Summary
With a height of 26 feet and a storage capacity of 65 acre-feet, this earth dam serves the primary purpose of providing water for irrigation in the surrounding area. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and is inspected regularly to ensure its safety and functionality.
Situated in a low hazard potential area, the Bonhomme Dam has not been rated for its condition assessment, but continues to reliably serve its intended purpose. Although not under the jurisdiction of a federal agency, the dam's construction, operation, and enforcement are overseen by state regulatory agencies. Despite its age, the dam has not required any modifications and remains a key component of the local water resource infrastructure.
Water resource and climate enthusiasts may find the Bonhomme Dam an intriguing example of a privately owned irrigation structure that has stood the test of time. Its location in a picturesque setting in Park County, Montana, coupled with its functional design and efficient operation, make it a notable feature in the management of water resources in the 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.
