Summary
The dam has a storage capacity of 1847.69 acre-feet and a surface area of 251.9 acres, serving the purpose of regulating an intermittent river or stream in the area. Despite being a low hazard potential structure, the dam has not been rated for its condition assessment.
Owned, funded, designed, constructed, regulated, inspected, and operated by the Bureau of Land Management, Wild Horse Dam Pd plays a crucial role in water resource management in the region. With no state jurisdiction or permitting requirements, the dam stands as a federal entity ensuring the safe regulation of water flow and storage. Although the dam has not been modified in recent years and lacks an Emergency Action Plan (EAP), its low hazard potential indicates a relatively stable and secure structure.
Given its federal ownership and operation, Wild Horse Dam Pd stands as a testament to the collaboration and commitment of the Bureau of Land Management in ensuring water resource management and climate resilience in Montana. As a key infrastructure for the region, the dam's presence underscores the importance of maintaining and monitoring such structures to mitigate potential risks and ensure the safety of surrounding communities and ecosystems. With its low hazard potential and unlisted condition assessment, efforts to assess and address any vulnerabilities in the dam's structure and operations may be necessary to uphold its functionality and resilience in the face of evolving climate 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.
