Summary
This Earth dam stands at a height of 24 feet and has a storage capacity of 378 acre-feet, primarily used for irrigation purposes. The reservoir is situated along the Sand Butte Coulee and is regulated by the state agency DNRC, with regular inspections and enforcement to ensure its safety and compliance with state regulations.
With a significant hazard potential, Barley Reservoir plays a crucial role in supporting agricultural activities in the region, providing water for irrigation to help sustain the local farming community. The reservoir's location in the heart of Montana's countryside and its close proximity to Thurlow make it a vital water resource for the area. Despite not being rated for condition assessment, the reservoir continues to serve its purpose effectively, with no reported modifications or major incidents over the years.
As a key infrastructure in the area, Barley Reservoir contributes to the overall water management and climate resilience efforts in Montana. Its presence along the Sand Butte Coulee and its strategic design by the USDA NRCS demonstrate a commitment to sustainable water resource utilization for agricultural needs. With its significant storage capacity and state-regulated operations, the reservoir stands as a testament to responsible water management practices in the region, supporting the local economy and environmental sustainability.

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.
