Summary
The dam, situated on Occoneechee Creek, has a hydraulic height of 9 feet and a structural height of 12 feet, with a length of 285 feet. It provides a maximum storage capacity of 422 acre-feet, with a normal storage capacity of 352 acre-feet, making it essential for water supply in the area.
Despite being a low hazard potential dam, Johnson Millpond Dam #1 has not been state regulated or permitted, but it is regularly inspected by the state. The last inspection was conducted in 1976, with no condition assessment reported. The dam's emergency action plan status, risk assessment, and management measures are currently unknown. With its vital role in irrigation and water supply, this dam serves as a significant resource for the community while remaining under private ownership.
While Johnson Millpond Dam #1 may not have received recent attention or updates, its historical significance and importance for water management in the region cannot be understated. As climate change continues to impact water resources, it is crucial to ensure the safety and efficiency of dams like Johnson Millpond Dam #1 to meet the growing demands for water supply and irrigation in North Carolina.

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.
