Summary
Completed in 1951, this earth dam stands at a height of 10 feet and has a storage capacity of 471 acre-feet, primarily used for irrigation purposes. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC), with inspections and enforcement in place to ensure its safety and functionality.
Situated in Phillips County, Montana, this dam plays a crucial role in providing water for agricultural irrigation in the region. With a significant hazard potential and a condition assessment that is currently not rated, the Frenchman Irrigation Company #1 represents a vital piece of infrastructure in the area. Although details on emergency action plans and risk management measures are not specified, the dam's presence underscores its importance in water resource management and climate adaptation efforts.
With its proximity to the Milk River and its crucial role in providing irrigation water, the Frenchman Irrigation Company #1 serves as a valuable asset in sustaining agriculture in the region. As part of a larger network of dams and irrigation systems in Montana, this privately owned structure highlights the intersection of water resource management, climate resilience, and regulatory oversight. As stakeholders continue to monitor and assess the dam's condition and potential risks, efforts to maintain and enhance its functionality will be essential in ensuring a reliable water supply for the surrounding community.

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.
