Summary
Constructed in 1954 by the USDA NRCS, Antares stands at 30 feet high and has a storage capacity of 92 acre-feet, with a normal storage level of 60 acre-feet. The dam spans 300 feet in length and is primarily used for irrigation purposes in the area.
Managed by the DNRC, Antares is regulated and inspected by the state of Montana to ensure its safety and functionality. With a low hazard potential and a condition assessment of "Not Rated," the dam serves as a vital water resource for the surrounding agricultural community. Although not rated for emergency preparedness, the dam is continuously monitored to meet state regulatory standards and ensure its operational efficiency.
Antares, situated in a picturesque location in Congressional District 00, Montana, plays a crucial role in water management and irrigation in the region. As a key structure in the area, the dam contributes to the sustainability of the local ecosystem and supports the agricultural activities that depend on its water supply. With its historical significance and ongoing state oversight, Antares remains an important landmark for water resource and climate enthusiasts in Montana.

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.
