Summary
With a height of 22 feet and a storage capacity of 64 acre-feet, this low hazard potential dam plays a crucial role in water management in the region. Regulated by the Montana Department of Natural Resources and Conservation, the dam is subject to regular inspections and enforcement to ensure its safety and functionality.
The dam's primary purpose of irrigation reflects its importance in supporting agricultural activities in the area. Despite being in operation for nearly seven decades, the condition of R Garst #2 is currently rated as "Not Rated," highlighting the need for further assessment and maintenance. The dam's location in a sparsely populated area and its low hazard potential contribute to its relatively low risk profile, but ongoing risk management measures are essential to prevent any potential issues.
With a capacity to store 55 acre-feet of water for irrigation, R Garst #2 serves as a vital water resource in the region, supporting agricultural activities and contributing to the local economy. As climate change continues to impact water availability and quality, the proper management and maintenance of dams like R Garst #2 are crucial to ensuring a sustainable water supply for future generations. Through coordinated efforts between private owners, state agencies, and local communities, the resilience of water infrastructure can be enhanced to adapt to changing environmental conditions and safeguard water resources for years to come.

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.
