Summary
Built in 1920, this earth dam reservoir stands at a height of 15 feet and has a storage capacity of 162 acre-feet, primarily serving as a fire protection, stock, and small fish pond. With a low hazard potential, it is regulated and inspected by the state, ensuring its safety and functionality.
Situated along the TR-Horse Corral Coulee, Battle Horse Reservoir covers an area of 83 acres and is used for various purposes including fire protection and recreational activities. Despite being not rated for its condition assessment, the reservoir remains a vital water source in the region. With Congressman Greg Gianforte representing the Congressional District of Montana, the reservoir plays a crucial role in the local community's water management and conservation efforts.
The reservoir's location in Blaine County, Montana, makes it a key feature in the region's water infrastructure. Although not operated by the US Army Corps of Engineers, Battle Horse Reservoir contributes to the overall water supply and resource management in the area. As a focal point for water resource and climate enthusiasts, this reservoir serves as a reminder of the importance of sustainable water management practices in the face of changing climate patterns.

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.
