Shannon Pond Dam dam
Shannon Pond Dam
Shannon Pond Dam, located in Calhoun, South Carolina, is a privately owned structure built in 1970 primarily for fire protection and recreational purposes. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Shannon Pond Dam
Where does the data for Shannon Pond Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
