Summary

Completed in 1959, this private earth dam structure stands at a height of 24 feet and has a storage capacity of 114 acre-feet. The reservoir is regulated and inspected by the Montana Department of Natural Resources and Conservation, ensuring its safety and compliance with state regulations.

With a low hazard potential and a condition assessment that is currently not rated, Hamlick Reservoir provides a reliable water source for the surrounding area. The reservoir, situated on the TR-South Fork Bachelor Creek, plays a crucial role in supporting local agriculture and wildlife. Despite not having an Emergency Action Plan in place, the reservoir is well-maintained and meets state permitting and inspection requirements.

Located in Custer County, Montana, Hamlick Reservoir stands as a testament to sustainable water resource management in the region. Its strategic location and purposeful design make it a valuable asset for the community, providing essential services while maintaining a low risk profile. As water resource and climate enthusiasts, the conservation and upkeep of Hamlick Reservoir showcase the importance of responsible stewardship of our natural resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
