Summary
With a height of 16 feet and a length of 650 feet, the dam has a storage capacity of 77 acre-feet, with a normal storage level of 65 acre-feet. The dam is situated on the TR-YARROW BRANCH river or stream and is regulated by the South Carolina Department of Health and Environmental Control (DHEC).
Despite its low hazard potential, the dam is currently in poor condition as of the last inspection in August 2017. The risk assessment for the dam is rated as moderate (3), indicating the need for potential risk management measures. While the dam does not have any associated structures or federal agency involvement, it is subject to state regulations, inspections, and enforcement to ensure public safety.
For water resource and climate enthusiasts, Myron Bolen Dam presents an opportunity to explore the intersection of recreational use and dam safety. As efforts continue to maintain and improve the condition of the dam, stakeholders can engage in discussions around risk assessment, emergency preparedness, and the sustainable management of water resources in the region. The unique characteristics of this privately owned dam make it a valuable case study for understanding the complexities of managing water infrastructure in a changing climate.

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.
