Summary
Built in 1960, this earth dam stands at a height of 24 feet and has a storage capacity of 98 acre-feet, primarily serving purposes such as fire protection, stock, and small fish pond. With a low hazard potential and a condition assessment of 'Not Rated', this dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is subject to state inspection and enforcement.
Situated in Custer County, Montana, French #12 is owned privately and falls under the jurisdiction of the state, with regulatory oversight from the DNRC. The dam's primary purpose is to provide essential services like fire protection and livestock watering, while also supporting recreational activities such as fishing in the small pond created by its reservoir. Despite its age, French #12 has not been assigned a condition rating and lacks detailed risk management measures.
Although French #12 has not been rated for its condition, it boasts a stable hazard potential and is considered a crucial asset for water storage and conservation in the region. While lacking detailed information on its risk assessment and emergency action plan, this dam remains an integral part of the local water resource infrastructure, contributing to the resilience of the community and supporting various essential functions.

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.
