Summary
This private earth dam, completed in 1955, stands at 21 feet tall and has a storage capacity of 119 acre-feet. The dam plays a vital role in the local ecosystem and community by providing essential water resources for various uses while maintaining a low hazard potential.
Managed by the DNRC and regulated by the state of Montana, Lockie #10 is subject to regular inspections, permitting, and enforcement to ensure its structural integrity and compliance with safety standards. Despite its age, the dam's condition remains unrated, highlighting the need for ongoing assessment and maintenance to mitigate any potential risks. With a location in Miles City, Custer County, this dam contributes to the region's water management efforts and underscores the importance of sustainable resource utilization in the face of changing climates.
As a key component of the local water infrastructure, Lockie #10 plays a crucial role in water conservation and management in the area. Its historical significance, combined with its current operational status, underscores the importance of maintaining and monitoring dams to ensure their continued functionality and safety. For water resource and climate enthusiasts, this structure offers a tangible example of the intersection between human intervention and natural ecosystems, showcasing the delicate balance required to sustainably manage water resources in the face of evolving environmental challenges.

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.
