Summary
Built in 1954, this private-owned earth dam stands at a structural height of 20 feet with a hydraulic height of 13 feet. The dam has a storage capacity of 50 acre-feet, with normal storage at 42 acre-feet and a surface area of 8 acres. Despite being classified as having a significant hazard potential, the dam's overall condition was assessed as fair during its last inspection in April 2013.
Situated on Turkey Creek in Nash County, this dam is not regulated by the state and does not have any associated federal agencies involved in its ownership, funding, design, construction, or operation. The dam has not undergone any modifications since its completion. Although there are no outlet gates or locks associated with the structure, the dam has a spillway type and width that were not specified in the available data. It is worth noting that the inspection frequency for Jeffries Lake Dam is listed as 0, indicating that regular inspections may not be mandated or have lapsed, potentially creating a need for updated safety measures and emergency action plans.
With its historical significance dating back over half a century, Jeffries Lake Dam is a vital piece of infrastructure for the local community's agricultural needs and leisure activities. Despite its fair condition assessment and significant hazard potential, the dam's role in providing water resources for irrigation underscores the importance of ongoing monitoring and maintenance to ensure the safety and reliability of this essential water management structure.

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.
