Summary
Built in 1964, this dam stands at 20 feet high and spans 150 feet in length, with a storage capacity of 62 acre-feet. It primarily serves the purposes of fire protection, stock, and small fish pond management in the region. The dam is regulated by the Montana Department of Natural Resources and Conservation (DNRC) and undergoes regular inspections, enforcement, and permitting to ensure its safety and compliance with state regulations.
With a low hazard potential and a current condition assessment of "Not Rated," Smith Ranch 4 is categorized as a structurally sound and well-maintained water resource infrastructure. Although not rated for emergency action planning or inundation mapping, this dam remains a vital asset for water management in the Garfield County area. Located in Congressional District 00 of Montana, Smith Ranch 4 is under the jurisdiction of the Omaha District of the US Army Corps of Engineers, providing further oversight and support for its operations.
Overall, Smith Ranch 4 stands as a crucial piece of infrastructure for water resource management in Montana, offering essential services for fire protection, livestock, and fisheries while maintaining a low risk profile. As a privately owned dam with state regulation and oversight, its role in ensuring water security and environmental stewardship in the region is significant. With its strategic location and reliable operations, Smith Ranch 4 continues to play a vital role in sustaining water resources and climate resilience in the area.

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.
