Summary
Built in 1928, this Earth-type dam stands at a height of 10 feet with a hydraulic height of 7.5 feet, serving primarily for irrigation purposes on Ashley Creek. With a storage capacity of 27,600 acre-feet, this dam covers a surface area of 2,852 acres, providing essential water resources for the surrounding area.
Managed by the Montana Department of Natural Resources and Conservation (DNRC), Ashley Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. The dam has undergone regular state inspections, with the last inspection conducted in May 2021. Despite its age, Ashley Dam continues to play a crucial role in water management and irrigation in the region, ensuring a stable water supply for agricultural activities and environmental conservation.
Located in Congressional District 00, Montana, Ashley Dam is a testament to the importance of proper water resource management in the face of changing climate conditions. With its historical significance and ongoing state oversight, Ashley Dam stands as a key infrastructure for sustainable water use and conservation efforts in the Flathead region.

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.
