Summary

Smyth in 1975 for recreational purposes. The dam stands at a height of 27 feet and has a hydraulic height of 21.9 feet, creating a reservoir with a maximum storage capacity of 79 acre-feet. Despite having a low hazard potential, the dam has a moderate risk assessment rating of 3, indicating the need for ongoing monitoring and maintenance to ensure its safety and integrity.

Managed by the Natural Resources Conservation Service, Smythe Lake Dam overlooks the scenic McClain Branch river/stream and covers a surface area of 4.2 acres. While the dam itself has not undergone any modifications in recent years, it is subject to regular inspections every five years to assess its condition. With uncontrolled spillways and outlet gates, the dam's emergency action plan status and risk management measures remain unspecified, highlighting the importance of proactive measures to mitigate any potential risks associated with its operation.

Water resource and climate enthusiasts can appreciate Smythe Lake Dam for its role in providing recreational opportunities in the area while also serving as a vital infrastructure for water storage and management. Its location in a picturesque setting, combined with its historical significance and engineering design, make it a fascinating site for those interested in the intersection of human-made structures with natural landscapes. As efforts continue to ensure the safety and sustainability of the dam, it remains a valuable asset for both the local community and the environment.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
