Aycock Pond Dam Dam
Aycock Pond Dam
Aycock Pond Dam, also known as Perry Aycock Dam, is a private dam located in York, South Carolina, along the TR-BRYSON CREEK. Built in 1967, this earth dam stands at 25 feet tall and stretches 700 feet in length, providing a storage capacity of 81 acre-feet for recreational purposes. Despite its low hazard potential, the dam's condition was assessed as poor during its last inspection in August 2017.
Managed by the South Carolina Department of Health and Environmental Control (DHEC), Aycock Pond Dam is regulated, permitted, inspected, and enforced by the state. While the dam is primarily used for recreation, its condition raises concerns about its safety and the potential risks associated with its poor maintenance. With its proximity to residential areas, further assessment and potential risk management measures may be necessary to ensure the safety of the surrounding community and the environment.
For water resource and climate enthusiasts, Aycock Pond Dam serves as a reminder of the importance of proper dam maintenance and inspection to prevent potential hazards and ensure the safety of communities and ecosystems. As discussions around dam safety and risk management continue, the condition of Aycock Pond Dam stands as a case study highlighting the need for proactive measures to address aging infrastructure and mitigate potential risks associated with deteriorating dams.

About Aycock Pond Dam
Where does the data for Aycock 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 below 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.

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.
