in a rural area and its modest size make it a valuable resource for local water management and wildlife habitat. With a maximum discharge of 215 cubic feet per second, this dam plays a crucial role in maintaining water supply and protecting against potential emergencies.
Overall, Barta, A.J. #1 stands as a vital infrastructure for water resource management in Custer County, Montana, providing essential services for fire protection, livestock, and aquatic life. Its significance lies in its multi-purpose functionality, state regulation, and low-risk profile, making it a valuable asset in the region's water and climate resilience efforts.

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.
