Summary
Standing at a height of 27 feet and stretching 487 feet in length, the dam has a storage capacity of 205 acre-feet and covers a surface area of 3.5 acres. The dam regulates the flow of TR-Turkey Creek and is under the regulatory jurisdiction of the South Carolina Department of Health and Environmental Control.
Despite its recreational focus, Frances and Bill Irwin Dam poses a high hazard potential due to its poor condition as of the last inspection in April 2017. The dam is subject to regular inspections every two years to ensure its structural integrity and safety. In case of emergencies, the dam does not have an Emergency Action Plan (EAP) prepared, highlighting a potential area for improvement in risk management and response measures.
With a risk assessment and management measures yet to be defined, Frances and Bill Irwin Dam serves as a critical water resource in the region, emphasizing the importance of proper maintenance and emergency preparedness to safeguard both the dam's structural integrity and the surrounding community from potential hazards. For water resource and climate enthusiasts, understanding the complexities of managing infrastructure like Frances and Bill Irwin Dam is vital in ensuring sustainable water management practices for future generations.

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.
