Summary
Built in 1953, this earth dam serves multiple purposes including fire protection, stock watering, and small fish pond creation. With a height of 30 feet and a length of 350 feet, Smile #2 has a storage capacity of 309 acre-feet, with a normal storage level of 158 acre-feet. The dam is regulated and inspected by the Montana Department of Natural Resources and Conservation (DNRC), ensuring its safety and compliance with state regulations.
Despite being classified with a low hazard potential, Smile #2 has not been rated for its condition assessment. The dam does not have an Emergency Action Plan (EAP) prepared, and there are no known risk assessment or management measures in place. The structure has not been modified in recent years and its last inspection date, as well as other critical information like emergency contacts and inundation maps, remain unknown. The dam's location in Dawson County, Montana, makes it an important water resource for the local community, emphasizing the need for proper monitoring and maintenance to ensure its continued safety and functionality for fire protection and other purposes.

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.
