Summary

The dam, standing at a hydraulic height of 12.9 feet and a structural height of 17.9 feet, helps create a surface area of 4.5 acres and a storage capacity of 32 acre-feet. While the dam has a fair condition assessment, it poses a high hazard potential, highlighting the importance of regular inspections and maintenance to ensure its safety and reliability.

Managed by the North Carolina Department of Environmental Quality's Dam Safety Program, Reynolds Lake Dam #1 is subject to state regulation, permitting, inspection, and enforcement. With Johnson Creek-Tr running nearby, the dam plays a crucial role in water resource management and recreational activities in the area. Despite its high hazard potential, the dam's condition assessment and emergency preparedness measures are in place to protect downstream communities in case of any unforeseen events.

The dam, under the oversight of the NCDEQ, serves as a vital infrastructure for water storage and recreation in Forsyth County. With a history dating back to its completion date and ongoing maintenance, Reynolds Lake Dam #1 stands as a significant structure for both water resource management and climate enthusiasts. Its presence contributes to the overall environmental and recreational landscape of the region, showcasing the intersection of human-made structures and natural resources in a delicate balance.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
