Summary
Completed in 1960, this earth dam stands at a height of 30 feet and has a storage capacity of 114 acre-feet, with a normal storage level of 66 acre-feet. Situated on the TR-East Fork Cherry Creek, Allie is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected, permitted, and enforced by state authorities.
With a significant hazard potential and a condition assessment that is yet to be rated, Allie serves as a crucial infrastructure for water resource management in the region. Its location in the city of Glasgow, within the jurisdiction of the state of Montana, highlights its importance in providing essential services for fire protection and livestock watering. Despite lacking detailed risk assessment and management measures, the dam's presence underscores the need for continuous monitoring and maintenance to ensure its structural integrity and overall safety.
As a key component in the water resource network, Allie plays a vital role in sustaining the local ecosystem and supporting various activities in the area. With a history dating back to the 1960s, this dam symbolizes the intersection of human intervention and natural systems, emphasizing the importance of responsible stewardship and proactive measures to address potential risks and challenges posed by climate change and evolving water resource dynamics.

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.
