Summary

Completed in 1964, this earth-type dam has a hydraulic height of 23.7 feet and a structural height of 28.5 feet, with a total length of 300 feet. The dam has a storage capacity of 384 acre-feet and covers a surface area of 14.5 acres, serving the surrounding area for recreation and water supply.

With a high hazard potential and a fair condition assessment as of January 2021, Cedar Hollow Dam is regularly inspected by the North Carolina Dam Safety Program to ensure its safety and compliance with regulations. The dam is situated on Mears Fork Creek-Tr and has a drainage area of 333 square miles. Despite its primary purpose of recreation, the dam plays a crucial role in managing water resources in the region and is a significant feature of the landscape in Altamahaw.

As a key infrastructure in the area, Cedar Hollow Dam provides not only recreational opportunities but also serves as a vital resource for water management in Guilford County. With its strategic location and storage capacity, the dam contributes to the overall water supply and ecosystem health in the region. As climate and water resource enthusiasts, understanding the significance and condition of structures like Cedar Hollow Dam is essential for sustainable water management practices and environmental conservation efforts.

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.
