Summary
Constructed in 1954, this earth dam stands at a height of 20 feet and has a storage capacity of 234 acre-feet. The primary purpose of Aberta is to provide irrigation water to the surrounding area, with a normal storage level of 99 acre-feet.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Aberta is regulated and inspected by the state, ensuring its safety and compliance with state standards. Despite being rated as having a low hazard potential and not yet assessed for its condition, Aberta plays a crucial role in supporting agricultural activities in the region. With its strategic location and vital function in water resource management, this dam serves as a key infrastructure for sustaining the local ecosystem and economy.
In the event of an emergency, the dam's owners are responsible for implementing an Emergency Action Plan (EAP) to mitigate risks and ensure public safety. While details regarding the EAP's preparation and adherence to guidelines are not specified, the presence of such measures underscores the proactive approach towards safeguarding the surrounding community. As a significant contributor to water resource management in the area, Aberta represents a vital piece of infrastructure that exemplifies the importance of sustainable water usage and climate resilience in Montana.

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.
