Twelve Mile Creek Wcd Dam 22 dam
Twelve Mile Creek Wcd Dam 22
Twelve Mile Creek WCD Dam 22, located in Pickens, South Carolina, is a crucial structure designed by the USDA NRCS in 1960 to reduce flood risks along the North Fork Twelve Mile Creek. Standing at a height of 41 feet and stretching 280 feet in length, this earth dam serves as a protective barrier against potential inundation, storing up to 1800 acre-feet of water. Its primary purpose is flood risk reduction, while also offering recreational opportunities for local residents and visitors.
Managed by local government authorities with oversight from the South Carolina Department of Health and Environmental Control (DHEC), Twelve Mile Creek WCD Dam 22 is subject to regular inspections to ensure its structural integrity and safety. Despite being classified as having a high hazard potential, the dam's condition assessment in 2020 rated it as fair, indicating a moderate risk level. While the dam currently operates with uncontrolled spillways and outlets, its management and maintenance protocols strive to mitigate any potential risks and uphold public safety standards.
As a significant component of the Savannah District's water resource management system, Twelve Mile Creek WCD Dam 22 exemplifies the collaborative efforts between local and federal agencies to safeguard communities from flood hazards and ensure sustainable water management practices. With its strategic location and design, this dam stands as a testament to the vital role of infrastructure in protecting our natural resources and adapting to the challenges posed by climate change.
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 Twelve Mile Creek Wcd Dam 22
Where does the data for Twelve Mile Creek Wcd Dam 22 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.
