Summary
Completed in 1996, this Earth-type dam serves the primary purpose of creating a Fish and Wildlife Pond along the Log Creek. With a dam height of 17 feet and a storage capacity of 89 acre-feet, the dam covers a surface area of 8 acres and supports a normal storage level of 45.1 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 reported poor conditions, highlighting the need for maintenance and inspection.
Managed by the South Carolina Department of Health and Environmental Control (DHEC), Jon Prince Dam is subject to state regulation, inspection, and enforcement. However, with its uncontrolled spillway type and outdated structural assessment, the dam poses a moderate risk to its surroundings. The dam's emergency action plan and risk management measures remain unclear, raising concerns about its ability to withstand potential hazards. As water resource and climate enthusiasts, it is crucial to monitor the condition of dams like Jon Prince to ensure environmental sustainability and public safety in the face of changing climate patterns.

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.
