Moss Grove Plantation Dam dam
Moss Grove Plantation Dam
Moss Grove Plantation Dam, located in Berkeley, South Carolina, is a privately owned earth dam built in 1988 primarily for recreational purposes. The dam stands at a height of 14 feet with a length of 325 feet, creating a reservoir with a storage capacity of 264 acre-feet. Despite its modest size, the dam is considered to have a high hazard potential and is currently in poor condition, as per the last inspection in October 2019.
The dam, situated on the TR-WEST BRANCH COOPER RIVER, is regulated by the South Carolina Department of Health and Environmental Control (SC DHEC) and undergoes regular inspections, with the next one scheduled in 2021. The surrounding area offers approximately 30 acres of surface water for recreational activities, providing a picturesque setting for water resource and climate enthusiasts to explore and enjoy. The dam's emergency action plan (EAP) status and risk assessment measures are currently not available, reflecting the need for continued monitoring and management to ensure the safety and integrity of the structure.
With its unique combination of historical significance as part of the Moss Grove Plantation and its recreational utility, Moss Grove Plantation Dam presents an intriguing case study for water resource and climate enthusiasts. By understanding its design, condition, and regulatory oversight, stakeholders can appreciate the delicate balance between human development and environmental conservation in managing water resources for both practical and leisure purposes. As discussions surrounding dam safety and resilience gain prominence in the context of climate change, Moss Grove Plantation Dam serves as a valuable example of the ongoing challenges and opportunities in this evolving field.

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 Moss Grove Plantation Dam
Where does the data for Moss Grove Plantation 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.
