Twelve Mile Creek Wcd 54a Dam
Twelve Mile Creek Wcd 54a
Twelve Mile Creek WCD 54a, located in Pickens, South Carolina, is a vital flood risk reduction structure managed by local government and private entities. Designed by USDA NRCS and regulated by SC DHEC, this earth dam stands at 36 feet high with a length of 350 feet, providing a storage capacity of 3,282 acre-feet. Completed in 1965, this dam plays a crucial role in reducing flood risk along Wolf Creek while also offering recreational opportunities for the community.
Despite being labeled as having a high hazard potential, the dam's condition is assessed as fair, with the last inspection conducted in April 2020. With a moderate risk assessment rating of 3, the structure meets regulatory guidelines and is subject to regular inspections to ensure its safe operation. While there are no associated structures or locks, the uncontrolled spillway and outlet gates serve their purpose effectively in managing water levels during high flow events.
As climate change continues to impact water resources, structures like Twelve Mile Creek WCD 54a play a crucial role in mitigating flood risks and protecting surrounding communities. With a focus on flood risk reduction and recreation, this dam serves as a testament to the collaborative efforts between local government, private entities, and regulatory agencies in safeguarding water resources in South Carolina.

About Twelve Mile Creek Wcd 54a
Where does the data for Twelve Mile Creek Wcd 54a 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 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.
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.
