Summary
The dam, built on Marsh Branch, stands at a structural height of 16 feet and has a storage capacity of 140 acre-feet. The dam is classified as an earth dam with stone core and soil foundation, featuring an uncontrolled spillway and outlet gates.
Although the dam's hazard potential is rated as low, its risk assessment is moderate, indicating a level 3 risk. The last inspection of Mccullen Lake Dam was conducted in October 2015, with a condition assessment of "Not Rated." While the dam is not state-regulated, it undergoes regular inspections to ensure its safety and integrity. The dam has not been modified in recent years, and its emergency action plan status and risk management measures are currently not specified.
For water resource and climate enthusiasts interested in Mccullen Lake Dam, this structure provides a recreational feature in Duplin County. With its unique design and low hazard potential, the dam serves as a vital part of the local landscape. Monitoring of its condition and risk assessment are ongoing, highlighting the importance of maintaining infrastructure for safe water management in the region.

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.
