Summary
Standing at a height of 22 feet and spanning 570 feet in length, this dam holds a storage capacity of 225 acre-feet, with a normal storage level of 114 acre-feet. The dam is situated on Little Black Creek and is under the regulatory jurisdiction of the South Carolina Department of Health and Environmental Control (DHEC).
Despite its low hazard potential, the dam's condition assessment in 2017 rated it as poor, signaling areas of concern that may require maintenance or repair. The risk assessment for Collum Pond Dam classified it as having a very high risk level, indicating the need for proactive risk management measures to ensure the safety and integrity of the structure. With a controlled spillway and a limited inspection frequency of every 5 years, it is crucial that ongoing monitoring and maintenance efforts are prioritized to mitigate any potential safety risks associated with the dam.
Enthusiasts of water resources and climate will find Collum Pond Dam to be an intriguing structure due to its historical significance, recreational purpose, and the need for continued monitoring and maintenance to ensure its safety and functionality. As one of the many dams in South Carolina regulated by the state, Collum Pond Dam serves as a reminder of the importance of responsible dam management practices in safeguarding communities and the environment from potential risks associated with aging infrastructure.

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.
