Collum Pond Dam dam
Collum Pond Dam
Collum Pond Dam, located in Lexington, South Carolina, is a privately owned earth dam built in 1900 for recreational purposes. 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.

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.
- 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.
- 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.
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, environmental 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.

About Collum Pond Dam
Where does the data for Collum Pond Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
