Cooper Dev - North Dike dam
Cooper Dev - North Dike
Cooper Dev - North Dike, also known as Pinopolis North Dike, is a key flood risk reduction structure in South Carolina, owned by the state and managed by the Federal Energy Regulatory Commission (FERC). Built in 1942 by Harza Engineering Company, this earth dam stands at a height of 15 feet and serves multiple purposes including flood risk reduction, hydroelectric power generation, navigation, recreation, and water supply. With a storage capacity of 1,110,000 acre-feet and a surface area of 60,000 acres, Cooper Dev - North Dike plays a crucial role in managing water resources in the region.
Located in Berkeley County, South Carolina, near the city of Russelville, Cooper Dev - North Dike spans over 33,264 feet along the Cooper River. Despite its high hazard potential, the condition assessment for this structure is currently not available, emphasizing the importance of regular inspections and risk management measures. It is interesting to note that the dam is not regulated by the state and does not fall under state jurisdiction, but is inspected by FERC to ensure its operational safety and integrity. The surrounding area has a history of flooding, making Cooper Dev - North Dike a vital asset for mitigating flood risks and ensuring water resource sustainability in the region.
As a significant component of the water infrastructure in the Charleston District, Cooper Dev - North Dike has been designed to withstand high hydraulic pressures with a spillway width of None. With its rich history dating back to 1942 and a storage capacity of 1,110,000 acre-feet, this earth dam continues to be a critical asset for flood risk reduction and water management in the area. Its strategic location along the Cooper River highlights the importance of maintaining and monitoring this structure to ensure the safety and security of the surrounding communities and water resources.

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