Summary
This earth dam stands at a height of 14 feet and spans a length of 530 feet, with a storage capacity of 124 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2017 was deemed poor, highlighting the need for maintenance and potential upgrades to ensure its continued safety and functionality.
Managed by the South Carolina Department of Health and Environmental Control, Shannon Pond Dam is subject to state regulations, inspections, and enforcement measures to uphold safety standards and prevent potential risks. The dam's location along the TR-Cowpen Swamp river/stream adds to its ecological significance, providing water resources for local wildlife and recreational activities. With a surface area of 10 acres and a normal storage capacity of 44 acre-feet, the dam serves as a vital resource for the surrounding community and contributes to the overall environmental landscape.
As a key infrastructure for water management and conservation in the region, Shannon Pond Dam plays a crucial role in maintaining water levels, supporting biodiversity, and providing recreational opportunities. With its historical significance dating back to the 1970s, the dam's continued maintenance and upkeep are essential to ensure its longevity and functionality for future generations. As water resource and climate enthusiasts, it is important to monitor and support efforts to enhance the sustainability and resilience of structures like Shannon Pond Dam in the face of evolving environmental challenges.

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.
