Mixon Pond Dam dam
Mixon Pond Dam
Mixon Pond Dam, located in Barnwell, South Carolina, is a privately owned structure built in 1972 primarily for recreational purposes. The earth dam stands at a height of 12 feet and spans a length of 550 feet, creating a storage capacity of 252 acre-feet. Despite its modest size, the dam poses a high hazard potential and has been assessed to be in poor condition as of January 2019.
The dam is regulated by the South Carolina Department of Health and Environmental Control (DHEC), with state permitting, inspection, and enforcement all in place to ensure compliance with safety standards. The dam's location on Tinker Creek adds to its significance for water resource and climate enthusiasts, as it contributes to the overall hydrology of the area. However, with its current condition and hazard potential, there is a need for ongoing monitoring and potential risk management measures to address any safety concerns.
With its proximity to the city of Barnwell and its association with recreational activities, Mixon Pond Dam serves as a focal point for both local residents and visitors. The dam's history, design, and operational details provide valuable insights for those interested in water resource management and climate impacts on infrastructure. As efforts continue to maintain the dam's safety and functionality, it remains a key component of the region's water resources landscape.

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 Mixon Pond Dam
Where does the data for Mixon 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 High 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.
