Summary
The dam, made of earth and buttress core types, stands at a height of 25 feet and spans 950 feet in length. With a storage capacity of 178 acre-feet and a surface area of 11 acres, the dam sits on TR-ROCKY CREEK and is regulated by the South Carolina Department of Health and Environmental Control.
Despite its low hazard potential, Cedar Lake Dam has not been assessed for its condition as of September 2018. The dam's risk assessment is moderate, indicating a level 3 risk. It is inspected every 5 years, with the last inspection conducted in September 2018. With a spillway type of uncontrolled and no outlet gates or locks, the dam poses a moderate risk, emphasizing the importance of regular inspections and maintenance to ensure its structural integrity and safety.
As a key recreational structure in the area, Cedar Lake Dam plays a vital role in providing leisure activities for the community. Despite its low hazard potential, ongoing risk assessments and inspections are crucial to maintaining its safety and functionality for all water resource and climate enthusiasts to enjoy for years to come.

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.
