Summary
With a hydraulic height of 20 feet and a structural height of 24 feet, this dam has a significant hazard potential and a poor condition assessment as of the last inspection in May 2013. The dam has a storage capacity of 48 acre-feet and covers a surface area of 5 acres, with a drainage area specified.
Managed by the NCDEQ Dam Safety Program, Johnson Pond Dam is regulated by the state of North Carolina, with permitting, inspection, and enforcement processes in place. Despite its poor condition assessment, the dam has not been modified in recent years, and no emergency action plan (EAP) appears to have been prepared. The dam's location along Landrum Creek-Tr adds to its importance in providing vital water resources for the surrounding area and highlights the need for ongoing monitoring and maintenance to ensure its safety and functionality for both water supply and climate conservation efforts in the region.
Water resource and climate enthusiasts interested in Johnson Pond Dam will find its current status concerning, given its significant hazard potential and poor condition assessment. With its primary purpose of fire protection and stock pond, the dam plays a crucial role in water management in Chatham County, North Carolina. As a privately owned structure, the responsibility for its upkeep falls on the owner, with state regulatory agencies overseeing its operation and enforcement of safety measures. Continued monitoring and potential rehabilitation efforts will be essential to sustain this important water resource for the community and protect against potential risks associated with its condition.

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.
