Summary
Completed in 2006, this dam stands at a height of 30 feet and has a storage capacity of 18.4 acre-feet, making it a vital structure for managing water resources in the area. With a low hazard potential and a moderate risk assessment rating, the Smith Dam plays a crucial role in mitigating potential risks and ensuring the safety of the surrounding community.
The dam features an uncontrolled spillway and outlet gates, with a maximum discharge rate of 50.2 cubic feet per second. Although not currently regulated by the state, the Smith Dam serves as a key infrastructure for flood control and water management in the region. Despite its relatively small surface area of 1 acre, the dam plays a significant role in regulating the flow of water and protecting downstream areas from potential flooding events.
While the Smith Dam has not been inspected or rated for condition assessment, its design and construction by the Natural Resources Conservation Service reflect a commitment to sustainable water resource management. With its strategic location and contribution to grade stabilization along the TR-Medicine Creek, the Smith Dam stands as a testament to the importance of infrastructure in mitigating climate-related risks and ensuring the resilience of water resources in Missouri.

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.
