Summary
Built in 1960, this private earth dam stands at a height of 12 feet and has a storage capacity of 151 acre-feet. Situated on the Dugout Coulee, this dam is state-regulated and inspected, with low hazard potential, making it a vital resource for the local community.
Despite its small size, Smart Mans Dam plays a crucial role in water resource management in Chouteau County. With a normal storage capacity of 45 acre-feet, the dam helps mitigate the risk of wildfires, provides water for livestock, and supports local fisheries. The dam's low hazard potential and state jurisdiction ensure its safe operation and maintenance for the benefit of the surrounding area.
As a key feature in the local water infrastructure, Smart Mans Dam contributes to the sustainable management of water resources in Montana. With its strategic location and multi-purpose functionality, this dam exemplifies the importance of small-scale water projects in meeting the diverse needs of rural communities while ensuring environmental and climate resilience.

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.
