Summary
This dam, situated on Antelope Flat Creek, serves multiple purposes including fire protection, stock, and small fish pond. With a dam height of 13 feet and a length of 500 feet, Leepin'Antelope has a storage capacity of 89 acre-feet and a drainage area of 4.69 square miles.
Managed by the DNRC, this low hazard potential dam is state regulated and inspected, ensuring its safety and compliance with regulations. Despite its age, Leepin'Antelope remains in good condition with a not yet rated condition assessment. The dam's emergency action plan status, risk assessment, and management measures are currently undisclosed, reflecting a need for further information on its preparedness and response capabilities in case of emergencies.
For water resource and climate enthusiasts, Leepin'Antelope presents an intriguing case study of a historic earth dam that continues to fulfill vital functions in the region. Its location, design, and regulatory oversight offer valuable insights into the intersection of water management, infrastructure development, and environmental stewardship in Montana. Further exploration of Leepin'Antelope's operational details and risk management strategies can provide a deeper understanding of the challenges and opportunities in maintaining aging dams for the benefit of local communities and ecosystems.

Dam Data Reference
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.
