Summary
Primarily used for recreation, this earth dam on Gully Creek has a maximum storage capacity of 87 acre-feet and a normal storage of 50 acre-feet, covering a surface area of 8.8 acres. Despite its low hazard potential, the dam's condition assessment is rated as poor, indicating a need for maintenance and potential upgrades.
Owned privately, the J P Kneece Dam is regulated by the South Carolina Department of Health and Environmental Control, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulatory standards. The dam features a controlled spillway and buttress core type, serving as a popular spot for recreational activities in the area. However, its risk assessment is rated as very high, highlighting the importance of ongoing monitoring and risk management measures to prevent potential hazards.
With Joe Wilson (R) as the congressional representative for the district, the J P Kneece Dam plays a crucial role in providing recreational opportunities while also posing challenges in terms of its maintenance and risk management. As water resource and climate enthusiasts, it is essential to stay informed about the condition of such infrastructure and advocate for necessary actions to ensure the safety and sustainability of water resources in the region.

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.
