Larry L Yonce Pond Dam dam
Larry L Yonce Pond Dam
Larry L Yonce Pond Dam, located in Edgefield, South Carolina, stands as a significant structure along the TR-South Fork Edisto River. Built in 1910, this private-owned earth dam serves as a vital water resource with a storage capacity of 130 acre-feet. Despite its age and historical significance, the dam's condition assessment has been rated as poor, indicating a need for maintenance and potential risk mitigation measures.
With a height of 14 feet and a length of 390 feet, Larry L Yonce Pond Dam plays a crucial role in regulating water flow and storage in the region. However, its poor condition and significant hazard potential highlight the importance of regular inspections and maintenance to ensure the safety and functionality of the dam. The dam's structural integrity and emergency action plan readiness are areas that require immediate attention to safeguard against any potential risks or incidents.
As water resource and climate enthusiasts, it is essential to monitor and advocate for the proper maintenance and management of dams like Larry L Yonce Pond Dam to protect not only the local ecosystem but also the surrounding communities that rely on its water storage and regulation capabilities. By staying informed and engaged in the upkeep of vital infrastructure like dams, we can contribute to the sustainability and resilience of our water resources in the face of changing climates and environmental challenges.
Dam data reference
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 Larry L Yonce Pond Dam
Where does the data for Larry L Yonce 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 Significant 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.
