Cooper Dev - Pinopolis Dam dam
Cooper Dev - Pinopolis Dam
Cooper Dev - Pinopolis Dam, located in Moncks Corner, South Carolina, is a state-owned structure designed by the Harza Engineering Company. Completed in 1942, this earth dam serves multiple purposes including flood risk reduction, hydroelectric power generation, navigation, recreation, and water supply. Standing at a height of 138 feet, with a hydraulic height of 88 feet, the dam impounds the Cooper River, creating a reservoir with a storage capacity of 1,110,000 acre-feet and a surface area of 60,000 acres.
With a high hazard potential, Cooper Dev - Pinopolis Dam is under the jurisdiction of the Federal Energy Regulatory Commission, which oversees its inspections and regulatory requirements. Despite its age, the dam's condition assessment is not available, indicating a need for further evaluation. The Emergency Action Plan (EAP) for the dam was last revised in January 2021, ensuring that emergency contacts and guidelines are up to date in case of any unforeseen events. The risk assessment for the dam is rated as high, highlighting the importance of ongoing risk management measures to ensure the safety and integrity of the structure.
In addition to its functional roles, Cooper Dev - Pinopolis Dam is a significant landmark in Berkeley County, contributing to the region's water resource management and climate resilience efforts. As an essential component of the local infrastructure, the dam plays a crucial role in mitigating flood risks, providing renewable energy, and facilitating recreational activities for the community. As water resource and climate enthusiasts, staying informed about the maintenance and monitoring of dams like Cooper Dev - Pinopolis Dam is vital for ensuring the sustainability and safety of our water systems in the face of changing environmental conditions.

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 Cooper Dev - Pinopolis Dam
Where does the data for Cooper Dev - Pinopolis 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 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.
