Cooper Dev - East Dike dam
Cooper Dev - East Dike
Cooper Dev - East Dike, also known as Pinopolis East Dike, is a critical structure located in Berkeley, South Carolina, along the Cooper River. Built in 1942 by the Harza Engineering Company, this earth dam stands at a height of 25 feet and serves multiple purposes, including flood risk reduction, hydroelectric power generation, navigation, recreation, and water supply. With a normal storage capacity of 1,110,000 acre-feet and a surface area of 60,000 acres, this dam plays a vital role in managing the water resources in the region.
Managed by the Federal Energy Regulatory Commission, Cooper Dev - East Dike has a high hazard potential and poses significant risks if not properly maintained. While the condition assessment is currently not available, the emergency action plan was last revised in January 2021 to ensure preparedness in case of emergencies. The dam has three associated structures and is inspected annually to monitor its safety and integrity. Despite not being under state jurisdiction, this dam remains crucial for flood protection and water management in the area.
Cooper Dev - East Dike serves as a key infrastructure for mitigating flood risks and supporting various water-related activities in South Carolina. With its historical significance and ongoing efforts to ensure safety and resilience, this dam stands as a testament to the importance of effective water resource management and climate adaptation strategies. Enthusiasts and stakeholders alike can appreciate the intricate design and critical role that Cooper Dev - East Dike plays in sustaining the local ecosystem and community well-being.

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 - East Dike
Where does the data for Cooper Dev - East Dike 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.
