Twelve Mile Cr Wcd Dam 12 Dam
Twelve Mile Cr Wcd Dam 12
Twelve Mile Cr WCD Dam 12, located in Pickens, South Carolina, was completed in 1954 with the primary purpose of flood risk reduction along the Rices Creek. This privately owned earth dam stands at a height of 32 feet and has a length of 235 feet, providing a storage capacity of 174 acre-feet. The dam is designed by USDA NRCS and regulated by SC DHEC, ensuring state inspection, enforcement, and permitting to maintain its structural integrity and safety.
With a hazard potential rated as high and a fair condition assessment as of April 2020, Twelve Mile Cr WCD Dam 12 poses a moderate risk level. The dam's uncontrolled spillway and outlet gates, along with its buttress core type, contribute to its flood risk reduction functionality. Despite the moderate risk assessment, the dam's emergency action plan and risk management measures are not specified, indicating a potential area for improvement to enhance preparedness and response in case of emergencies.
As an essential structure in the Savannah District under the ownership of a private entity, Twelve Mile Cr WCD Dam 12 serves as a critical component for water resource management and climate resilience in the region. With ongoing inspections and state regulation, this dam plays a crucial role in mitigating flood risks and protecting the surrounding communities and natural habitats along Rices Creek.

About Twelve Mile Cr Wcd Dam 12
Where does the data for Twelve Mile Cr Wcd Dam 12 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.
