Massengill Millpond Dam Reservoir Report
Nearby: Regal Pond Dam Mcgee Lake Dam
Last Updated: February 24, 2026
Massengill Millpond Dam, located in Macks, Johnston County, North Carolina, was completed in 1900 for the primary purpose of recreation.
Summary
This private earth dam on Black Creek stands at a hydraulic height of 8 feet and a structural height of 10 feet, with a length of 627 feet. It has a storage capacity of 85 acre-feet and a drainage area of 1235 acres, making it a significant water resource in the area.
The dam's inspection in May 2013 found its condition to be satisfactory, with a significant hazard potential. Despite not being state-regulated, the dam is regularly inspected and holds a normal storage capacity of 72 acre-feet. With a high risk of inundation, the dam poses a potential threat, highlighting the importance of ongoing risk assessment and management measures to ensure the safety of the surrounding community and the preservation of this vital water resource.
As a favorite spot for recreational activities, Massengill Millpond Dam serves as a reminder of the delicate balance between human enjoyment and environmental safety. Its historical significance and impact on the local ecosystem make it a focal point for water resource and climate enthusiasts, underscoring the importance of responsible stewardship and proactive maintenance to safeguard its integrity for future generations.

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.
